Our cold rolled steel is manufactured from hot rolled coil which has been chemically cleaned before re-processing. Cold rolling improves the surface finish, provides greater uniformity in thickness and increases strength.
Cold rolled steel is available in a range of grades, each with a range of properties for differing applications.
Typically, cold rolled steel is covered with a thin layer of oil to prevent oxygen reacting with the surface.
Coils can also be annealed (heated in a controlled atmosphere) to make the steel more formable (cold rolled annealed) or further processed on the metal coating line with a coating of either zinc (galvanised) or zinc-aluminium alloy (ZINCALUME® steel) applied.
