Cold rolled steel is essentially hot rolled steel that has been through further processing. Once hot rolled steel has cooled, it is then re-rolled at room temperature to achieve more exact dimensions and better surface qualities.

Hot rolled steel is steel that has been roll-pressed at very high temperatures—over 1,700˚F, which is above the re-crystallization temperature for most steels. This makes the steel easier to form, and resulting in products that are easier to work with.

SPCC steel is produced by subjecting hot rolled steel to a cold rolling process, which not only improves its surface finish but also enhances its mechanical properties.

DC01, DC02, DC03, DC04 are steel grades of European standard DIN EN 10130, 10209 and DIN 1623, which are specified cold rolled steel. The grades are classified according to the maximum permissible yield strength.

1008 carbon steel coil is primarily used in extruded, cold headed, cold upset, and cold pressed parts and forms. 1008 in the cold rolled condition is used for exposed or unexposed parts where bending, moderate drawing, forming and welding may be involved.

AISI 1018 carbon steel is a free machining grade that is the most commonly available grade around the world. Although its mechanical properties are not very, it still can be easily formed, machined, welded and fabricated.

1045 cold rolled steel coil is a medium carbon structural steel with good hot and cold workability and good mechanical properties. It is widely used in the industrial machinery manufacturing industry.
