Manufactured by Hunan Yige Special Steel Science Technology Co.,Ltd since 2015, our heavy-duty welded square steel pipes deliver unmatched structural integrity for demanding conveyor systems. Operating from a 5,000-10,000㎡ ISO-certified facility in Changsha, we engineer these pipes to withstand extreme operational stresses while ensuring dimensional precision for seamless integration.
Key technical advantages include:
- Superior Load Distribution: 90° corners enhance weight-bearing capacity by 25% compared to round pipes
- Precision Welding: Automated ERW process ensures consistent weld penetration depth ≥1.2x wall thickness
- Corrosion Resistance: Optional hot-dip galvanizing (140g/㎡ coating) for harsh environments
- Custom Fabrication: Laser-cutting compatibility for bolt holes/slots (±0.2mm accuracy)
| Size (mm) | Wall Thickness | Max Load (kg/m) |
|---|---|---|
| 20×20 | 1.5-3.0mm | 320 |
| 50×50 | 2.0-6.0mm | 1,850 |
| 100×100 | 4.0-12.7mm | 7,200 |
Applications extend beyond conveyor frames to include:
- Pallet racking systems
- Automated warehouse structures
- Mining equipment supports
- Agricultural machinery frameworks
Trusted by industrial clients across 6 continents including North America, Western Europe, and Southeast Asia, our pipes undergo rigorous quality control per ISO9004/14000 standards. With 85% of production capacity dedicated to export orders, we offer:
- Bulk shipment optimization (40HQ container loading diagrams provided)
- Mill test certificates compliant with EN 10204 3.1
- Custom packaging (plastic caps/waterproof wrapping)
