The thickness of cold-rolled steel sheets is generally relatively small, and the thickness of hot-rolled plates can be larger. The surface quality, appearance, and dimensional accuracy of cold-rolled steel sheets are better than those of hot-rolled plates, and the thickness of cold-rolled steel sheets can be rolled as thin as about 0.18mm. a573 steel grade 58 carbon steel iron plate, Hot-rolled plates has high strength, good toughness, easy processing and good weldability and other excellent properties.

S355J2 steel plate a573 steel grade 58 carbon steel iron plate rolling process is controlled rolling process. In the rolling process, the ingot rolling temperature is 1000-1050℃; in the first stage, the low-speed and large reduction rolling process is adopted, the high-temperature stage is 950-1000℃, the rolling speed is 1.6-2.0m/s, the a573 steel grade 58 carbon steel iron plate single reduction rate is 15-20%, and the cumulative reduction rate is 40-45%, so as to ensure sufficient deformation of ingot. In the first stage, the start rolling temperature is 910-930℃, and the finish rolling temperature is ≤ 870℃.

In 2013, one of our clients in Korea purchased 890 tons Q345B square tube from us for one building construction project. Our clients required no burr in the side of the tube, we finally produce the goods with great condition and +/-0.25mm tolerance for wall thickness, which is a very great tolerance with customers’ required size. Our square tube full available range is 2-16mm for wall thickness, and 40-500mm for width. In addition, our Q/C department will seriously control all of the process of every order.
