Square tube definition: Square tube (SHS tube) is a square hollow cross-section lightweight thin-walled steel tube, that is, a steel tube with equal side lengths. Its structure is simple and stable, and it has high load-bearing capacity. The specifications of square tubes are usually expressed in terms of side length and wall thickness.
Square tubes are divided into seamless and welded seams. Seamless square tubes are made by perforating and extruding seamless round tubes. Welded square tubes are rolled from strip steel through process treatment. Generally, the strip steel is unpacked, flattened, curled, and welded to form a round tube. The round tube is then rolled into a square tube and then cut to the required length.
Classification of square tube:
Square tubes are divided according to the production process: hot-rolled seamless square tubes, cold-drawn seamless square tubes, extruded seamless square tubes, and welded square tubes.
By material: carbon steel square tube, stainless steel square tube, alloy steel square tube, etc.
By use: structural square tube, decorative square tube, building square tube, etc.
By surface treatment: galvanized square tube, painted square tube, black tube (no coating).
Features of square tube:
1. Light structure but high strength: hollow design reduces weight while maintaining bending and torsion resistance.
2. Easy to process: can be cut, welded, drilled, and adapted to a variety of installation needs.
3. Corrosion resistance: galvanized or stainless steel square tubes are suitable for humid or corrosive environments.
4. Aesthetics: The appearance is neat and suitable for exposed occasions (such as decoration, railings).
