S220GD+ZF hot-dip galvanized steel is a hot-dip galvanized steel, where "S220GD" represents its yield strength grade of 220MPa, while "+ZF" may indicate a specific galvanizing process or surface treatment. The steel is covered with a zinc layer to protect it from corrosion.
S220GD+ZF hot dip galvanized steel features
High strength and corrosion resistance: S220GD+ZF galvanized steel after galvanized treatment, the surface is covered with a dense zinc layer, effectively improving the corrosion resistance and rust resistance of the material. Its yield strength can reach 220MPa, with good strength and stiffness.
Light and easy to process: Compared with traditional steel materials, S220GD+ZF galvanized steel has a lighter weight, the weight of the same volume is only about 1/3 of steel. This makes it more convenient during transportation and installation, reducing construction costs. At the same time, the material also has good processing performance, can be processed by cutting, drilling, bending and other ways, and has strong adaptability.
Beautiful and generous: The surface of S220GD+ZF 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.
S220GD+ZF hot dip galvanized steel is mainly composed of carbon, silicon, manganese, phosphorus, sulfur and other elements, the specific chemical composition may vary depending on the manufacturer and process. However, in general, its carbon content (C) usually does not exceed 0.13%, silicon content (Si) has no specific value, manganese content (Mn) does not exceed 0.50%, phosphorus content (P) and sulfur content (S) do not exceed 0.035%.
Mechanical properties of S220GD+ZF hot dip galvanized steel
Yield strength: ≥220MPa
Tensile strength: ≥300MPa
Elongation after breaking: ≥18% (or possibly 20% according to reference articles 3 and 4)
S220GD+ZF hot dip galvanized steel application range
Construction field: S220GD+ZF galvanized steel is widely used in various buildings and structures structural support, roof and wall reinforcement, door and window manufacturing and other aspects. Its excellent strength, corrosion resistance and beautiful atmosphere have been favored by the majority of builders and designers.
Bridge engineering: In bridge engineering, S220GD+ZF galvanized steel has the advantages of light weight, high strength and corrosion resistance, and is widely used in the manufacture of bridge load-bearing components and connectors.
Pipeline engineering: In pipeline engineering, S220GD+ZF galvanized steel is used in the manufacture of various water supply and drainage pipelines, gas pipelines, etc. Its corrosion resistance and strength can ensure that the pipeline does not rust and damage during long-term use.
Other fields: such as power engineering wire bracket, transformer base, etc., as well as automobiles, home appliances and other fields are also widely used.
