Cold rolled steel is also part of our product portfolio. Cold rolled steel is excellent for cold forming. The EN10130 standard product group assigned the grades DC01 to DC07.
EN 10130 sets forth the requirements for surface quality (А, B) and finishing (gloss b, semi-gloss g, matte m, rough r) along with other parameters of cold-rolled coils. Acceptable size and shape tolerances should correspond to EN 10131.

Commonly used in the steel industry, different from hot roll. Refer to the direct roll rolling at room temperature with a certain thickness and winding machine rolls into the whole volume of steel belt. Compared with hot-rolled coil, cold-rolled coil surface lightness, brightness and cleaness is high, but will have more stress, often in the annealing treatment after cold rolling.
For the final application, it is necessary to open the flat coils and cut the coils on the steel plate, so we open the flat coils and cut the coils to the steel plate as needed. To save cost of loading per container, loading in 20ft container, cut the length below 5800mm, generally as needed to cut up to 2440mm and 5800mm, the width is usually 1220mm and 1500mm. After cutting the steel coil into steel plate, we can make black paints on the surface of the plate to make the plate anti-rust.
