EG coil list

----------------------------------------- 

1. CR(Cold-rolled steel sheets) have good processability, with good flatness and excellent surface, are available with different thickness and width combinations; are mainly used to manufacture the high value-added products in automotive and appliance, beverage packaging, electronic, electrcial moor and building etc. The CR steel sheet include the oncoated steel steel , galvanzied steel sheet, tin plate and TFS, precoated steel sheet and electrical steel steel, etc.

2. EGI(Electrolytic Galvanized Steel Sheets) is produced by electrogildingzinc with cold-rolled steel sheets (CR) to enhance corrosion resistance, and while it has less zinc gilded than hot-dip galvanized steel sheets (GI), the gilded layer is even and the surface clean and maintains the mechanical characteristics of CRs because the gilding is done at a low temperature.

3. GL(Galvalume Steel Sheet_Aluminum-Zinc Alloy Coated Steel Sheets) are galvanized steel sheets with both zinc and aluminum, and is the ideal combination of anti-corrosion and alkali-resistance of zinc, and the durability, heat-resistance, and acid-resistance of aluminum. The galvanized layer is consisted of 55% of aluminum and 43.3% of zinc and 1.6% of silicon per weight, and 80% aluminum in terms of volume ratio, so while the advantages of aluminum is well preserved zinc prevents the risk of red rust on the surface, a weakness of aluminum, and the product combines the strengths of both materials.

4. GI(Hot-dip galvanized steel sheets) are produced by passing the full hard sheet which has undergone the acid washing process and rolling process through the zinc pot, thereby applying zinc film to the surface. GI has a thicker galvanized layer which has excellent anti-corrosion qualities, and is the type of steel sheet used most commonly.

5. GA(Galvannealed steel sheets) are produced by reheating the galvanized layer to spread the galvanized zinc and iron materials on the surface to re-coagulate a thin light gray layer of steel-iron alloy. The alloy layer contains about 10% of iron, and compared to pure zinc has less ionization and is stronger in terms of limited surface corrosion. GA is most commonly used in cars that require high-corrosion resistance after spot welding and stamping.
