S220GD+Z galvanized steel features
High strength and corrosion resistance: After being galvanized, S220GD+Z galvanized steel is covered with a dense zinc layer, which effectively improves the corrosion resistance and rust resistance of the material. At the same time, its yield strength can reach 220MPa, and its strength and stiffness are very high, making this material still maintain good stability and durability in a variety of harsh environments.
Light and easy to process: Compared with traditional steel materials, S220GD+Z galvanized steel has a lighter weight, the weight of the same volume is only about 1/3 of steel. This feature makes S220GD+Z galvanized steel more convenient during transportation and installation, reducing construction costs. In addition, the material also has good processing properties, can be processed by cutting, drilling, bending and other ways, and has strong adaptability.
Beautiful and generous: The surface of S220GD+Z galvanized steel is covered with a layer of zinc layer, the surface is smooth, not easy to rust, and has a good beautiful and generous effect. In the field of architecture and decoration, this material is often used to make beautiful doors, Windows, railings and so on.
S220GD+Z galvanized steel chemical composition
The chemical composition of S220GD+Z galvanized steel mainly includes carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S) and other elements. The specific content is as follows:
Element content range
Carbon (C) 0.06% ~ 0.15%
Silicon (Si) 0.03% ~ 0.50%
Manganese (Mn) 1.00% ~ 2.00%
Phosphorus (P) ≤0.040%
Sulfur (S) ≤0.035%
The reasonable configuration of these elements makes the S220GD+Z material achieve an ideal balance in performance.
S220GD+Z galvanized steel delivery status
The delivery status of S220GD+Z galvanized steel is usually galvanized after hot rolling. The galvanizing process includes hot dip galvanizing, in which steel is immersed in a molten zinc solution at high temperatures so that a uniform zinc layer is formed on the surface of the steel. This treatment not only improves the corrosion resistance of the steel, but also increases its aesthetics.
