There are many types of rectangular steel pipes for your project. The rectangular steel tube has excellent mechanical and structural properties, which make it popular for many industries, including:
1.Automotive and Aerospace Industry
Compared with round pipes, rectangular hollow pipes have larger moments of inertia and section modulus, greater bending and torsion resistance, better structure, and can reduce their own gravity and save steel. Therefore, square pipes are widely used in construction, power engineering, steel structure engineering, steel construction and other engineering construction projects. Besides, it is commonly seen in our life, such as handrails, bicycle frames, car rotating shaft, steel scaffolding, bridges, highways, greenhouses, etc.
As the price is mainly influenced by cost of production, such as different materials, grades, and finish. Hollow rectangular tube price extensively ranges from $450 to $900 per ton. We offer a fair price in global market. If you have interest in our product, we will send you a set of price list and offer you the best price!
1.Pay attention to the pipe surface.
There are no broken lines on a standard rectangular steel tube surface. Folding is a variety of fold lines formed on the surface of a rectangular tube, and this defect often runs through the longitudinal direction of the entire product. The folded product will crack after being bent, and the strength of the steel will be greatly reduced.
2.There are no pock and impurities on a high quality steel pipe surface.
The pitted surface is the irregularity of the surface of the steel due to the serious wear of the rolling groove. The inner diameter of inferior rectangular pipe fluctuates greatly, and such steel pipe is prone to fracture due to uneven stress.
3.The inner diameter of inferior rectangular hollow tube fluctuates greatly, and such steel pipe is prone to fracture due to uneven stress.
4.The cross ribs of inferior steel rectangular tubes are thin and low, and often appear dissatisfied.
5.The composition of the high-quality rectangular tube is uniform, the end face of the cut end is smooth and neat, while the surface of the low-quality steel is uneven and has no metallic luster.
