Cold rolled steel has a much smoother appearance and is stronger than hot rolled steel. It is the next step along the line of flat-rolled steel products.
The process of creating cold rolled steel begins with hot rolled P&O. The hot rolled P&O is sent through a cold reduction process which creates a thinner thickness and a harder surface. This also makes the steel difficult to form.
The steel is then sent through an annealing process which consists of a heat treatment to increase ductility. After annealing the material is kept covered to prevent oxidization and allow for the breakdown of oils that may still be present.
To assist with the surface finish and flatness of the material it undergoes temper rolling, or cold rolling the material with low reduction.
The end result is a cleaner, finer surface finish metal.

Metal furniture, desks, filing cabinets, shelves, tables, chairs, motorcycle exhaust pipes, computer cabinet and hardware, all home appliances and components, shelving, lighting fixtures, hinges, tubing, steel drums, lawn mowers, electronic cabinetry, lighting fixtures, water heaters, metal containers, and a variety of construction related products.
Cold Rolled Steels can be used to produce parts containing simple bends to parts with extreme deep drawing requirements depending on the grade and mechanical properties selected. Cold rolled sheet metal can be readily welded and is suitable for painting applications when the surface has been well cleaned.
