Advantages of Carbon Steel Square Tubes ?

1. Uniformity

It provides regularity in size, shape, and tolerances, making it a popular choice for original equipment manufacturer (OEM) applications ;

2. Strength

square tubings have high tensile strength and are therefore extremely resistant to extreme temperatures and pressures ;

3. Low cost

Compared to other types of mechanical pipes, square pipes require less process. Therefore, it can reduce the cost of low budget items ;

4. Resistance

It is fire resistant and does not twist, split or shrink ;

5. Create Metal Structure

You can easily bend, punch or drill a square tubing to bind it to itself or any other material. These characteristics of square pipes make it very easy to build metal structures .


What is difference between Seamless steel pipe and Welded steel pipe?

Seamless steel pipe is manufactured by the round steel billet, through hot rolling, cold rolling or cold drawn processes, no seam on the pipe body. Welded steel pipe is manufactured by flat steel plate, with welding seam on the pipe body.
