Product Description
Steel Space Frame Solutions for Large-Span Industrial and Commercial Buildings
With a 50,000-square-meter production base and a 50,000-ton yearly steel structure output capacity, Luoyang Innovation Building Material Co., LTD specializes in designing and producing high-performance Steel Space Frame systems. For airports, stadiums, industrial warehouses, and commercial complexes, our Space Frame solutions combine lightweight H-beams or square steel tubes with galvanized purlins to provide column-free spans up to 150 meters. Our end-to-end services, which include engineering design, precision manufacture, packing, and installation drawings, can expedite your project delivery by 30% to 50% when compared to traditional construction methods. We are certified to ISO9001, CE, COC, and PVOC standards.
Understanding the Space Frame System
A three-dimensional truss design called a Frame uses interconnected struts placed in geometric patterns to distribute loads. This structural method transfers forces in various directions using bolt-ball or welded-ball joints, in contrast to conventional two-dimensional trusses.
Internal columns are eliminated over enormous transparent spans in this design. For large pieces, the modular design lowers the cost of transportation. Compared to linear structural solutions, enhanced geometric stiffness offers better resilience to localized impact loads and seismic activity.
Where Steel Space Frame Structures Excel
Public Facilities and Transportation Hubs
Large, column-free interiors improve passenger flow and operational efficiency at airport terminals and high-speed rail stations. These frames are used in sports stadiums to provide thousands of spectators with unhindered sightlines.
Industrial Safety and Storage
The corrosion-resistant qualities of galvanized components are used in coal sheds, hazardous material warehouses, and limestone storage domes. Large footprints of bulk materials are shielded from environmental exposure by the stable roof system.
Commercial hubs and architectural landmarks
Double-curved surfaces and intricate organic shapes are achieved in shopping malls and exhibition facilities. In areas with significant snow accumulation and high seismic zones, the structure retains its performance integrity.

Why Choose Our Space Frame Solutions
Rapid Construction and Cost Efficiency
Factory prefabrication ensures 100% component accuracy before site delivery. Dry assembly methods eliminate curing time, reducing construction cycles by 30%-50%. Lightweight design cuts foundation costs by lowering ground treatment requirements.
Superior Structural Performance
Three-dimensional load distribution allows smaller member cross-sections while maintaining strength. Steel structures weigh 30%-40% less than reinforced concrete equivalents. Uniform material properties deliver exceptional earthquake and wind resistance.
Environmental Responsibility
Dry construction minimizes on-site dust, noise, and waste. Steel components are 100% recyclable, meeting ESG standards and circular economy principles. Our processes align with green building certifications for sustainable development.
Space Optimization and Flexibility
Thinner walls and smaller columns increase usable floor area by 3%-8%. Open layouts accommodate future renovations and production line reconfigurations without structural modifications.
Quality Assurance Through Rigorous Testing
Material Verification
Every batch undergoes hardness and tensile testing to confirm yield strength compliance. Full material traceability documentation tracks components from mill certificates through final installation.
Nodal Precision Inspection
Ultrasonic Testing (UT) and Magnetic Particle Testing (MT) detect internal fissures in welded ball joints. Digital measurement systems verify ball-hole angles and member lengths meet geometric accuracy standards.
Coating Durability
Salt spray testing simulates 1500-hour exposure cycles. Dry Film Thickness (DFT) measurements ensure galvanization layers meet C5-M protection levels for coastal and industrial environments.
Compliance Verification
All Steel Space Frame adhere to GB 50017, JGJ 7, and AISC 360 standards. Third-party inspections confirm structural stability under extreme wind loads and thermal expansion variables.
Installation Methodology and Support
Our engineering team provides detailed installation drawings for bolt-together assembly. Small-unit assembly methods eliminate the need for heavy cranes on constrained sites. Hydraulic jacking systems enable ground-level construction followed by lifting into final position.
Professional technical support guides you through design review, cost budgeting, and bidding preparation. We coordinate with local contractors to ensure precise execution during the assembly phase.
Frequently Asked Questions
Q: What span lengths can you achieve without internal supports?
A: Standard applications reach 120-150 meters using finite element analysis optimization. Custom designs extend beyond these limits based on load requirements and geometric configurations.
Q: How do you protect structures in coastal corrosion zones?
A: We apply C5-M coating systems combining hot-dip galvanizing with epoxy zinc-rich primers. These layers pass 1500-hour salt spray tests to guarantee decades of protection.
Q: Can installation proceed without large crane access?
A: Yes. Our small-unit assembly approach allows ground-level fabrication followed by hydraulic lifting. This method suits urban sites with height restrictions or limited crane access.
Q: What fire protection measures apply to steel members?
A: Intumescent fireproof coatings expand when heated to insulate structural steel. We specify R60 to R120 fire ratings based on local building codes and occupancy requirements.
Q: How much maintenance do these structures require?
A: Annual visual inspections check bolt tightness and coating condition at nodal points. Preventive monitoring of high-stress connections prevents localized oxidation and extends service life.
