| Specifications（mm×mm） | Wall Thickness (mm) | Theoretical Weight (kg/m) | Remarks |
| 20×20 | 1.2 | 0.75 | Conventional small-size square tubes suitable for lightweight structures |
| 40×40 | 2.0 | 2.29 | Common specifications suitable for building frames |
| 40×40 | 4.0 | 4.68 | Thick-wall design enhances load-bearing capacity |
50×50 | 2.5 | 3.81 | Common specifications for curtain wall projects |
50×50 | 3.0 | 4.44 | Balancing strength and cost |
50×50 | 4.0 | 5.74 | Applicable to high-demand scenarios |
50×50 | 7.75 | 11.67 | The technology breaks through the specifications and is specially designed for curtain wall aluminum profile inserts. The wall thickness far exceeds the industry norm. |
60×60 | 3.0 | 5.38 | Suitable for medium load-bearing structures |
80×80 | 4.0 | 9.96 | Common specifications for large building frames |
80×80 | 6.0 | 13.85 | Suitable for heavy structures such as bridge supports |
100×100 | 4.0 | 11.65 | Large structures such as industrial plants and stadiums |
100×100 | 8.0 | 23.00 | Ultra-thick wall design, extreme load-bearing requirements |
300×500 | 9.75 | Specific calculation required | Extra-long specification, up to 26.5 meters, for use in automated logistics warehouses. |
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.
Technical Breakthroughs:
50×50×7.75mm Square Tube: Breaking the industry standard of 5.75mm wall thickness, this design is specifically designed for curtain wall aluminum profile inserts, achieving ultra-thick wall thickness, high dimensional precision, and excellent mechanical properties.
300×500×9.75×26.5m Square Tube: Set a record for the industry's longest length, this tube is used in automated logistics warehouses to ensure stability and safety. Application Scenarios Covered:
From lightweight building frames to heavy industrial structures, from curtain wall projects to new energy applications (such as photovoltaic mounting systems), Tianjin Yuantai Derun square tubes meet diverse needs with a full range of specifications and high performance.
