Matterhorn Slate Metal Roofing Technical Info

  • Stronger than Steel

    Matterhorn® metal roofing starts with DDS high-performance G90 steel. Multiple layers of advanced polymer coatings are applied over the metal substrate. These coatings, along with the modern metallic alloys, provide outstanding corrosion resistance. The protective properties of these coatings create a self-healing surface. The result is metal roofing that is quite literally stronger than steel.

    Each panel is painted with a high-performance Valspar PVDF paint system, specifically engineered for fade resistance to last a lifetime.
