Sheet Metal Material Type

① Ordinary cold rolled sheet SPCC

SPCC refers to the continuous rolling of steel ingots into steel plate coils or sheets of required thickness through a cold rolling mill. The surface of SPCC lacks any protection and is easily oxidized when exposed to air, especially in humid environments where the oxidation rate accelerates and dark red rust appears. The surface needs to be painted, electroplated, or other protective measures when used.

② Galvanized steel plate SECC

The substrate of SECC is a general cold-rolled steel coil, which becomes an electrogalvanized product after undergoing degreasing, pickling, electroplating, and various post-treatment processes on a continuous electrogalvanizing production line. 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. It has great competitiveness and substitutability in the market of electronic products, home appliances, and furniture. For example, SECC is commonly used in computer chassis.

③ Hot dip galvanized steel sheet SGCC

Hot dip galvanized steel coil refers to the semi-finished product after hot rolling, pickling or cold rolling, which is cleaned, annealed, and immersed in a molten zinc bath at a temperature of about 460 ° C, to coat the steel sheet with a zinc layer, and then subjected to quenching, tempering, leveling, and chemical treatment. SGCC material is harder than SECC material, with poor ductility (avoiding deep drawing design), thicker zinc layer, and poor weldability.

④ Stainless steel SUS301

"The content of Cr (chromium) is lower than that of SUS304, and its corrosion resistance is poor. However, after cold processing, it can obtain good tensile force and hardness, and has good elasticity. It is mainly used for spring and EM prevention.".

⑤ Stainless steel SUS304

One of the most widely used stainless steels, it has higher corrosion and heat resistance than steel containing Cr (chromium) due to its Ni (nickel) content. It has excellent mechanical properties, no heat treatment hardening phenomenon, and no elasticity.
