Z40-Z275 Coated Galvanized Steel Coil Galvanized GI Sheet Mid Hard SGCC/DX51D/ASTMA36/JISG3302
Description:
The galvanized steel coil that most construction workers use is often found in roofing applications. There, it is used as a protective cover or barrier over ridges and valleys in the roof system. The coil is rolled out flat on the roof, and bent either over the top of a ridge or into the crease in a valley, to protect the seam in the roof’s sheeting from exposure to the elements. It also creates a watershed for the runoff of rain and melting snow or ice.
