galvanised steel coil
Galvanized steel coil represents a crucial advancement in metal protection technology, combining durability with versatile applications. This innovative product consists of steel sheets or strips that undergo a specialized coating process where zinc is applied to create a protective barrier. The galvanization process involves immersing the steel in molten zinc at temperatures around 860°F (460°C), forming a metallurgical bond that shields the base metal from corrosion. The resulting zinc coating not only provides exceptional resistance to rust and weathering but also offers sacrificial protection, meaning the zinc corrodes preferentially to protect the underlying steel. These coils are manufactured in various thicknesses and widths to meet diverse industrial requirements, with coating weights typically ranging from G30 to G235. The product's versatility makes it indispensable in construction, automotive manufacturing, and infrastructure development. Modern galvanized steel coils also feature advanced surface treatments that enhance paint adhesion and improve formability, making them ideal for both structural and aesthetic applications.
