Product Description

Square tube is a name for square tube. Aluminum square tube belongs to Al-Mg-Si alloy, with medium strength, good plasticity and excellent corrosion resistance. In particular, it has no tendency to stress corrosion cracking, and has excellent weldability, corrosion resistance and cold workability. It is an aluminum alloy product with wide application prospects.

Shaped tube

Special-shaped seamless steel pipe is a general term for seamless steel pipes with other cross-sectional shapes other than round pipes.

According to the shape and size of the steel pipe section, it can be divided into equal-wall thickness special-shaped seamless steel pipe, unequal wall thickness special-shaped seamless steel pipe, and variable-diameter special-shaped seamless steel pipe.

Shaped seamless steel pipes are widely used in various structural parts, tools and mechanical parts. Compared with the round tube, the special-shaped tube generally has a larger moment of inertia and section modulus, and has a larger bending and torsion resistance, which can greatly reduce the structural weight and save steel.

Special-shaped pipes are divided into: special-shaped square pipes, rectangular special-shaped pipes, special-shaped welded pipes, spiral welded pipes, etc.

Applications

Application of Aluminum Square Tubing：

The aluminum square tubing is an aluminum square tube that pulls the profile aluminum square tube out of the required radian through a bending machine. The arc of the greenscape building materials can reach a maximum of 100 degrees, and the direction of the arc can be either the same direction or the opposite direction. Aluminum square tube is suitable for bright and transparent, and is mostly used in shopping malls, subways, schools, exhibition halls, highway service areas, libraries and other places.
