Cold Rolled Coils

Cold rolled steel coil is hot rolled steel coil that has undergone pickling, cold rolling, annealing, tempering and skin-passed processes. Cold rolled steel products are thinner and can be cut to size with greater accuracy than hot rolled steel. Characteristics and Applications: 1. Fine and smooth surface:  a good choice for products that require high quality surface appearance, such as sheet metal for automobiles and home appliances.

2. Various and uniform mechanical property: 
 CQS used for drum body, CQ1 for pipe,SPCE(deep drawing quality) for automobile parts which requires strict shaping operations, and high strength steel used for various kinds of structural parts.

3. Good ductility and malleability: 
    enhancing surface hardness and abrasiveness through 
carburization and nitriding making the surface hard and durable. Examples are S35CM(medium-high carbon steel) used in chains and SPP (heat resistant and low carbon steel) used in enamel treatments. Cold-rolled steel can be galvanized, electro-galvanized or laminated, therefore has a wide range of applications.
