DX51D: Usually used for general purposes, with lower tensile strength. DX52D: Slightly higher tensile strength than DX51D, suitable for applications with slightly higher strength requirements. DX53D: Has higher tensile strength, suitable for more demanding application environments. DX54D: Is the highest grade among these, with the highest tensile strength, suitable for industrial applications with high strength requirements
Hot-dip galvanized steel is coated with pure zinc to provide excellent corrosion protection. This coating can provide continuous protection in the atmosphere for decades, reducing the cost of maintaining and replacing steel.
SGHC and SGCC are the same hot-dip galvanized steel sheets, generally processed according to JIS G 3302, but it is made from hot-rolled original sheets, and the applied thickness is 1.6mm to 6.0mm, which is thicker than SGCC. It also uses the hot-dip galvanizing process and has the high corrosion resistance brought by hot-dip galvanizing. The zinc layer can effectively protect the steel sheet and prevent rust and corrosion.
DC51D, DC52D, DC53D, DC54D+Z are different grades of galvanized steel sheets. Galvanized steel sheets are made by dipping thin steel sheets into a molten zinc bath to adhere a layer of zinc to the surface. They are mainly produced by continuous galvanizing process, that is, the rolled steel sheets are continuously dipped into a molten zinc bath to make galvanized steel sheets.
The hot-dip galvanizing process forms a zinc coating on the surface of the steel strip, which can effectively isolate the steel from the external environment, prevent the steel from rusting and corrosion, and greatly extend the service life of the steel strip. It is suitable for various harsh industrial and outdoor environments.
The dense protective layer and electrochemical sacrificial anti-corrosion effect form an excellent anti-corrosion layer to protect steel. Long-term anti-corrosion effect, no maintenance required, is the most economical long-term anti-corrosion method. Iron and zinc react to form an alloy, strong adhesion, impact resistance, friction and not easy to peel off.
