Galvanized Steel Coil is used cold rolled steel coil as substrates by a continuous hot-dip process. This method tightly adheres the coating to the steel with an iron-zinc alloy bonding layer formed by a diffusion process while the heated steel strip is in contact with the molten zinc. One of the drawbacks of Galvanized is that if the Zinc coating is scratched off the steel, the Steel is left unprotected, and is subject to failure. It has excellent corrosion resistance, paintability, and workability due to zinc’s characteristics.
| Surface treatment type | Code | Feature |
|---|---|---|
| Chromic acid treatment | C | Good corrosion resistance, suitable for bare state |
| Chromic acid treatment + oiling | S | Good corrosion resistance |
| Phosphoric acid treatment (including sealing treatment) | P | A certain degree of corrosion resistance, good paint performance |
| Phosphoric acid treatment (including sealing treatment) + oiling | Q | It has certain corrosion resistance, good paint performance, and prevents rust during transportation and storage |
| Phosphoric acid treatment (excluding sealing treatment) | T | A certain degree of corrosion resistance, good paint performance |
| Phosphoric acid treatment (excluding sealing treatment) + oiling | V | Have certain corrosion resistance, good paint performance, and prevent rust |
| Oiled | O | Prevent rust during transportation and storage |
| No treatment | M | Suitable for immediate painting |
Chromate treatment of galvanized steel coils is also called passivation treatment. Through passivation treatment, the surface structure and gloss of the galvanized layer can be improved, the corrosion resistance and service life of the galvanized layer can be improved, and the bonding force of the coating and the base metal can be improved.
The purpose of oiling galvanized steel coils is a protective layer is formed on the surface of the steel coil to prevent the surface from rusting.
Commercial Steel is a low-carbon cold-formed steel, such as galvanized steel roof forming
Requires higher drawability than Commercial Steel, such as for lamp cover forming
Low carbon steel for cold forming (DX51D – DX54D)
Structural Steels (S220GD – S350GD)
S220GD,S250GD,S280GD,S320GD,S350GD
Use structural steel for high load-bearing capacity, with a yield strength of 220-350
