Classification of square tubes
What are the categories of square tubes? Is the price list of square tubes different for different production processes?
1. According to the production process, the square tube is divided into: hot-rolled seamless square tube, cold-drawn seamless square tube, and extruded seamless square tube. The welded square tube is divided into:
(a) According to the process - arc welded square tube, resistance welded square tube (high frequency, low frequency), gas welded square tube, furnace welded square tube
(b) According to the welding seam - straight seam welded square pipe, spiral welded square pipe,
The square tube is divided into seamless and welded, and the seamless square tube is formed by extruding a seamless round tube.
2. The square tube is divided into: ordinary carbon steel square tube, low alloy square tube. Common carbon steel is divided into: Q195, Q215, Q235, SS400, 20 steel, 45# steel, etc.; low alloy steel is divided into Q345, 16Mn, Q390, ST52-3, etc.
Different square tube price lists are different, because different production processes correspond to different manufacturing standards, and the price lists are also different for different standards. Contact our experts for real-time pricing.

The main purpose of the square tube
From the above introduction, we can see that the price of square tube is low. The square tube has very reliable stability, so what are the specific uses?
The uses of square tubes include construction, machinery manufacturing, steel construction and other projects, shipbuilding, solar power 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, oil storage tanks, bridges, power station equipment, lifting and transportation machinery and other welded structural parts with higher loads, etc.
Square tube is a hollow square section light thin-walled steel pipe, also known as steel cold bending section. It is 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. In addition to the thickening of the wall thickness of the hot-rolled extra-thick-walled square tube, its corner size and edge straightness have reached or even exceeded the level of the resistance-welded cold-formed square tube. It has good comprehensive mechanical properties, good weldability, cold and hot working properties and corrosion resistance, and has good low temperature toughness.
No matter how the price list of the square tube changes, only the value will be reflected in practical application. Whether you buy steel for your own use, or you are a steel distributor, doing steel business, then you want to get real-time prices, please contact our experts.
