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.
Galvanized coil is a kind of steel coil that has been galvanized. Galvanizing means coating the steel with a layer of zinc to improve its corrosion resistance. This treatment not only increases the service life of the steel, but also improves its aesthetics and functionality.
The cross-sectional shape of H section steel is economical and reasonable, with good mechanical properties. When rolled, the extension of each point on the cross-section is relatively uniform and the internal stress is small. Compared with ordinary I-shaped steel, it has the advantages of large cross-sectional modulus, light weight, and metal saving, which can reduce the building structure by 30-40%.
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.
Galvanized angle steel is a metal product with excellent performance and durability. Its corrosion resistance, high strength, easy installation, beautiful and durable features make it widely used in many fields.
