Product Detail
S320GD is a high-strength hot-dip galvanized low-carbon steel. The zinc coating on its surface provides added corrosion resistance and extends its lifespan. It contains elements like iron, carbon, manganese, and silicon, which give it good strength and formability.
The steel is easy to work with — it can be cut, bent, and stamped into various shapes, making it adaptable for different design and manufacturing needs. This flexibility makes it useful across a range of industries.
S320GD galvanized steel sheet/plate is commonly used in construction, automotive, and appliance sectors, especially for components exposed to harsh environments, like exterior walls, roofs, and car bodies. The zinc coating protects against moisture, acid rain, and other corrosive elements, making it ideal for areas with high humidity or fluctuating temperatures. It’s also used in light industrial machinery and outdoor equipment.
