GI Steel Coil
GI sheet coils, also known as galvanized steel coils, are steel sheets coated with a layer of zinc through a continuous hot-dip galvanizing process. The zinc coating provides effective protection against corrosion, significantly extending the service life of the steel in humid, outdoor, or industrial environments. With a combination of structural strength and corrosion resistance, GI sheet coils are widely used in construction, manufacturing, and infrastructure projects.
These coils offer excellent formability, stable mechanical properties, and consistent coating quality, making them suitable for various fabrication processes such as roll forming, bending, stamping, and profiling. GI sheet coils are commonly applied in roofing sheets, wall panels, HVAC ducting, electrical cabinets, household appliances, agricultural equipment, and light structural components. The zinc layer also provides a clean and uniform surface, making the material suitable for further painting or coating when additional protection or decorative appearance is required.
Kennen Steel supplies GI sheet coils in a wide range of thicknesses, widths, and zinc coating weights to meet diverse project and manufacturing requirements. Supported by stable mill partnerships and efficient supply chains, Kennen Steel can arrange customized specifications and coordinate additional processing services when needed. Coils can be slit, cut to length, or surface-treated according to customer requirements, ensuring efficient downstream fabrication and reliable performance in various industrial applications.
