Product Overview
Galvanized steel coil, also called GI coil, is a low carbon steel coil coated with a protective zinc layer through a hot-dip galvanizing process. The zinc coating provides excellent corrosion resistance and long service life, making galvanized coils widely used in construction, เครื่องใช้ในบ้าน, automobiles and general fabrication. Our galvanized coils are produced from DX51D or SGCC grade base metal with zinc coating from Z80 to Z275, in regular, minimized or zero spangle finishes to suit different forming and painting applications.
