How To Cut Metal Panels

Posted on October 21, 2020May 31, 2023 by Tyler Roose

Even with an accurate materials list, cutting metal roof and wall panels on-site is often a necessary part of the installation process. To avoid damaging your metal panels, it’s important to use the correct tools and overall best practices. Learn more about how to cut metal panels.

Safety Precautions

Before cutting your metal panels, take appropriate safety precautions to avoid getting hurt. Use gloves to protect your hands from being cut by the sharp metal panel edges. If metal filings fall on the surface of your metal panel, try to blow them off instead of touching them with your hands. Put on safety goggles to protect your eyes from airborne metal filings.

Tools

To avoid damaging the panels or their coating, it’s important to use proper tools. Snips are generally recommended for trim work while shears and nibblers are used for the panels themselves. Some of the best tools to use include:

● Aviation Snips: Good choice for small cuts, including cuts near pipe penetrations.
● Electric Shears: Ideal for lengthier cuts along steel.
● Mechanical Shears: Add-on tool that fits into an impact or screw gun. Ideal for use on standing seam panels at hips and valleys.
● Nibblers: Also known as turbo shears, they’re ideal for cutting openings for windows and doors.

Skill saws can also be used if this is the only resource available. Be sure to use a blade that is specifically designed for metal panels. Turn the panel upside down so that the painted side is facing the ground to make sure filings don’t stick to the paint coating.

Avoid Using:
● Torches
● Cut-Off Saws
● Reciprocating Saws
● Hacksaws
● Grinders

These tools heat up the metal panel and can melt or damage the edge that was cut. They can also cause metal filings to go airborne, creating a safety hazard. If those metal filings stick to the panel’s painted coating, they can cause surface rust.

Cutting Metal Panels

Marking the Panels

Before cutting your panels, be sure to measure and mark the cuts you’re planning to make. To mark your panels, lay them down flat with the painted side down. Make sure the panel is stable by clipping the panel in with c-clamps.

Do not mark on the finished side of the panel to avoid marring the visible surface. Avoid using a pencil with graphite lead as this is a dissimilar metal and could cause your metal panel to corrode. Instead, use a chalk line or magic marker. Use a straightedge or combination square to draw a straight line.

Cutting Technique

Before making a cut, be sure to line up the snip blade with the marking. Keep the blade perpendicular to the metal sheet you’re cutting. Work slowly and make steady and consistent cuts for smoother lines. Keep your cuts short to avoid jagged edges. For quicker, straighter cuts, use nibblers or mechanical shears.

Improve Efficiency by Planning Ahead

Cutting metal panels and trim in the field is easily one of the most time-consuming parts of the installation process. To avoid extra cutting in the field, it’s important to create an accurate materials list upfront. To do this, plan out how your panels will cover the roof or wall areas. Make sure the coverage width and count of the panels ordered is sufficient to cover the area you are installing. Consider which side of the building you will start with and how the ends of the wall or roof will be finished. It is possible that you may be able to avoid splitting a panel lengthwise if you do proper calculations in advance. Additionally, some panels are only able to be installed in one direction. Next, review the standard trim details such as valleys, hips, and around doors and windows. Be sure you have appropriate panels to cover these areas as well, and order to the closest pre-cut length available.

Selecting & Applying Metal Roofing Touch-Up Paint

Posted on September 15, 2020May 31, 2023 by Martin Thompson

Our metal roofing panels are designed for durability, featuring a baked-on paint finish that covers the Galvalume®-coated steel surface. This helps to preserve the look and functionality of your metal roofing panels for decades with minimal maintenance. Over the life of your metal roofing panels, however, it is possible that the baked-on paint finish can be damaged. For minor scratches, you are able to use touch-up paint to preserve the aesthetic appeal of your metal roof. Learn more about selecting and applying metal roofing touch-up paint.

What Causes Scratches & Dents?

Metal roofing panels are most commonly damaged during the installation process. To avoid scratching or denting your metal roofing panels, it’s important to store them properly and use caution when unpacking and installing them. Store them at a slight angle in a dry location that is out of the way of foot traffic and ongoing construction. Avoid dragging panels across each other when unbundling to prevent damage to the paint coating.

After metal roofing panels have been installed and before the installer leaves, walk around the building to look for scratches and dents within normal view. Address these issues with your installer.

After the installation process is complete, there are additional considerations to protect your metal roof from damage. Keep trees trimmed to prevent overgrown branches from scratching your metal roof panels. Additionally, use caution when walking on the roof or using tools as these activities could damage the paint coating. Check your roof for damage at least once a year as part of your annual maintenance routine to keep it in good condition.

Assess the Damage

If you find a scratch during routine maintenance or a post-installation check, start by assessing the damage. How noticeable is the scratch? Is the panel scratched down to the bare metal? These are important questions to ask when deciding whether to use touch-up paint or replace the panel altogether.

Use touch-up paint for light scratches that only affect the paint coating or for hairline scratches down to the bare metal. touch-up paint fades more quickly than the baked-on paint coating, especially with bright or dark colors. As a result, covering a sizable area with touch-up paint could create more of a problem as the touch-up paint begins to fade over the next couple of years which would be more noticeable than leaving it alone. If your panel has large scratches or gouges that go down to the bare metal, consider replacing it instead.

Choosing Touch-Up Paint

When choosing touch-up paint for your metal roof, it’s important to make sure that it’s compatible with the existing paint coating. The best way to do this is by purchasing touch-up paint from your metal roof panel manufacturer. Most manufacturers offer small containers of high-quality paint that are designed to match the color of your existing roof panels.

How to Apply Touch-Up Paint to Metal Roofing

When applying touch-up paint, make sure to read the specific instructions provided by your manufacturer.

In general, you will complete the following steps to apply touch-up paint:

Make sure the surface temperature of your roof is 50 F.
Clean the area by wiping it down with isopropyl alcohol. Make sure the surface is dry and free from contaminants before moving on.
If the bare metal of the panel is showing, apply acrylic primer.
Apply touch-up paint to the area using the dobber (or a small artist brush). Multiple coats may be likely to achieve the desired film thickness.
Touch-up paint should be tack free within 30-45 minutes.
It should dry completely within 24-48 hours.

Benefits of Metal Panels for Agricultural Buildings

Posted on May 26, 2020May 31, 2023 by Joe Sample

Metal panels are ideal for agricultural buildings, including those that house livestock, such as cattle, hogs and poultry. They’re durable and offer flexibility in design so you can create an agricultural building that is functional and aesthetically pleasing. Read below to learn more about the benefits of choosing metal panels and special considerations for animal confinement.

Why do so many agricultural buildings use metal panels?

Durability: Metal panels are designed for durability. They can withstand high winds and heavy snowfall. They’re also hail resistant, featuring a class 4 rating. Unlike wood, metal panels are resistant to damage from termites and other insects. Metal is also noncombustible.
Longevity: Metal panels last three to four times longer—up to 60 years. Unlike corrugated fiberglass panels, metal doesn’t get brittle after years in the sun.
Cost Savings: Metal is a much more cost-effective material than wood because it doesn’t need to be replaced as often. The durable design of metal panels also saves money on maintenance.
Sustainability: Our metal panels are made from recycled materials. They’re also 100% recyclable at the end of your building’s life. Choose from a variety of cool roofing colors that are designed to reflect the sun’s heat instead of absorbing it into your agricultural building.
Ease of Installation: Metal panels can be cut to the nearest 1/4 of an inch for easy installation. Most panels offer three feet of coverage which is more time-efficient than pounding out shingles.
Design Flexibility: There are a variety of options to choose from when it comes to metal panels. We offer a broad selection of styles, profiles, colors and finishes.

The common panel profile used for this application is Imperial Rib® . It’s designed for durability with two minor ribs which give it strength. It’s also formed with a round top which pushes away moisture.

Metal Panels for Livestock Shelters

Animal confinement imposes specific challenges on panels that aren’t required considerations for residential or commercial uses.

When considering metal panels for a barn or other animal enclosure, here is what you should keep in mind.

What makes animal housing such a challenge?

Animal waste has high ammonia content that can start to corrode metal in as little as five years. With roofs, this corrosion is fueled by airborne fumes; on walls, the culprit is manure or dirt lying against the panels for extended periods. You can minimize both problems with good ventilation and regular maintenance, including keeping the panels clean and immediately repairing any damage.

Important Considerations

Panel Coatings: More people are opting for Galvalume panels for their livestock housing projects than ever before. And while Galvanized panels perform better than Galvalume in high-ammonia environments such as hog confinement, Galvanized panels are susceptible to white rust (chalking) if exposed to water prior to installation, which is not an issue with Galvalume panels.

For this reason, many are pairing Galvalume panels with a protective, self-adhesive moisture barrier like ABC’s Drip Stop product, which is applied to the panel’s interior before it is roll-formed. This membrane absorbs moisture when relative humidity (RH) is high, and then releases it back into the atmosphere when the RH falls, thereby preventing the damaging moisture from directly touching the panels. For hog or cattle barns, where dirt and manure tend to pile up against walls, another protective option is to install a polycarbonate panel on the inside of the metal wall panel to reduce contact, making the metal panels easier to keep clean.

No matter which panel you choose, be sure you understand how the coating is measured to that you optimize the durability and long-term corrosion resistance. The best options are the G90 Galvanized or AZ55 Galvalume panels, which have been compared in this article.

Panel Thickness: The 29-gauge panel is most commonly used for animal confinement, but as mentioned in this article on metal panel gauges, nominal 29-gauge panels come in a range of actual thicknesses. For best results, look for one that’s at least .015 inches thick.
Design: The design of animal confinement structures is important and can have major impacts on the viability of the building. Dropped ceilings with sophisticated ventilation systems are said to increase efficiency and satisfy environmental run-off inspections, therefore maximizing return on investment. These structures can also be designed to help eliminate ammonia fumes and corrosion- common occurrences in buildings with poor air flow.
Warranty: As with any purchase, it’s important to check the warranty exclusions when selecting any kind of panel for your projects. For instance, the warranty on a Galvalume panel may not apply when it’s subjected to animal waste or other corrosives. Again, good ventilation and regular maintenance will minimize the chance of problems.

Mixing Metal Panels into Building Designs

Posted on October 24, 2019May 31, 2023 by Tyler Roose

One major benefit of building with metal is its unparalleled versatility. In addition to its durability and longevity, mixing metal panels into building designs can update the appearance of any structure. Available in a variety of textures, shapes, finishes and colors, the design possibilities and flexibility afforded to designers, architects, contractors and homeowners are endless. These panels are a durable option which offers a lengthier life span than several other materials.

Mixing Metal Panels with Traditional Materials

To add contrast and texture metal panels seamlessly pair with traditional building materials like shingles, wood shake and siding, stone and others. Metal panels can be used to modernize the exterior of any structure. From residential buildings to restaurants, commercial buildings, car washes and shopping centers, there are several ways to integrate metal within the design of a building:

Mix metal roofing panels with brick, stone or wood for added durability:

Splash and Dash Car opted for vibrant metal roofing panels on their commercial car wash.

ABC metal panels were used in conjunction with stone on this residential property.

Add an eye-catching exterior accent wall to mix metal wall panels into your design.
Thinking about creating an attached porch or carport? Metal panels can easily integrate with shingles or other traditional roofing materials.

ABC metal panels were used for this residential porch addition.

When mixing metal panels with other building materials it’s important to hire an experienced contractor and refer to the specific product manuals for installation.

This will help ensure the transition from the original material to metal panels is seamless. In addition to correctly trimming the metal panels to prevent ice and snow dams, they can also help ensure trim pieces are flashed beneath the existing shingles, so you can easily replace your existing roof in the future, if necessary.

Mixing Metal Panels

Another option for creating contrast within the design of your metal building is to utilize different metal panel profiles. There’s no limit to the number of panels you can combine to bring your vision to life. Try one panel profile on your roof and add another wall panel for the siding. You can also mix and match panel colors to add character to the exterior of your building.

With this approach, you can enjoy the lengthy lifespan of metal building materials without sacrificing the aesthetic appeal you desire. Mix metal panels on buildings for any application including residential buildings such as homes, agricultural facilities and hobby shops, as well as commercial buildings like workshops, restaurants and auto repair shops.

Cleaning Metal Panels Part 2: Quick Tips to Consider

Posted on September 26, 2019May 31, 2023 by Joe Sample

In a recent blog post, we reviewed how regularly cleaning metal panels helps maintain their integrity and aesthetics. Now that you know the importance of this activity, we’re sharing some tips for cleaning metal panels to consider.

LEVELS OF CLEANING METAL PANELS:

These tips for cleaning metal panels are based on general circumstances and get progressively more detailed for tougher jobs. They should not supersede and are not a replacement of the any metal panel manufacturer’s instructions or warranty requirements, including those provided by American Building Components.

Light Cleaning:

For simple cleaning, water and mild detergent is often sufficient. However, never use bleach, as it can change the finish color or interact disastrously with certain metals.

Moderate Cleaning:

For dirt or other deposits that can’t be removed with water alone and require a more complete cleaning, a solution of hot or cold water mixed with detergent is appropriate. An ideal solution is the mixture of 95 percent water with 5 percent of a mild, commonly-used, commercial (non-industrial, non-bleach) dish or laundry detergent added. Diluting the detergent with the water helps ensure the detergent isn’t too strong and doesn’t negatively affect the painted metal surface. Common cleaners for this type of cleaning can include:

Mild laundry detergent
Car wash soap
Mild dish soap
Cold or hot commercial/industrial detergents

Deep Cleaning:

For non-water-soluble residue such as tar, tree sap, grease, oil and adhesives, a solvent or alcohol-based cleaning solution may be required. In this case—since most organic solvents are flammable and/or toxic—handle these according to the cleaner and manufacturer instructions.

Generally, it’s advisable to keep them away from open flames, sparks and electrical motors. Use adequate ventilation, protective clothing and goggles, and—of course—read the manufacturer’s Material Safety Data Sheet (MSDS) for any solvent used for any other specific safety details.

Common cleaners for this type of non-water-soluble cleaning often include:

Alcohols:
- Denatured alcohol (ethanol)
- Isopropyl (rubbing alcohol)

Solvents:
- VM&P Naptha
- Mineral Spirits
- Kerosene
- Turpentine (wood/gum spirits)

WHAT TO AVOID WHEN CLEANING METAL PANELS:

It’s important to avoid using products and tools not recommended by the panel manufacturer that will scrape or grind down the surface coating and leave scratches or other finish damage when cleaning metal panels. This can eventually wear down the finish and leave panels vulnerable to corrosion. Likewise, any misuse or abuse of acceptable cleaning agents will likely automatically void any manufacturer’s warranty for the affected surfaces.

Regardless of the level of cleaning that needs to be done, there are some products and tools that are likely never ideal for use on coated metal panels. These include:

Wire brushes
Abrasives
Steel wool
Sandpaper
High-pressure power washers
Scouring powders
Paint removers
Paint thinners

In conclusion, while the considerations above can help give you and your customers an idea of options available when cleaning metal panels, the importance of understanding and following the specific product manufacturer’s metal panel cleaning instructions can’t be overstated. As a result of diligently following all official instructions and considering these tips, your customers can avoid panel corrosion, staining or other surface damage and retain the integrity and beauty of the metal panel finish.

Cleaning Metal Panels – Part 1: Why it Matters

Posted on August 29, 2019May 31, 2023 by Marc Carolan

Metal roof and wall panels often feature long-lasting and durable finishes available in many colors. These finishes protect the panels and enable them to hold up and look great for decades. However, to maintain their durability and protective properties, cleaning metal panels should be done regularly throughout their service life.

THE IMPORTANCE OF REGULARLY CLEANING METAL PANELS:

Ensure Panel Longevity:

Dirt and residue left on metal panels can damage their protective coating and decrease the longevity of roof and/or wall systems. Likewise, bacteria and mold and mildew build-up can accelerate corrosion to the point where the structural integrity of the panels is compromised.

Protect Panel Appearance:

Stains and algae/lime deposits left on panels for long periods of time can degrade the roof finish to the point where it must be re-coated. Note: re-coating should only be considered if the panels are still structurally sound and doing so wouldn’t void the manufacturer warranty.

Control Energy Costs:

Dirty roof panels can inhibit a roof’s ability to expel heat from a building. If the heat isn’t able to escape through the roof, it can require increases in energy costs to keep the building cool.

HOW OFTEN DO METAL PANELS NEED CLEANING?

An annual cleaning helps keep your metal panels free of tree and animal debris, moss, fungus and other finish-jeopardizing elements. Deep cleaning metal panels only typically needs to be done every 3-5 years, depending on the building conditions and location. This type of cleaning uses stronger detergents that cut through some of the toughest dirt and grime that annual cleans can miss. This includes substances such as tree sap, oxidation and other hard-to-remove substances that often collect on panel surfaces. You may also consider moderate cleaning following weather events and seasonal allergen build-up.

WHO SHOULD CLEAN METAL PANELS?

Above all, follow the panel manufacturer’s recommendations when it comes to selecting who will perform panel cleaning on your building. Before you attempt to clean your metal panels yourself, be sure the product manufacturer recommends it and doing so doesn’t void any warranties.

A professional building surface cleaning company can be helpful as working on top of buildings can pose real safety risks. Your metal panel manufacturer may be able to recommend cleaning professionals who are familiar with their products and warranty requirements, and are practiced in using the correct cleaning solutions and techniques necessary to preserve your metal panels.

THE IMPORTANCE OF FOLLOWING MANUFACTURER MAINTENANCE INSTRUCTIONS:

Metal panel manufacturers usually provide maintenance and cleaning instructions specific to their products, which should always be followed. Manufacturers know the composition of their products and, therefore, which chemical cleaning solutions and techniques are ideal and which will degrade the panels. Neglecting to clean them—or doing so improperly—can compromise the integrity of the finish. Not only can this threaten the visual appeal of the panels, it can also put you at risk of voiding the panel warranty.

Roofing and Snow: Everything You Need to Know – Part Two

Posted on November 13, 2018May 31, 2023 by Ken Buchinger

Additional considerations for working with metal panels in winter.

In part one of our series on metal roofing and snow, we covered five of the most important elements to consider when preparing structures for winter weather. In this post, we’ll review four more ways to prevent unexpected, costly damage of metal panels in winter.

Consider roof material and surface color

Metal roofs absorb heat quickly and radiate it effectively. Darker panel colors can enhance this solar absorption effect, which can save you money year-round. But because UV light can pass through 3-5 inches of snow, when combined with heat loss through the roof, it becomes more difficult for snow to stay solid. To minimize the chance of ice damming, you should ensure your roof system is properly sealed and insulated. If not, ice damming may occur and the melting and re-freezing of snow throughout the day can result in icy layers that promote snow sliding—no matter the roof material or color.

Review weathertightness factors

For low-sloped roofs (less than 3:12), it is especially important for panel seams to be watertight to prevent water (melted snow) from leaking into the structure. This can be problematic when snow gathers and stays on a roof. Architects, designers and specifiers, therefore, should consider using panels that have passed the ASTM 2140 water head test or FM 4471 Appendix G water test. Water-resistant underlayment should also be considered for all roof slopes.

A close-up of this dormer roof illustrates how the impact of sliding ice and snow can damage panel seams.

Consider your roof layout

Design elements like valleys and slope changes cause snow to collect and increases your snow load. Also, when dormers extend from a large roof area and one area is significantly bigger than the other, the structure is susceptible to experiencing unbalanced sliding snow. This imbalance can actually tear open standing seams and displace panels. Also consider that drifting snow may accumulate behind HVAC units, at perimeter walls, and behind solar and photovoltaic (PV) panels.

Ensure Proper Roof Maintenance

One of the best ways to prevent snow and ice issues is to regularly inspect and maintain your roof. In addition to cleaning and inspecting your roof for possible issues, properly removing standing snow and preventing ice dams is a vital part of avoiding damage to your metal panels in winter. This often requires that you get into your attic to inspect for air leaks—the leading cause of ice dams. Read more about how to properly maintain and remove snow from your roof in this blog post.

If an issue is discovered, consult your roofing material manufacturer for recommendations as well as advice on warranty claims. Additionally, you can reach out to a trusted roofing professional in your area. These professionals can thoroughly inspect your roof system to help you determine ways to rectify any potential issues. You’ll want to do this before damage and/or injury occurs and before you pay for sub-par or ineffective repairs.

If you missed part one of this series, click here for our top five considerations. These include managing snow load and sliding snow, preventing ice dams, using retention systems and more! For more information on how metal panels fare in winter weather conditions and for advice on how to winter-proof your roof, reach out to an ABC representative today.

Roofing and Snow: Everything You Need to Know – Part One

Posted on October 4, 2018May 31, 2023 by Ken Buchinger

What to consider when designing and building in snow-prone areas.

While properly-designed metal roofs historically perform well in winter, heavy snowfall can be detrimental to buildings of all kinds. Those who live and work in and around them are also at risk when snow and ice cause dangerous situations. Even though winter doesn’t formally begin until late December, colder weather is upon us. And while you might not be expecting snow or ice yet, keep these roofing and snow tips in mind when designing, constructing and maintaining structures in areas where there’s a chance for snow and/or ice over the course of the year.

Considerations for Snow-Bearing Roofs:

Anticipate Snow Load

Snow accumulates on every roof type, and as this happens, it increases the amount of weight your structure is bearing. This increased weight (snow load) can pose several threats to the structure and those in and around it. For example, when the weight of snow or ponded water from melted snow exceeds the structure’s limits, the roof or even the entire structure can collapse. Be sure you’re aware of the weight your structure can bear and remove snow to keep it within its limits. Consult the International Building Code (IBC) as well as state and local codes for guidance based on your location.

Prevent Ice Dams

Most ice dams are the result of air barrier flaws in buildings. If warm indoor air escapes through the roof floor, it warms the roof sheathing and melts the underside of the layer of snow on top. This water then moves down the slope of the roof toward the eaves, where it freezes into ice. As this process continues, the ice gets thicker and thicker, resulting in ice dams. The presence of these dams allow water to back up and form a reservoir that can cause major damage.

To prevent ice dams, you should:

Seal all air leaks at the attic floor
Ensure proper insulation
Provide adequate attic ventilation

Another tip is to use a peel and stick membrane on the roof deck extending from the eave to about 3’ up-slope from the exterior wall. For more specific details on the ice dam prevention tips above, read our recent blog post.

Prevent Sliding Snow

Gravity can cause accumulated snow to slide down the roof’s slope (shedding), potentially injuring people and damaging property below. Despite this, snow shedding must occur to keep the snow load from accumulating beyond the buildings structural limits. Balancing snow load and shedding is important and requires that you consider geographical and building material and roof design factors.

Ice and snow sliding down the main roof has damaged the roof panels and the valley trim on this connector roof.

Roof slopes of 45 degrees (12:12) or more, can accelerate sliding snow with sometimes immense and dangerous consequences. For example, if snow accumulates and then falls onto an exterior gas line, pipes could rupture. From there, the smallest of ignition sources could set the structure ablaze. In addition, the weight of sliding snow can propel any icicles formed on eaves can be propelled down by the force and weight of sliding snow onto people and property below.

On slopes less than 45 degrees (6:12 to 9:12), low amounts of friction (like on smooth roof surfaces) means it offers less resistance to sliding. Striations and embossing on roofing materials like metal panels add a small 3D profile and improve the resistance to sliding, especially when they run traverse to the slope.

This can get complicated, but in general, installing metal panels with snow retention devices on a steeply-sloped roof is recommended. This approach will naturally shed snow and ice, and protect your structure from excessive snow loads. If you have a low-sloped roof, be sure it’s design supports snow as shedding won’t occur naturally. Including enough snow retention devices from ridge to eave is also imperative for this design.

Use Retention Systems

A variety of retention options, such as snow fences, bars or guards, are designed to make snow and ice melt completely or fall from roofs in small amounts. This helps reduce risks associated with sudden rooftop avalanches while maintaining the clean lines of the roof. It is important that snow retention systems are carefully engineered and properly installed. Models like S-5!’s snow-retention device design resource allow you to input your roof dimensions and expected snow load to adequately engineer snow fence assemblies.

Protect Roof Attachments

This pipe penetration is protected from sliding ice and snow by a small section of S-5! ColorGuard to the panel seams immediately up-slope from the pipe.

The weight of sliding snow can be powerful enough to take off attachments like exhaust vents. To combat this, reduce the shear load by installing rigid vent pipes securely and as high up on the roof slope as possible. If this is not possible, protect the pipes with a snow retention system.

While metal roofing responds well to harsh winter weather, it is imperative to take the time to keep snow, ice and moisture from causing issues. No matter the roofing design or material used, keeping people and property safe from overhead dangers should be a priority when designing, installing and maintain your structure.

In part two of this roofing and snow series, we’ll review additional considerations. It contains tips on roof layout, color, weathertightness and maintenance, which also play important roles in winter weather protection.

Advancements in Metal Roof and Wall Panels

Posted on July 26, 2018May 31, 2023 by Marc Carolan

The evolution of metal roof and wall panels in the steel building industry.

Metal roof and wall panels are commonly used in today’s building industry and are highly valued for their versatility, durability and aesthetic features. This wasn’t always the case, though. Over the last several decades, the metal building industry has evolved and the use of metal panels and coordinated metal building components is now a major boon for builders as it helps them provide on-time, on-budget, attractive project to a wide-ranging customer base.

To meet changing demands and standards, the industry has continued to develop and progress since the Industrial Revolution. This era saw more than just an increase in the use of iron as a construction material. In the late 1880s, metal became a profitable option well-suited for steel-framed buildings, skyscrapers and train stations. During WWII and in the decades that followed, modern steel became the universal standard. Common uses included military shelters, oil storage, churches and private buildings—including landmarks like the Empire State Building.

1940s – 1950s:

During the 1940s and 1950s, industry sales centered around standardized buildings (pre-engineered)—mostly to the agricultural, industrial and government markets. Typically unpainted and unattractive, these metal roof and wall panels simply met their functional purpose. However, their ability to be ordered, delivered and installed quickly and easily made them very valuable.

1960s:

The innovation of pre-painted wall panels in 1959 transformed the metal building industry. Formerly focused on agricultural and industrial end-uses, the additional color options made metal panels more appealing to commercial markets. In the late 1960s, the innovative standing-seam metal roof panel delivered advantages previously unheard of. As seen with American Building Components’ LokSeam® panel, this design features fewer seams that are raised above the panel. With fasteners situated above the panel level, the risk of damage from moisture that can collect there is reduced. Standing seam metal roofs are also designed to allow for expansion and contraction that naturally occurs as a result of changing temperatures. This provided owners, designers and contractors with a high-quality roof that can be specified and used for large buildings. Their low upfront cost and superior performance and lifespan made metal buildings the preferred solution for low-rise, non-residential buildings.

1970s – 1980s:

In the 1970s, the metal panel industry primarily focused on commercial, industrial and agricultural buildings of 10,000 sq.ft. or smaller. In the 1980s, the industry continued to grow in response to customer and market needs. New coating technologies were introduced to provide better corrosion resistance, making metal buildings a more viable long-term option. Technological advances in wind loading for walls and wind uplift for roofs also addressed structural engineering concerns previously held.

1990s:

In the 1990s, metal building construction nearly doubled because metal had proven to be flexible, cost-efficient and time-saving. As a result. the industry expanded to include retail buildings and civil/service facilities, such as schools and hospitals. Emerging metal panel technology, such as snow load solutions, was beginning to be investigated and addressed. In particular, the advancement of computer technology helped create more robust design systems. This enabled manufacturers and contractors to quickly price and deliver detailed preliminary design drawings with greater efficiency and accuracy.

Early 2000s:

The first two decades of this century brought more diverse product and service offerings to the market. These included practical and aesthetic innovations like insulated metal panels (IMPs) as well as new roofing finishes. This decade also saw a new focus on metal building safety in response to dangerous California earthquakes. To help mitigate the risks, research into the structural implications of seismic activity was conducted, resulting in updated building standards. Customer requirements also drove energy performance optimization and engineering guidelines for tapered structural components, and new exterior finishes and styles for metal roof and wall panels were introduced. This included the use of horizontal instead of vertical siding systems and smooth-surface panel faces.

Today…and Beyond:

The dramatic and innovative industry advancements of the past have given way to the full and complete metal panel solutions for a wide range of building types—including unconventional ones like custom residences—that we enjoy today. Continued research, partnerships and collaboration are further driving industry expansion and diversification—a trend that shows no sign of slowing.

Choosing a metal panel color can feel daunting these days. With the number of available metal building colors having expanded from the usual white, tan and Galvalume to more than a couple of dozen options, where do you begin? What factors should influence your decision? Read on for recommendations on key questions to ask to help you make the best decision for both the desired aesthetic as well as longevity, durability and energy efficiency of your metal project.

What colors are metal products available in?

This is the most obvious consideration and can be answered with a simple search of the metal product manufacturer’s website. Authorized dealers also often have physical metal panel color charts, samples or chips from metal product manufacturers for in-person review. While metal panel color options used to be limited to standard stock colors like white, tan and Galvalume, today, many manufacturers are able to offer many more color options outright as well as additional custom colors. These new metal panel color options now include metallic paints, as well as ones with metal flecks that add sheen and sparkle, giving the panel color more depth and durability.

How can I be sure I’m getting the exact metal panel color I think I’m getting?

Upon request, most metal panel manufacturers are more than happy to provide actual color chips so you can see the exact color in person. While the chips on color charts are a close facsimile, getting color chips from the plant is ideal to ensure a perfect match. Additionally, you can view images of completed projects on the manufacturer’s website as seen in ABC’s Project Gallery. This section not only shows you photos of real-life building projects using our metal products so you can see how colors look in different combination and on different building types, but it also provides details on the products and colors used with additional resources to help you make your selection.

In addition, ABC’s Color Visualizer helps you envision your actual project before you even order your metal panels. You can upload your own photo or choose from our sample project photos to pick your ideal panel type and color. While it’s useful to review the manufacturer’s website and color visualization for project images and ideas, keep in mind that colors may look a bit different on your computer than they do in real life.

How to select the right color for optimal energy efficiency?

Cool metal roofs have been shown to be among the most sustainable and energy-efficient choices out there. They are designed to reflect more of the sun’s energy (and heat) back into the atmosphere to keep your building cooler and reduce your air-conditioning bills. (Read more about cool metal roofs in our blog post.)While lighter colors are generally the best option to optimize cooling effects, it should be stated that improved energy performance is a result of much more than just the roof’s color. The Cool Roof rating of paints and coating systems used by metal panel manufacturers are generally listed with the color choices on the manufacturer’s website. For detailed information, a great resource is the Cool Roof Rating Council, which maintains a products directory that lists solar reflectivity and thermal emissivity values for many roofing brands.

ABC offers the most sophisticated silicone polyester coating paint system in the industry. It offers optimum exterior protection and superior resistance to chemical corrosion and ultraviolet radiation, and most of our paint coatings are ENERGY STAR^® qualified.

Can I paint over my metal panels?

If you’re considering painting your metal panels, trim or accessories, you should first check with the metal product manufacturer to ensure you won’t be voiding any warranties. You can also ask the manufacturer about touch-up paint and the correct way to apply it if small corrections need to be made. If you do decide to completely re-paint your panels, it’s best to get the panel manufacturer’s recommendation on the best paint and application products/methods to use to ensure you don’t damage the steel underneath the paint.

What if my paint isn’t performing the way I expect it to?

Most manufacturers offer a limited warranty on their paint systems. Before you buy, be sure you understand the limits of the warranty. If you think your situation warrants a claim, take pictures of the product and send them to the manufacturer to start the process. Do not attempt to correct or cover any issues as this will likely void your warranty. The manufacturer will likely send someone out to look at your material and will keep you informed throughout the process.

Armed with the right questions, resources and, hopefully, color charts and samples, choosing a color for your new metal roof can be an exciting part of the process. Your job is to take the time to review the options to make the most practical and aesthetically appropriate decision.
