Q: What are the common thicknesses and dimensions of SPCC?
A: Sheet metal: 0.5-3.0mm × 1250mm × 2440mm; Strip metal: 0.3-2.5mm × 355-1500mm, custom sizes up to 2000mm wide and 6000mm long are available.
Q: What are the surface quality grades of SPCC?
A: Common grades are FB (higher grade) and FC (standard grade); FB allows for slight pitting/scratches, FC accepts a small number of defects.
Q: What are the surface treatment methods for SPCC?
A: Natural finish (with anti-rust oil), phosphating, electrophoresis, spraying, electroplating (zinc/zinc-iron alloy) to improve corrosion resistance.
Q: How to prevent oxidation and rust on the surface of SPCC?
A: Store in a moisture-proof environment, apply anti-rust oil, and use sealed packaging; passivate or paint promptly after processing, and avoid exposure to humid environments.
Q: What are the dimensional tolerances for SPCC? A: Thickness tolerance ±0.02-±0.10mm (according to accuracy grade); width/length tolerance ±2-±5mm; flatness ≤5mm/m.
