The square tube, as the name implies, is a square tube shape, which is rolled by strip steel after processing. Many kinds of materials can be formed into a square tube. What is the medium used for, and where it is used. Most square tubes are made of steel pipes. They are unpacked, flattened, crimped, and welded to form a round tube. Rolled into a square tube and then cut to the required length. Generally, there are 50 square tubes per package. In terms of stock, the large specifications are mostly 10*10*0.8-1.5~~500*500*10-25. The square tubes are divided into structural square tubes, decorative square tubes, and construction square tubes according to their uses. , Mechanical square tube, etc.
The square tube is a hollow square cross-section light thin-walled steel tube, also known as steel refrigerated bending section. It is a section steel with a square cross-sectional shape and size made of Q235 hot-rolled or cold-rolled strip or coil as the base material, which is formed by cold bending and then high-frequency welding. Except for the increased wall thickness, the corner size and edge flatness of the hot-rolled extra-thick-walled square tube reach or exceed the level of the resistance welded cold-formed square tube. Good comprehensive mechanical properties, good weldability, cold and hot workability and corrosion resistance, and good low temperature toughness.
The square tube is used in construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power generation brackets, steel structure engineering, power engineering, power plants, agricultural and chemical machinery, glass curtain walls, automobile chassis, airports, boiler construction, highway railings, Housing construction, pressure vessels, petroleum storage tanks, bridges, power station equipment, lifting and transportation machinery and other higher-load welded structural parts, etc.
