Strength and Beauty Meets Durability

Tough and beautiful, our ULTRAMAX 1 3⁄4-inch, snap-lock, panel system stands out from the rest. The seam is bolder and stronger, thanks to the robust seam thickness and the concealed fastener clip system. With continuous seam transitions, this versatile panel system creates pure clean lines, while delivering the ultimate in strength and wind resistance. ULTRAMAX is the choice for upscale commercial or residential projects that require top performance.
