Hot-dipped galvanized steel coils are widely recognized for their outstanding corrosion resistance and versatility. The production process begins with cold-rolled steel, which undergoes cleaning and annealing in a reducing atmosphere before being immersed in molten zinc under controlled conditions. This results in a uniform, smooth zinc coating that adheres tightly to the steel surface. Even if the coating is scratched or the edges of the steel are exposed, the zinc layer continues to provide effective protection. Its enhanced corrosion resistance makes it a preferred choice for various industries, ensuring long-term durability and reliability.
We offer a range of galvanized options to meet specific customer needs:
- Spangled galvanized steel: Features a distinctive crystallized pattern, often preferred for its classic look.
- Spangle-free galvanized steel: Provides a smooth, uniform finish suitable for applications requiring a sleek surface.
- Zinc-Aluminum Coated Steel: Combines enhanced corrosion protection with a refined appearance.
Our galvanized steel sheets & coils are treated primarily with chrome-based passivation, which is known for its superior corrosion resistance. Additionally, we offer:
- Chrome-free passivation for environmentally sensitive applications.
- Hexavalent chromium-free passivation, aligning with global environmental standards.
- Anti-fingerprint film for enhanced surface protection.
For customers requiring pre-painted steel, we enhance the galvanized substrate with a skin-pass process, improving surface smoothness and ensuring excellent paint adhesion.
