Example: Our curved steel box girder bridge project in Southeast Asia .

Pre-fabrication: 70% of components are manufactured offsite in our Qingdao factory, reducing onsite labor by 50%.
​Logistics partnerships: Dedicated shipping lines with ​SPMT trailers​ for oversized cargo and ​carbon-neutral options.
​Real-time tracking: IoT sensors monitor cargo conditions during transit.
Delivery record: Completed a 500-ton stadium frame project in ​6 months, including design, fabrication, and installation.

Yes. Our engineering team offers:
​Code adaptation: Compliance with local seismic (GB 50011-2010) and wind (GB 50009-2012) standards.
​Material substitutions: Local steel grades (e.g., Q355B for China) with equivalent strength.
​Smart adjustments: Bolted connections for easy reconfiguration in rentable spaces.
Case study: Customized ​earthquake-resistant roof trusses​ for a hospital project in Japan.

Maintenance guides: Multilingual manuals with weld inspection protocols and coating upkeep.
​On-site assistance: Engineers available for critical erection phases (additional cost).
Example: Provided training for a Middle Eastern client’s assembly team to reduce onsite errors.

​Flexible payment: 30% deposit via TT, 70% LC or escrow for large orders.
​Currency options: USD, EUR, CNY, and regional currencies (e.g., AED, JPY).
​Risk mitigation: FOB/CIF pricing models to simplify logistics planning.
