Brief Introduction Of Rectangular Tube


Rectangular tube is a new type of steel structure material, which is widely used in bridges, ships, buildings, oil pipelines, and other engineering fields. It is composed of flat steel and cross arranged according to certain relative angles.
Rectangular tube can be divided into electric welded rectangular tube and seamless rectangular tube according to the production method, and it is about 8%-10% lighter than traditional square tube per meter. Generally speaking, electric welded rectangular steel pipe is divided into high-frequency welding tube, submerged arc welding tube, and resistance welding tube according to the welding method.

The common types of rectangular tubes are 20mmx30mm-500mmx400mm, 10mmx20mm-200mmx300mm, 1mmx2mm-20mmx30mm, and the wall thickness is 0.5mm-20mm. The materials commonly used for the rectangular tubes are Q195-Q345, 10#-20#, and all sizes of non-standard specifications can be customized according to customer requirements.
The production process of the rectangular tubes is complex, involving the steel strip production process, tube blank production process, welding process, and finishing process. It has good rigidity, uniform thickness of the wall, good coefficient of thermal expansion, corrosion resistance, and other properties, and it can effectively save raw materials and reduce production costs.
Rectangular tube is widely used in bridge, construction, automobile, shipbuilding, machinery manufacturing, container, transportation, and other fields. In addition, the rectangular tube can be processed into various shapes of round, rectangular, and elliptical tubes, thus meeting the special requirements of production.
Rectangular tube has high strength, lightweight, strong bearing capacity, and strong corrosion resistance, and their use has wider local application prospects. Therefore, it is highly favored by customers, and its application value can be realized.
