Metal Roof and Siding Substrates

The most popular steel substrates in the metal roofing and siding industry are Galvanized and Galvalume. Galvanized substrates are coated with a zinc alloy, while Galvalume substrates are coated with an alloy of zinc plus aluminum. Both Galvalume and Galvanized are good substrates for metal panels.

Metal Roof and Siding Coatings

The coating, or paint system for metal panels is just as important as the substrate. For the life of the panel, the surface, or coating, will be continuously exposed to environmental elements.

Over time, these environmental conditions, especially the sun, can degrade the coating resulting in panel fade and chalk. Therefore, choosing the right coating that can combat Mother Nature's elements is critical to a long lifespan for your metal roofing and siding.
