CRCA Cold Rolled Black Annealed Steel Coil

Black annealed cold rolled crca steel coils

CRCA Cold rolled black annealed is a steel coil manufacturing process. If the cold rolled steel coil is heated to annealing temperature, the surface color turns black due to high temperature contact with air, so it is called black annealed cold rolled steel coil. Its surface has not been polished, so it is black. The black surface is not so bright. It’s a little black, but it’s a little more straight on the surface, and it’s used in some places where the requirements are not very strict.
