SGCC galvanized steel coil is a common hot dip galvanized steel coil product. SGCC represents the variety of its materials and is also one of the rating standards for steel. Hot dip galvanized steel coils are steel products that are immersed in molten zinc and undergo a series of treatment processes to form a zinc coating on their surface.
DX51D refers to the coating quality of the galvanized steel coil. The “D” represents the deep drawing quality, indicating that the steel is suitable for deep drawing applications. The “X” indicates that the steel is continuous hot-dip galvanized. The number “51” indicates the minimum yield strength of the steel, which is 51,000 psi or 355 MPa.
Galvanized steel coil is a type of steel coil coated with a layer of zinc to enhance its corrosion resistance. The Hot-dip galvanization process forms a durable and protective zinc coating on the steel surface, which is suitable for applications in humid and corrosive environments
