S280GD Galvanized Steel price
The price of S280GD+Z galvanized steel coil depends on the material, specification, surface treatment and supplier, the minimum order price is 650-850USD per ton, the thicker the zinc layer, the higher the price. Meanwhile, the price for different surface effects such as zero zinc, small zinc, fingerprint resistance, chromate passivation, etc. is also different, if you need, you can leave a message to let us know, and we will give you a free quote.
S280GD Galvanized Steel Advantages and Applications
S280GD galvanized steel is designed for building construction, heavy equipment and transportation fabrication, offering excellent structural support, good weldability and formability.
Benefits
- High Strength: 280 MPa yield strength is in the medium to high strength class of structural galvanized steel to support critical structural components.
- Lightweight: Reduced material usage reduces the weight of the building or product while meeting load-carrying requirements.
- Advanced Corrosion Protection: Coating thicknesses can be selected depending on the application to withstand harsh industrial environments.
- Optimized formability: Maintains the ability to bend/stamp complex designs and can be used as a raw material for a wide range of complex shapes.
- Aesthetically pleasing and uniform: Smooth surface with zinc spangle and support for chromic acid passivation, oiling and fingerprint resistance.
Applications
- Construction: Industrial roofs, warehouse frames, structural supports (C-beam, Z-beam or light steel keel raw materials), roofs and walls of large buildings such as stadiums.
- Transportation: truck trailers (doors, hoods, chassis components), cargo containers, vehicle reinforcement.
- Heavy equipment : Agricultural machinery, conveyor systems, storage racks.
- Agriculture : Structures for barns, livestock sheds, etc.
- Energy infrastructure : Installation systems for solar farms, transformer housings, transmission towers, distribution boxes.
