1. Characteristics and usage of square tubes
(1). The simple description of square tube products
The square tube is a kind of light thin-walled steel pipe with a hollow square section. It is also called steel cold-formed profiles. It is a section steel with square cross-section shapes and sizes, which is made of Q235 hot-rolled or cold-rolled strips or coils as the base material after cold bending and high-frequency welding. In addition to the wall thickness thickening, the corner size and edge flatness of hot-rolled extra thick wall square pipes reach or even exceed the level of resistance welding cold formed square pipes. It has good comprehensive mechanical properties, weldability, cold and hot working properties and corrosion resistance. It has good low temperature toughness.
(2). The usage of square tubes
The square tube is widely used in many projects like machinery manufacturing, steel construction, shipbuilding, solar power stents, 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, oil tanks, bridge and power station equipment.
2. Quotation of square tubes
The price of square tubes is generally around 8,000 tons. However, this is just the price for only reference. It is changeable and different at different stages. Many kinds of materials can be used to form square tubes. What is its medium for? Where is it used? Most square pipes are made of steel pipes. After unpacking, flattening, crimping and welding, the round steel tubes are rolled into square tubes and then cut into the ones with the required length. In general, the specification of the most if 50 square pipes per bag in stock is 10*10*0.8-1.5-500*500*10-25 mm. The square tubes can be divided into structural square pipes, decorative square pipes, construction square pipes, mechanical square pipes, etc according to the application.
3. The identification methods of square tubes
With the development of our economy, there are more and more fake products in society. In order to prevent people from being cheated when buying square tubes, we need to know some knowledge about how to judge the authenticity of square tubes: "we can judge by observing the surface smoothness and flatness of square tubes. If the surface of square tubes is relatively flat, it can reflect that the square tubes are good. However, if the surface is not so flat, and the size and thickness are not standardized, it can reflect that the square tube is of poor quality.
