Steel Roof Structure for Industrial Lights Warehouse
Our warehouses utilize a Gable Frame (Rigid Frame) System, which is the global standard for industrial buildings. By focusing on structural symmetry and high-tensile steel members, we provide a stable, reliable, and highly efficient building envelope.
Integrated Rigid Frame: All primary columns and rafters are fabricated from high-grade structural steel, designed to transfer loads efficiently to the foundation.
Precision Secondary Framing: Our C and Z-section purlins and girts are galvanized or painted for long-term corrosion resistance, providing a secure secondary framework for cladding.
Seismic & Wind Optimization: Every design is custom-calculated to meet local building codes, ensuring the structure can withstand extreme wind velocities and seismic tremors without compromising integrity.

Product Advantages
Expansive Column-Free Interiors: Our rigid frame designs allow for massive clear spans (up to 60m+). This provides an unobstructed floor plan for high-density racking, automated conveyor systems, and large-scale machinery movement.
Rapid Modular Assembly: Every component is factory-prefabricated to millimeter-level tolerances. On-site installation is primarily a bolt-only process, slashing construction timelines by up to 50% compared to traditional masonry.
Superior Durability: Utilizing high-yield structural steel (Q355B/Q235B), our warehouses offer a high strength-to-weight ratio, ensuring the building remains stable under heavy snow loads or high-vibration industrial use.
Low Maintenance & Life-Cycle Value: Steel is resistant to pests, fire, and rot. When combined with our premium coating systems, maintenance costs are virtually eliminated over the building's lifespan.
Manufacturing & Quality Excellence
CNC Fabrication Technology: We utilize multi-axis CNC drilling, high-definition plasma cutting, and automated plate shearing to ensure that every structural joint fits perfectly on the first attempt.
Submerged Arc Welding (SAW): All primary frames undergo automated SAW processing, resulting in deep-penetration, defect-free welds that surpass manual welding standards.
Non-Destructive Testing (NDT): 100% of critical welds undergo Ultrasonic (UT) or Magnetic Particle (MT) testing to verify subsurface integrity.
Trial Assembly Protocol: For complex structural nodes, we conduct a factory trial assembly to eliminate the risk of on-site misalignment during international installation.
Global Logistics & Installation Support
Optimized Containerization: Our logistics team uses 3D loading software to secure components into 40HQ or Open Top containers, maximizing space and protecting steel members from transit damage.
Intuitive Labeling & Documentation: Every steel member is etched with a unique ID that corresponds to our detailed 3D shop drawings, making the erection process as simple as possible for your local crew.
Technical Advisory: We provide 24/7 remote technical support via video link. For large-scale infrastructure projects, we can mobilize on-site supervisors to lead the installation and quality check process.
Frequently Asked Questions
You are manufacture factory or trading company?
