Square Tubes are hollow-section square steel materials that fall under the category of steel pipes. They can be classified into welded square tubes and hot-rolled seamless square tubes based on the manufacturing process. Square tubes are characterized by excellent cross-sectional performance, lightweight, and strong bending and torsional resistance, making them widely used in construction, machinery manufacturing, and decorative applications.

 

Production Processes

• Welded Square Tubes: Formed by coiling cold-rolled or hot-rolled steel strips and high-frequency welding.
• Seamless Square Tubes: Made from round pipe blanks through hot rolling, perforating, and cold drawing processes.
• Surface Treatments: Options include hot-dip galvanizing, cold galvanizing, painting, and polishing.

 

Product Features and Advantages

 

1. Superior Structural Performance:

 

Square cross-section provides isotropic properties, ensuring balanced resistance to bending and torsion.

 

2. Lightweight with High Strength:

 

The hollow structure reduces weight while maintaining strength.

 

3. Good Processability:

 

Easy to cut, weld, and drill for secondary processing.

 

4. Diverse Connection Methods:

 

Can be connected through welding, bolting, or clipping.

 

5. Aesthetic Appeal:

 

Simple lines make them suitable for modern architectural styles.

 

6. Economic and Practical:

 

High cost-performance ratio with low overall usage costs.
