Rectangular tube definition: Rectangular tube (RHS tube) is a rectangular hollow cross-section lightweight thin-walled steel tube, that is, a steel tube with unequal side lengths. Its structure is simple, stable, and has strong load-bearing capacity. The specifications of square tubes are usually expressed by side length and wall thickness.
Rectangular tubes are divided into seamless rectangular tubes and welded rectangular tubes. Seamless rectangular tubes are made of seamless round tubes through perforation and extrusion. Welded rectangular tubes are made of strip steel through process processing. Usually, the strip steel is made into round tubes through processes such as uncoiling, flattening, curling, and welding. Then the round tube is rolled into a rectangular tube and cut into the required length.
Features of rectangular tube:
1. Structural advantages: strong bending resistance in the long side direction (large moment of inertia), suitable for unidirectional force structures (such as beams, guide rails).
2. Lightweight: hollow design reduces weight by 30%-50% compared to solid steel, reducing transportation and installation costs.
3. Convenient connection: large flat contact area, easy to weld, bolt or assemble fixtures.
4. Diverse surface treatment: galvanized, spray-painted, polished, to meet different environmental requirements.
