Product details
Cold rolled steel is a type of steel that has undergone additional processing after being hot rolled. The process includes cooling the hot rolled steel at room temperature, followed by annealing and/or temper rolling. This results in steel with closer dimensional tolerances and improved surface finishes.

Cold-rolled steel sheets and strips are available in full-hard, half-hard, quarter-hard and skin-rolled conditions. Among these conditions, full-hard rolling reduces the thickness almost 50%, while the others are thicker. Skin-rolled steel stock is commonly used in subsequent cold-working methods where good ductility is required.

Other shapes can be cold-rolled if the cross-section is relatively uniform and the transverse dimension is relatively small. Cold-rolled shapes are processed in a series of shaping operations. This is usually done along the lines of sizing, breakdown, roughing, semi-roughing, semi-finishing and finishing.

Cold-rolled steel is used for a variety of products ranging from home appliances like refrigerators and washing machines to industrial machinery, architectural components, automobiles and a variety of construction-related products. Cold-rolled steel is an indispensable material in our modern society. Cold-rolled steel exhibits corrosion resistant properties. Smoother surface finishes are more corrosion resistant.
