Product details
Cold-rolled steel is also part of our product portfolio. Cold-rolled steel is an excellent cold-rolled formation. The Standard Product Group in10130 assigns degrees dc01 to dc07.
In 10130, surface quality requirements are specified (A, Cold-laminated coil finish (brightness B, semi-gloss G, matte M, roughness r) and other parameters. Acceptable dimension and shape tolerances will conform to the standard in 10131.

It is commonly used in the steel industry, unlike hot rolling. The utility model refers to a strip of steel rolled into an entire roll by a winding machine of a certain thickness at room temperature. Compared to the hot-rolled coil, the cold-rolled coil surface has higher brightness and finish, but will produce increased stress, often after cold annealing.
