Substrates and Coatings
Galvalume Steel Substrate
Galvalume substrates combine the perfect blend of zinc and aluminum for maximum corrosion resistance and long-term performance. Years of field testing and research indicate that Galvalume substrates are superior to galvanized.
In fact, Galvalume is the only substrate that carries a warranty by steel mills.
Kynar 500® Paint System
MESA is only available with the industry’s highest quality coating - Kynar 500. Decades of service life and testing prove that Kynar 500 coatings offer the industry’s best resistance to fade and chalk. With Kynar 500, your projects will retain their new building sparkle year-after-year.
Gloss retention is one way panels retain their long-term curb appeal. As seen on this graph Kynar 500 coatings have superior gloss retention compared to other coating systems. The end result is that new building appearance year-after-year. 
This is an actual project in Ohio where siliconized polyester and Kynar 500 panels were shipped and utilized on the same roof. Initially, the panels were identical colors. Five years later, note how badly the siliconized polyester coating faded and chalked.
