Product Detail
S220GD galvanized steel coil is a low-carbon steel made primarily of iron, carbon, manganese, and silicon, with a yield strength of around 220 MPa. It offers good formability and decent corrosion resistance. The steel undergoes hot-dip galvanizing, which improves its corrosion resistance and overall durability, making it a good choice for more humid or harsh environments.
The surface is usually smooth and even, although it might have a light oxide layer or zinc flowers. It’s also known for its good weldability and formability, so it works well for processes like stamping and stretching. The zinc coating thickness and surface treatment can be adjusted based on specific needs.
This steel coil is commonly used in industries like construction, automotive, and home appliances, with applications in parts like vehicle body components, roof panels, wall panels, and appliance housings.
