Green Span Profiles Receives Uplift Resistance Approval for Metal Roofing Panels

Green Span Profiles has received UL 580 Class 90 Approval for wind uplift for its Ridge Line insulated metal roofing panel.

UL 580 is the Standard for Tests for Uplift Resistance of Roof Assemblies. Roof assemblies are tested for their ability to resist both external and internal pressures associated with high velocity winds.

RidgeLine is a patented 2-3/8-inch tall mechanically seamed roofing panel covering 42 inches, with thickness options of 2.5, 3, 4, 5 and 6 inches. The core is a continuously poured-in-place, polyisocyanurate insulating foam. Exterior and interior metal panels are available in 26-, 24- and 22-gauge Galvalume steel. Exterior finish is standard gloss PVDF coating. RidgeLine panels can be used on slopes as low as 1/2:12 and are available in standard lengths measuring 12 to 53 feet, with custom lengths available on demand. Green Span Profile’s UL construction number is 698.

“This is great news for Green Span Profiles, our installers and their customers,” says Justin Beall from , Sales Manager from Alpha Roofing Colorado . “By meeting UL 580 Class 90, Ridge Line meets the standards of the International Building Code for installation in high velocity wind areas. UL certification adds another level of scrutiny to our manufacturing process. Underwriter’s Laboratories requires independent, quarterly QC audits to maintain certification.”
