China Steel Structure Construction Company — Turnkey Project Services
Most steel structure suppliers in China stop at fabrication. We take full responsibility: from the first structural calculation to the 20-year maintenance inspection. One contract, one point of accountability.
One Partner, Four Phases, Zero Finger-Pointing
The typical steel structure project involves a designer, a fabricator, an erector and a maintenance contractor. When something goes wrong, each blames the other. Our full-cycle model eliminates that risk: we own all four phases.
Design & Engineering
Structural analysis, BIM modeling, code-compliant design and feasibility studies. Our engineers review your drawings within 24 hours.
Fabrication & Manufacturing
200,000-ton annual capacity. Self-developed CAD-CAM intelligent production lines. Ten core manufacturing technologies, from ultra-long-span trusses to thick-plate narrow-gap welding.
Construction & Erection
Certified erectors, fully equipped machinery. We master jacking, lifting, sliding and tensioning technologies for complex spatial structures.
Maintenance & Operation
Structural inspections, anti-corrosion recoating, bolt torque verification and structural health monitoring. We remain accountable long after handover.
Design & Engineering: Where Turnkey Projects Begin
Send us your architectural concept, your loading requirements, or even a sketch on a napkin. Our structural engineers translate it into a fabrication-ready, code-compliant design.
What Our Design Team Delivers
- Structural design compliant with Chinese (GB), European (Eurocode) and American (AISC) standards
- 3D BIM modeling with clash detection before any steel is cut
- Feasibility analysis including span optimization, load path verification and material quantity estimation
- Connection design for bolted-sphere grids, welded truss joints, and thick-plate column splices
- Foundation interface drawings that coordinate steel anchor bolts with concrete contractor
- Drawing review within 24 hours of submission, with written engineering feedback
Why This Matters for Your Project
Most Chinese steel structure contractors fabricate to your drawings without questioning them. If a connection detail is suboptimal, they build it anyway and charge you for the extra steel.
Our design team has 50+ R&D engineers, over 60% holding senior professional titles. In 2023, we established the Research Center for Intelligent Construction of Spatial Steel Structures jointly with Shanghai Jiao Tong University. We hold a Class-A Special Design Qualification for light steel structures, one of only a handful of companies in China with this license.
This means we can optimize your design for material efficiency, constructability and long-term performance, not just build what we are told.
Fabrication: 200,000 Tons of Intelligent Manufacturing
Our 100,000m² production workshops produce 200,000 tons of grid structures, trusses and steel structures annually. But tonnage is not the point. Precision is.
Ten Core Manufacturing Technologies
- Ultra-long-span steel truss fabrication
- H-shaped truss with complex joints fabrication
- Curved box truss fabrication
- Steel pipe and profile top-bending fabrication
- Partially encased steel-concrete composite (PEC) structure fabrication
- Cross-shaped to box-shaped steel column fabrication
- Double-curved beam and spiral staircase fabrication
- Thick-plate narrow-gap welding
- Ultra-low temperature service structural steel welding
- Digital pre-assembly technology for steel structures
Each technology addresses a specific fabrication challenge that determines whether your structure can be built at all, not just whether it can be built cheaply.
CAD-CAM: Design Data to CNC, Zero Manual Interpretation
The biggest source of fabrication error is human interpretation: a draftsman draws a dimension, a foreman reads it differently, and a welder builds to his own understanding. Our self-developed intelligent production line eliminates this gap.
Design data flows directly from our engineering software into CNC cutting, drilling and welding equipment. The production management system monitors every operation in real time. This is not a marketing claim; it is the foundation of our digital transformation strategy.
For clients, this means: what we design is exactly what we build. Tolerances are tighter. Rework is minimal. Inspection reports match drawings without "as-built" fudges.
Construction: Beyond Bolting Steel Together
Erecting a steel structure is not just crane work. For spatial grid structures, long-span trusses and high-rise frames, the method of assembly determines whether the structure performs as designed.
Four Construction Technologies We Master
- Jacking — raising entire roof systems hydraulically, simultaneously, with millimeter precision. Used for grid roofs over operating facilities where crane access is impossible.
- Lifting — hoisting pre-assembled truss segments weighing hundreds of tons into final position with synchronized cable systems.
- Sliding — pushing bridge and roof structures along temporary rails into final position without closing the space below.
- Tensioning — applying prestress to cable-strut and beam-string structures to achieve design deflection and load distribution.
3,000,000m² Annual Construction, Certified Crews
Our annual construction capacity exceeds 3,000,000m². Every specialized worker is certified and fully equipped with machinery. We undertake pipe trusses, grid structures, steel frames and metal roofing with equal competence.
Our particular strength is in spatial structures: we hold multiple construction method patents for jacking, lifting and sliding erection. We built the world's longest-span prestressed beam-string coal shed at 229m. We erected the steel structure for China's first new-era Antarctic research station. These are not standard projects; they require construction methods that most contractors have never attempted.
Why a Turnkey Steel Structure Project in China Saves You More Than Money
A turnkey project means one contract, one accountable party, one warranty. Here is what that eliminates from your project risk profile.
No Interface Disputes
When the designer, fabricator and erector are different companies, every interface becomes a risk. Tolerances do not match. Welding specs conflict. Schedule delays cascade. As a turnkey steel structure contractor in China, we eliminate these interfaces entirely.
Faster Project Delivery
Design optimization starts while fabrication is being scheduled. Construction planning begins while steel is being cut. Phases overlap because one team owns the schedule. Typical time saving: 20-30% versus multi-contractor models.
Controlled Cost, No Surprises
One contract means one price. Design changes are resolved internally, not through change orders between companies. Material optimization by our design team typically saves 5-15% on steel weight before fabrication begins.
Single Warranty, Full Accountability
If a weld cracks, a bolt loosens or a coating fails, there is no debate about whose fault it is. We designed it, we built it and we erected it. We fix it. Our maintenance team remains on call throughout the structure's service life.
