Rectangular Tube

Carbon steel rectangular tubes are rectangular section pipes formed by hot rolling, cold bending or welding with carbon structural steel as raw material. Common materials include Q235B, Q355B, etc. They feature excellent bending and torsion resistance, stable structure, strong bearing capacity and high cost performance, making them widely used in steel structures and construction projects.
The product has regular section, high dimensional accuracy, firm welding and uniform wall thickness with reliable mechanical properties. It can be adapted to cutting, drilling, welding, bending, painting and other processing techniques. Compared with round tubes, rectangular tubes have larger contact surfaces, stable installation and are convenient for splicing and frame construction, while possessing good pressure resistance and deformation resistance.
Carbon steel rectangular tubes are widely used in building steel structures, factory columns and beams, curtain wall keels, shelf supports, guardrails and handrails, engineering machinery, vehicle manufacturing, prefabricated houses, advertising frames and various supporting structures. With the advantages of economy, reliability and convenient construction, they have become highly economical pipes widely used in industrial and civil construction.
