Applications
Cold Rolled Full Hard (CRFH)
Galvanizing base material: Mainly used as the substrate for zinc, aluminum-zinc, or color coating lines.
Re-rolling processes: Suitable for cold re-rolling to achieve desired thickness.
Cold forming base: Used in applications requiring high hardness without the need for ductility.
Structural applications: Ideal for parts that demand high resistance to deformation.
Cold Rolled Annealing Coil (CRCA)
Stamping and deep drawing: Perfect for automotive, motorcycle, electronics, and home appliance industries due to excellent formability.
Electrical and electronics enclosures: Commonly used in electric panels, computer cases, control boxes.
Metal furniture manufacturing: For steel frames, cabinets, shelves, partitions requiring precision.
Consumer goods production: Applied in making washing machine covers, air conditioners, and other appliances that need smooth surfaces for painting.
