How to Choose the Metal That is Best for Your Metal Roofing System
Metal roofing panels are available in steel, aluminum and copper. These metals all offer high-performing durability and longevity, but each has its own unique benefits.
Find the Perfect Finish for Your Metal Roofing Project
For the life of your metal panels, the coating system, or painted surface, will be exposed to many environmental elements, including harsh UV rays, acid rain, dirt, etc. When shopping for metal roofing, it’s important to understand how the coating system you choose will stand up to these tough conditions and add to the longevity of your metal roofing system.
Metal panel coatings are made of resin, pigment, solvents and additives. These elements are combined and applied to metal prior to the metal panel–forming process to ensure uniform color, sheen and thickness of the coating. The primary difference between all the metal roofing coating products available today is the type of resin used to bind the coating elements together. Extreme Metal Fabricators exclusively uses the industry’s leading coating systems: Kynar 500®, a polyvinylidene fluoride (PVDF) coating, and Valspar’s Weather XL®, silicone modified polyester based coating known as SMP.
