Galvanized steel sheets are corrosion-resistant panels fabricated from cold-rolled or hot-rolled substrates, coated with zinc through hot-dip galvanizing or electro-galvanizing processes. Classified into hot-dip and electro-galvanized varieties, they offer exceptional rust resistance and corrosion protection. Featuring a smooth surface and excellent processability, these sheets support bending, stamping, and welding operations. As the core material for advanced processing applications including home appliances, automotive components, construction materials, hardware, ventilation ducts, and subsequent color coating or printing, they demonstrate broad applicability and high cost-effectiveness.
