Transportation Hub Steel Structures – Engineered for Connectivity
Nantong Sudong Steel Structure Co., Ltd. is a professional Transportation Hub manufacturer and supplier based in China, with nearly three decades of experience in heavy steel structures. We design, fabricate, and install steel frameworks for airports, viaducts, railway stations, and other transport infrastructure. Our factory in Nantong spans 50,000 m² and houses seven production lines, including six intelligent robotic welding lines, achieving an annual capacity of 40,000–50,000 tons. We serve global clients with ISO 9001, EN1090 CE, and GOST certifications, ensuring compliance with international standards.
Our transportation hub solutions are built for durability, precision, and speed of construction. From the Pudong Airport Steel Structure to the SCG Zhejiang Taizhou Viaduct, we have proven capability in complex, large-scale projects. We offer a one-stop service from conceptual design to installation support, making us a reliable partner for public infrastructure projects worldwide.
Our Transportation Hub Range
We supply a comprehensive range of steel structures tailored to transport applications. Each product type is engineered to meet specific load, span, and environmental requirements.
| Product Type | Typical Applications | Key Features |
|---|---|---|
| Airport Terminals | Passenger terminals, concourses, hangars | Long-span roof structures, large clear spans, seismic resistance |
| Viaducts & Bridges | Highway overpasses, railway viaducts | Box girder fabrication, high load capacity, corrosion protection |
| Railway Stations | Station canopies, platforms, concourses | Modular design, quick installation, aesthetic finishes |
| Bus & Transit Hubs | Bus terminals, transit centers | Lightweight structures, integrated canopies, cost-effective |
Engineering and Design Support
Our in-house engineering team uses TEKLA modeling for detailed design and clash detection. We review customer drawings, optimize connections, and generate precise material lists. This ensures that every component is fabricated accurately and fits perfectly on site.
- 3D modeling and collision detection
- Connection design and detailing
- Material selection and optimization
- Shop drawing preparation and approval
Materials and Specifications
We use high-strength structural steel grades (e.g., Q235, Q355, S355) with certified mill test certificates. For transportation hubs, we prioritize corrosion resistance and fire protection. Our surface treatment follows ISO 12944, with shot blasting and multi-layer painting systems. We also offer galvanized or specialized coatings for aggressive environments.
Critical specifications we address include span length, column spacing, load combinations (dead, live, wind, seismic), and deflection limits. We work with your structural engineer to ensure compliance with local codes and standards.
Manufacturing and Quality Control
Our factory is equipped with advanced machinery: laser/plasma cutting (±0.5mm accuracy), CNC drilling (±0.3mm hole accuracy), and robotic welding stations. We perform 100% inspection on critical welds using non-destructive testing (NDT). Each component is traceable via a unique ID, ensuring full quality control from raw material to final assembly.
We hold ISO 9001, EN1090 CE, and GOST certifications, and our quality system is audited regularly. For international projects, we can arrange third-party inspections (e.g., SGS, BV) upon request.
Installation and On-Site Support
We provide detailed installation manuals and videos. For complex projects, we can dispatch experienced engineers to supervise erection. Our team coordinates with your contractors to ensure smooth assembly, including bolt-up and welding procedures. We also offer remote technical support 24/7.
Logistics and Delivery
Located in the Yangtze River Delta, we are 1.5 hours from Shanghai Port, Nantong Port, and Zhangjiagang Port. We offer container shipping (20GP/40GP/40HQ, open-top, flat-rack) and bulk cargo for oversized components. For Russia and Central Asia, we use the China-Europe Railway Express. Our packaging protects components during transit, with fumigated wooden boxes for precision parts.
Information We Use to Configure Your Solution
To prepare a precise proposal, we need the following project data:
- Architectural and structural drawings (PDF or CAD)
- Site conditions (wind, seismic, snow loads)
- Required design codes and standards
- Project timeline and delivery schedule
- Special requirements (e.g., fire rating, acoustic performance)
Send these to our sales team, and we will respond with a preliminary solution within 12 hours.
FAQs
What certifications do your transportation hub structures hold?
Our products are manufactured under ISO 9001, EN1090 CE, and GOST certifications. We can provide certificates and test reports upon request.
Can you handle large-span structures like airport roofs?
Yes, we have experience with long-span structures, including the Pudong Airport project. Our box girder production lines and heavy lifting capacity (80-ton cranes) enable us to fabricate large components.
Do you provide installation supervision?
Yes, we offer optional on-site installation guidance by our engineers. We also provide detailed manuals and videos for self-installation.
What is your typical lead time?
Lead time depends on project complexity and quantity. For standard components, it is typically 4-6 weeks after drawing approval. We will confirm a schedule in our quotation.
Can you customize the steel structure to our design?
Absolutely. We work from your drawings or concept, providing detailed engineering and fabrication. Our TEKLA modeling ensures accuracy and constructability.
