Calculations are theoretical (density 7,850 kg/m³). Kg/m tables vary by spec; we’ll confirm on your quote. Galvanizing available on request. Square = A=B. For tight tolerances, provide drawing/spec.
Structural tubing is a hollow steel section, typically square, rectangular, or circular in shape.
It is used in construction and engineering for frames, supports, and load-bearing structures because it provides high strength, stability, and resistance to bending and torsion.
