1. Cold-rolled plate SPCC, mainly with electroplating and baking paint parts, low cost, easy to form, material thickness Less than or equal to 3.2mm.
2. Hot rolled plate SHCC, material T Greater than or equal to 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 plate is divided into N material, P material, N material is mainly not surface treatment, high cost, P material is used for spraying parts.
4. Copper; Mainly with conductive materials, its surface treatment is nickel plating, chrome plating, or no treatment, high cost.
5. Aluminum plate; Generally, surface chromate (J11-A), oxidation (conductive oxidation, chemical oxidation), high cost, silver plating, nickel plating.
6. Aluminum profile; Materials with complex cross-sectional structures are widely used in various inserts. The surface treatment is the same as that of aluminum plate.
7. Stainless steel; It is mainly used without any surface treatment, and the cost is high.
