Product overview
Cold-rolled steel strip

Kwong-Wai, good friend of cold-rolled steel strip is below the room temperature of hot rolled coil and as a raw material, in rolling conditions of recrystallization, including rolls, pickled after cold rolling mill rolling thickness, usually without intermediate annealing, each rack (or through) under pressure, power and speed rolling mill commitments, taking into account the yield and quality of manufacture.
Lubrication technology in the production of one of the most important factors: Lubrication and cooling effect.

Generally have good cooling performance emulsion, good lubrication properties when rolling thin or hard metal solid oil lubricant,
Our cold-rolled steel strip has the following characteristics:
High straightness,
Natural light smooth surface,
Surface clean and bright, without burrs, rust, bunkers and fracture
Easy to dispose of the coating,

Also has high-performance and degradation characteristics of low yield point,

Kwong-Wai, good friend cold-rolled steel coils are very versatile, and is mainly used in automotive, printing drum, construction, building materials, bicycles and other industries.
