Galvanized Square Tube Weight Calculation:

To calculate the weight of a galvanized square tube, multiply the theoretical weight by the zinc coating factor of 1.06 (e.g., 50×50×4mm galvanized square tube: 5.74kg/m × 1.06 ≈ 6.08kg/m).

Customized Services:

Tianjin Yuantai Derun offers customizable non-standard specifications, with wall thicknesses ranging from 0.5mm to 25mm and lengths from 4 to 24 meters. Flexible supply options are available to meet specific project needs.
