PRODUCT DESCRIPTION
Seamless Rectangular Steel Tube is a cost-effective carbon steel construction material with a hollow rectangular cross-section. It offers the same bending and torsion strength as solid round steel but with less weight.
Our seamless rectangular steel tube is ideal for a variety of applications including construction, machinery manufacturing, shipbuilding, solar power generation, steel structure engineering, power plants, agricultural machinery, automobile chassis, and more.

1. High Strength: Seamless rectangular steel tubes have uniform wall thickness and no weld seams, making them less prone to cracking. They have higher strength compared to welded rectangular steel tubes, allowing them to withstand greater pressure and tension, making them more versatile.
2. High Precision: The production process of seamless rectangular steel tubes is more precise, resulting in high dimensional accuracy and regular geometric shapes. This makes them ideal for applications requiring precise dimensions, such as high-precision machinery, instruments, and the automotive industry.
3. Strong Corrosion Resistance: The smooth inner and outer surfaces of seamless rectangular steel tubes, along with no weld seams, prevent the accumulation of corrosive substances and impurities, providing excellent corrosion resistance. They are widely used in industries such as chemical, petroleum, and aerospace for transporting corrosive media.
4. Uniform Stress Distribution: During the production and forming process of seamless rectangular steel tubes, the material's grain structure is denser, resulting in a more uniform internal stress distribution. This reduces the likelihood of weld-induced heat affected zones and deformation, enhancing overall strength.
5. Easy Installation: Seamless rectangular steel tubes are easy to install and do not require welding, making them suitable for complex and confined environments. Additionally, they can be cold bent and shaped as needed, reducing issues related to heat treatment and heat affected zones.

PRODUCT PERFORMANCE
Seamless rectangular steel pipe is made of seamless pipe as base material, through double drawing or cold drawing, also known as round to square. The main processing flow of seamless rectangular steel pipe is: round steel → pipe blank → inspection → heating → perforation → sizing → hot rolling → flat head → inspection → pickling → spheroidizing annealing → cold drawing → forming → flat end → inspection.
