cold rolling coatings

Cold

Cold-rolled coils are supplied with surface quality А or B as per EN 10130, except for LA steel, which can have only А-type surface quality. Cold-rolled coils can be further used for metal coating by submerging the material into a metal bath, using electrolytic deposition, and/or applying organic and other types of coating. Get price
