The hot steel strip from the last rolling mill of finishing rolling is cooled and then coiled into steel coil by the coiler. Carbon Steel coils can be divided into general carbon structural steel and low-alloy steel according to their raw materials and functions. According to different uses, they can be divided into cold-formed steel coil, car structural steel coil, corrosion-resistant structural steel coil, mechanical structural steel coil, welded gas cylinders, and energy. Pressure vessel steel, pipeline steel, etc. According to the different needs of users, through different finishing lines (flattening, straightening, cross-cutting or slitting, inspection, weighing, packaging and marking, etc.) It is processed to flat rolled and slit steel strip products.
Commonly used steel plate materials: Q235B, Q345B/C/D/R/Q, SPHC, Q510L, etc.
Including high carbon steel coil, medium carbon steel coil and low carbon steel coil. This kind of steel contains less sulfur, phosphorus and non-metallic inclusions than carbon structural steel , Mechanical properties are relatively good, so it is widely used in shipbuilding, automobile beams, construction platforms, welding of large steel structures, pressure vessels and other manufacturing industries.
