| Product Name | JAPAN NSC SECC-EG |
| Processability | Compared with GI and GA, although the adhesion of zinc coating is less, it has no heat effect on the manufacturing process, so it can form the same level of material properties and processability as Cr and HR of raw steel plate. |
|
Corrosion resistance |
The sacrificial anode effect of zinc battery is used to protect steel and form thin film when exposed in air to prevent corrosion. |
| Paintability | The surface is flat to ensure a good coating surface. In order to strengthen the adhesion and corrosion resistance of the coating, phosphate treatment was carried out. |
| Weldability | Compared with Cr steel, the contact area of galvanized steel becomes larger when it is pressurized, which is lack of conductivity. Therefore, the weldability is poor, but good spot welding and seam welding can be carried out by proper welding conditions and post-treatment. |
|
Industry application |
It is mainly used in construction, light industry, automobile, agriculture, animal husbandry and fishery, commerce and other industries; the construction industry is mainly used for manufacturing anti-corrosion industrial and civil building roof panels, roof grilles, etc.; the light industry industry is used to manufacture the shell of household appliances, civil chimney, kitchen and so on; the automobile industry is mainly used for manufacturing corrosion-resistant parts of automobiles; agriculture, animal husbandry and fishery are mainly used for grain storage and transportation, meat It is mainly used for material storage and transportation, packaging equipment, etc. |
