Product introduction
Hollow square steel pipe is a welded steel pipe with a square cross-section, commonly used in door and window frames, railings, and brackets.
Product advantages
High Strength
The square pipe is cold-formed from Q235B carbon structural steel and boasts a compressive load capacity exceeding 500 kg/m.
Strong Welds
The square pipe is resistance-welded, resulting in a tensile strength in the weld zone close to that of the parent material, reducing the risk of cracking.
High Straightness
After forming, the tubes undergo multiple straightening processes to ensure a straightness tolerance of ≤1.5mm/meter, minimizing assembly errors.
