GulfLok is a 1 in. snap-lock, clip-less nailstrip standing seam panel whose nailstrip has slots for fasteners, so no clips or seaming tools are needed; Gulf Coast calls it its entry-level standing seam panel. It gives 12 in. and 16 in. net coverage in 24 and 26 gauge steel or 0.032 and 0.040 in. aluminum, including the OceanGuard coastal aluminum series, in flat, mini rib or striated relief, over 15/32 in. minimum plywood at a minimum slope of 3:12, and is also offered in Armored Coast 24 gauge coated steel at 16 in. coverage. The product page lists Miami-Dade approval 25-0415.03 and Florida Product Approvals FL34538.01-R3 (HVHZ) and FL33818.01-R5 (non-HVHZ). Gulf Coast's published UL statement says the fire classification under ASTM E108 and UL 790 is set by the complete roof assembly, including substrate and underlayment or barrier, and not by the panels alone.
