With ISO 9001, CE, and GB certifications, our steel systems comply with global aviation safety standards, while our 120,000-ton annual production capacity ensures bulk order fulfillment within 60-90 days, offering factory-direct pricing that reduces project costs by 15-20%.
Product Advantages
High-strength Core Engineered for Airport Industrial Resilience
- Unmatched Load-bearing Capacity: Constructed with Q355/Q460 high-strength steel, achieving an average steel consumption of 115kg/㎡—a benchmark far exceeding conventional light steel workshops. The structural backbone features welded cross-shaped steel columns, delivering exceptional bidirectional mechanical performance, significantly enhanced vertical load-bearing capacity, and robust horizontal lateral resistance.
- Seismic & Wind Resistance Excellence: Designed to withstand seismic intensity of 8 degrees and category 12 typhoons, perfectly adapted to Qingdao's coastal climate challenges. Certified by globally recognized authorities including CE, ISO, and SGS, the structure boasts a 50-year design lifespan, providing long-term safety assurance for precision manufacturing, bonded logistics, and aviation supply chain operations.
72m Column-free Span Revolutionizing Industrial Space Efficiency
- Three-dimensional Space Optimization: The flagship building features an unprecedented 72m clear span without intermediate columns, combined with a three-story, 20m-tall vertical layout. This transformative design eliminates traditional single-story workshop limitations, enabling flexible zoning of multi-tier production lines, precision assembly bays, and climate-controlled storage areas.
- Precision Manufacturing Assurance: Employing full-penetration ultra-long weld technology, every structural connection undergoes rigorous quality control through ultrasonic testing and radiographic inspection. This ensures minimal structural deformation, exceptional dimensional stability, and micron-level precision—critical for supporting aerospace component production, semiconductor manufacturing, and other high-precision industrial processes.

SAfter comparing with three suppliers, we chose Yidongxiang. Their quotations were transparent and were 8% lower than those of their competitors. They also provided complete material inspection reports and CE certifications. What made us most satisfied was their modular design. Now, if we want to expand the warehouse, we only need to add a few modules, and the cost is much lower than rebuilding from scratch.
-
JYidongxiang's construction speed is truly remarkable. Our 10,000-square-meter warehouse was completed and delivered within just 45 days after the contract was signed. Moreover, their overall service is very professional. From design to installation, there are dedicated personnel handling each step. We hardly had to worry about any details.

DWe need warehouses with snow-resistant structures in our logistics park in Toronto. The design team of Yidongxiang optimized the roof load according to the local climate and adopted thickened H-shaped steel and a snow accumulation drainage system. Last year, during the rare heavy snowfall, the warehouse suffered no damage at all and the quality exceeded expectations completely.
