Products Description
GB/T700 Q235C hot rolled plates are produced in accordance with ASTM A283 in the United States. Q represents the yield of Q235C material, and the latter 235 refers to the yield value of Q235C material, which is about 235MP.
The yield value will decrease with the increase of Q235C steel plates thickness. Due to its moderate carbon content and better comprehensive properties, the properties of Q235C hot rolled plates such as strength, plasticity and welding have been well matched and Q235C steel are widely used.

Products Application
Q235C steel are often rolled into medium and thick GB/T700 Q235C hot rolled plates. Q235C hot rolled plates are widely used in architectural and engineering structures, to build building frame, high voltage transmission tower, bridge, vehicle, boiler, vessel, ships and so on. Q235C steel are also used as a mechanical part with less high performance requirements.
