Product Detail
S280GD is low-carbon steel, typically available as either cold-rolled or hot-rolled material. It’s coated with zinc through galvanizing, which boosts its resistance to corrosion. The steel contains elements like carbon, manganese, and silicon, which give it good strength and formability. S280GD also has solid stamping and bending properties, making it adaptable to various design needs.
This galvanized steel coil is widely used in the construction, automotive, appliance, and machinery sectors. It’s commonly found in roofing materials, wall panels, and window frames, as well as car body parts, appliance enclosures, and industrial equipment. The zinc coating helps prevent rust, which is especially useful in outdoor or damp environments. So, it’s a solid choice for applications where corrosion resistance is important, like outdoor structures and equipment exposed to tough conditions.
