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.
Structural steel is widely used in the fields of construction, bridges, machinery manufacturing, etc. S280GD+Z, S350GD+Z and S450GD+Z are three different types of high-strength structural steels, which differ in hardness, yield strength, tensile strength, etc., so the prices will also be different.
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.
Galvanized square pipe refers to galvanized square pipe, which is a steel pipe with a square cross-section and the surface is galvanized to enhance corrosion resistance.
Hot galvanized steel pipe refers to hot-dip galvanized steel pipe, which is galvanized on the surface of ordinary steel pipe to form a zinc layer, which can protect the steel pipe from corrosion and extend the service life of the steel pipe.
Q235B and Q355B galvanized round pipes are two commonly used types of steel, which differ in composition, mechanical properties and application areas.
