The US-200 and US-210A are our most robust and tested structural standing seam systems. These standing seam systems are popular for military, large commercial, extreme weather conditions and low-slope applications. The U.S. Metals manufactured US-200 and US-210A are mechanically seamed in single or double locked configurations. The US-200 and US-210A offer excellent wind uplift resistance and are UL rated class 90 wind uplift and ASTM tested for wind uplift, air infiltration and water infiltration. The US-200 and US-210A are excellent roofing systems over wood and metal decking and over open purlins.
