Full Hard Galvanized Steel Coil G550

Full hard galvanized steel coil g550 refers to galvanized steel produced by cold-rolled unannealed strip steel and directly immersed in the plating bath without recrystallization treatment.

This kind of galvanized steel generally uses low-carbon cold-rolled steel plates with a carbon content of about 0.06% as raw materials, retaining the work hardening produced by cold rolling. The yield strength of the steel sheet is generally greater than 550MPa, and the tensile strength is generally greater than 570MPa. This kind of steel sheet is harder and less ductile, and the elongation rate generally does not exceed 7%.
