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.
| Zinc Coating (Spangle) | Regular spangle (SR) | Key applications include: Construction:Used in residential building projects,roofing,structural components,ceiling panels,balconies,window frames,storage units,garage doors,heating systems,rain gutters,and HVAC ductwork. Furniture Industry:Suitable for wardrobes,desks,bookshelves,cabinets,counters,signage,and decorative lamp covers. Transportation Sector:Ideal for car bodies,trailers,containers,highway guardrails,and ship partitions. Home Appliances:Frequently used in refrigerators,washing machines,air conditioners,microwaves,vending machines,and range hoods. Miscellaneous Uses:Advertising boards,meters,speaker casings,and waste bins. |
| Spangle-free (F) | Ideal for painted surfaces requiring excellent adhesion. | |
| Galfan zinc-aluminum coated (ZA) | Commonly used as a substrate for pre-painted products,requiring surface coating for enhanced protection and performance. | |
| Galvalume aluminium-zinc coated (AZ) | Suitable for pre-painted steel and electronic cabinets. | |
| Surface Treatment | Chromium passivation (C) | Recommended for environments requiring high corrosion resistance. |
| Oiling (O) | Suitable to prevent oxidation during storage,transportation,and processing,ensuring product integrity and performance. | |
| Trivalent chromium passivation (C3) | Applied in environments requiring enhanced corrosion protection while adhering to environmentally friendly standards. | |
| Chrome-free passivation (C5) | Eco-friendly solution for areas with strict environmental requirements. | |
| Anti-fingerprint film (AF) | Designed for products where a clean,smudge-free surface is crucial,such as visible appliance panels. | |
| Classifications of Steel | Commercial quality (CQ) | Ideal for simple mechanical processing. Materials with thicknesses below 0.70mm can be used for mechanical interlocking processes,while those above 0.70mm are suitable for 90° bending. |
| Drawing quality (DQ) | Ideal for manufacturing products with basic shapes,making it suitable for mechanical interlocking processes. | |
| Structural quality (SQ) | Tailored for load-bearing applications,ensuring smooth curvature transitions during bending to enhance durability. |
