square steel tubing is a kind of square pipe, which is a steel pipe with equal sides. It is a strip of steel that has been processed and rolled. Generally, the strip is unpacked, flattened, crimped, welded to form a round tube, and then rolled into a square tube by a round tube and then cut into a desired length.
Square tube introduction：As the name implies, the square tube is a square tube type. A variety of materials can form a square tube. It is used in the medium, and what is used. Most square tubes are made of steel pipes. Flat, curled, welded to form a round tube, which is then rolled into a square tube and then cut to the required length. Generally, 50 pieces of each of the sacred square tubes are mostly in the size of the spot in the 10*10*0.8-1.5~~500*500*10-25, and the square tube is used for the structural square tube, the decorative square tube, and the building square tube. , mechanical square tube, etc.
Square tube product features and uses：
1. square tube product description
The square tube is a hollow square section light thin-walled steel pipe, also known as steel refrigeration curved profile. It is a section steel of square cross-section shape made by Q235 hot-rolled or cold-rolled strip or coiled steel as the base material after cold bending forming and then high-frequency welding. In addition to thickening of the wall thickness of the hot-rolled thick-walled square pipe, the corner size and the straightness of the edge are both at or above the level of the cold-formed square tube of the resistance welding.
2. square tube use
The use of square tubes includes construction, machinery manufacturing, steel construction projects, shipbuilding, solar power brackets, steel structure engineering, power engineering, power plants, agriculture and chemical machinery, glass curtain walls, automotive chassis, airports, boiler construction, highway railings, houses. Building, etc.
