In the electronic products, home appliances and furniture market has great competitiveness and replaceability. After the continuous electro-galvanized production line is degreasing, pickling, electroplating, and various post-treatment processes, it becomes an electro-galvanized product.

5. Hot dip galvanized steel sheet SGCC

Hot-dip galvanized steel coil refers to the hot-rolled pickled or cold-rolled semi-finished products.Galvanized steel sheet SECC

The base material of SECC is a general cold-rolled steel coil.

3. It is mostly used for springs with shrapnel and anti-EMI. SECC not only has the mechanical properties and similar processability of ordinary cold rolled steel sheets, but also has superior corrosion resistance and decorative appearance. Leveling and chemical treatment. Stainless steel SUS301

The content of Cr (chromium) is lower than that of sheet metal welding manufacturers SUS304, and its corrosion resistance is poor.

4. Ordinary cold rolled sheet SPCC

SPCC refers to the continuous rolling of steel ingots into a coil or sheet steel of a desired thickness through a cold rolling mill. SPCC surface without any protection, exposed to the air can easily be oxidized, especially in the humid environment, the oxidation speed, the emergence of dark red rust, in the use of the surface to be sprayed, electroplated or other protection. For example, the computer chassis is commonly used SECC. It has excellent mechanical properties, no heat treatment hardening, and no elasticity. However, after cold working, it can obtain good tensile strength and hardness in stamping process, and its elasticity is good., and the steel sheet is plated with a zinc layer and then subjected to quenching and tempering. Stainless steel SUS304

One of the most widely used stainless steels is richer in corrosion resistance and heat resistance than Ni (nickel)-containing steels than Cr (chromium)-containing steels. SGCC material is harder than SECC material, poor in ductility (to avoid deep drawing design), thicker zinc layer, and poor weldability. After cleaning and annealing, it is immersed in a molten zinc bath at a temperature of about 460° C
