Over the past few years corrugated profiles have become increasingly popular in architectural metal wall panel applications. What was once a product used primarily in industrial applications has evolved to where there are many options for a designer to choose from for architectural uses. These panels can be intermixed with many types of metal panels or other products, resulting in a classy and elegant appearance.
In doing so, it is important to understand the two types of corrugated panels.
Face-Fastened Panels
The first type of corrugated panel is the face fastened panel. These can be considered the first generation of corrugated panels. A benefit of a face fastened panel is the panel can be made in a larger profile (panel width) that can range from 24 to 36 inches by various lengths, depending on the profile. Face fastened panels have their place as long as the designer is comfortable with a visible fastener. All of these products are typically roll formed, which does not allow for customization of the profile. However, there are a large number of profile choices available from various manufacturers. In most cases, face fastened panels are manufactured using lighter gauge prefinished steel.
Concealed Fastener Panels
The second type of corrugated panel is the concealed fastener panel. These panels are typically fastened using clips to attach the panel or with an integrated clip that is part of the panel. Both of these fastening methods are usually not visible when looking at the face of the panel and are incredibly effective while still easy to install. Both options also allow the panel to expand and contract to reduce chances of oil canning. These panel profiles typically range from ten to twenty inches wide depending on the profile.
Although most of these profiles are supplied in light gauge prefinished aluminum and steel, there are some other options to consider. Manufacturers also offer the concealed fastener panels in heavier gauge aluminum, which is more durable, for higher traffic areas. The heavier gauge aluminum is generally post painted which allows limitless custom color options. Heavier gauges are manufactured without using a roll former, which allows a designer the option to customize the profile design. Additionally, stainless steel panels can also be corrugated where at one time it was not available as it could damage tooling.
Installation Considerations
When installing either panel type for an architectural wall application, it is recommended that a weather barrier be used behind the panel system. Typically installing to either a wood substrate or utilizing steel sub-girts works well with any of the panel options available. As always, proper flashing of the systems are key, and the installer needs to following the manufacturer’s recommended methodology to achieve good results.
In conclusion
The many corrugated panel options available offer designers a wide variety of choices when incorporating corrugated profiles in their projects. The wide variety of color and profile choices allows the designer to pick a product that will be elegant, sustainable and perform well on any structure.
