Galvanized steel sheet
Galvanized steel sheet is a type of steel that has been coated with a layer of zinc through a chemical process. This zinc coating provides several key benefits, making it a popular choice in various industries.

These steels belong to the galvanized series, where DX51D, DX52D, DX53D and DX54D represent different strength grades, while +Z means the surface is hot-dip galvanized 76. The galvanized layer provides good corrosion resistance and is suitable for a variety of outdoor and indoor building structures.
The galvanized layer can effectively prevent oxygen from contacting the metal surface, thereby slowing down the oxidation rate of the metal and improving the corrosion resistance of the galvanized sheet, so that it can be used for a long time in harsh environments without rusting, reducing the frequency of maintenance and replacement.
Hot-dip galvanized steel sheet not only has high strength and hardness, can resist extrusion and deformation of external forces, but also has good plasticity and weldability, which is convenient for processing and assembly. In addition, it also has good reflective properties, can reduce the absorption of solar radiation, reduce indoor temperature, and improve energy efficiency.
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.
Q355B galvanized steel sheet has a tensile strength of up to 400-550MPa and a yield strength of 280-420MPa, which can maintain high strength and stability under heavy loads and complex working conditions. With an elongation of 21-29%, it can exhibit good plastic deformation ability when subjected to external forces, absorb more energy, and protect the structure from damage.
