1. Cold-rolled plate SPCC, mainly with electroplating and baking paint parts, low cost, easy to form, material thickness ≤ 3.2mm.
2. Hot-rolled plate SHCC, material T ≥ 3.0mm, also with electroplating, baking paint parts, low cost, but difficult to form, mainly with flat parts.
3. galvanized sheet SECC, SGCC. SECC electrolytic sheet is divided into N material, P material, N material is mainly not for surface treatment, high cost, P material for spraying parts.
4. Copper; mainly used for conductive parts, its surface treatment is nickel-plated, chromium-plated, or no treatment, high cost.
5. Aluminum plate; generally with surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
6. Aluminum profile; cross-sectional structure of complex material, a large number of plug boxes used in a variety of. Surface treatment with aluminum plate.
7. Stainless steel; mainly used without any surface treatment, high cost.
