Constructed of 29 & 26 gauge high tensile steel (to ASTM A792 Grade E, 80,000 minimum yield – 82,000 minimum tensile specifications), our ribbed panels are easy to install, sturdy, and weather tight. Resistance to dents, plus minimal expansion/contraction properties make this steel panel an excellent investment providing lasting protection and greater durability that will enhance all types of structural designs.
First, each panel is coated with Galvalume®, a patented aluminum-zinc alloy coating for extra protection. Panels are then bonderized and an OPTIMA Primer® is applied. The primer supplies flexibility and provides an excellent base for the final coat CERAM-A-STAR®, a ceramic pigmented silicone polyester, supplies strength, hardness and durability against the effects of sun, wind, rain, heat and cold. It is extremely resistant to mildew. No blistering, peeling and flaking either!
