1. Galvanized steel plate SECC

The substrates of SECC are ordinary cold-rolled steel coils, which become electrogalvanized products after the continuous electroplating production line has been degreased, pickling, electroplating and various post-treatment processes. The SECC not only has the mechanical properties and approximate machinability of the general cold-rolled steel sheet, but also has the superior corrosion resistance and decorative appearance. In the electronic products, household appliances and furniture market with great competitiveness and substitution. For example, the SECC is commonly used in computer cases.

2. Ordinary cold-rolled sheet SPCC

SPCC refers to the continuous rolling of ingots through cold rolling mill into steel coil or sheet material with required thickness. (SPCC) surface without any protection, exposed to the air be oxidized easily, especially in the moist environment oxidation speed, a dark red rust, when use to spray paint, plating or other protective surface.

A hot dip galvanized steel plate SGCC

Hot dip galvanized steel coil is hot rolled after pickling and cold rolling of semi-finished products, after cleaning, annealing, immersion temperature of about 460 ° C in zinc melt trough, and make the sheet steel on zinc plating layer, then through conditioning leveling and chemical treatment. SGCC material is harder and less malleable than SECC material (avoid deep drawing design), zinc layer is thicker and less weldability.

4. Stainless steel SUS304

For one of the most widely used stainless steel containing Ni (Ni) reason than steel containing Cr (Cr) is full of corrosion resistance, heat resistance, has excellent mechanical performance, no heat treatment hardening phenomenon, no flexibility.

5. Stainless steel SUS301

The content of Cr (Cr) is lower than SUS304, and its corrosion resistance is poor. However, after cold processing, it can obtain good tensile force and hardness, good elasticity, and it is mostly used for springs of shrapnel and EMI prevention.
