Cold Rolled Steel Supplier - China

Cold rolling is the term for high-precision stamping substrates.

Through cold plastic deformation and controlled annealing processes, hot-rolled coils are transformed into "industrial-grade canvases" with thickness tolerance of ±0.01mm and surface roughness ranging from 0.4 to 3.2μm.

As the top base material for galvanizing and color coating, it can meets the most stringent forming and surface treatment requirements.

Core process

Hot-rolled raw material coil → Pickling (hydrochloric acid) →Cold rolling (five-stand continuous rolling) →Annealing (continuous/ induction) →Finishing (rolling and straightening) →Oil coating and winding As a premium cold rolled steel material supplier, Rosen provides a full range of cold rolled steel products, including cold-rolled steel sheet, cold rolled steel plate, and cold rolled steel coil, designed for industries with strict requirements on dimensional accuracy and surface quality.
