Prefabricated Industrial Metal Steel Structure Frame Storage Hangar Construction Warehouse
Our warehouses leverage the Rigid Frame System, the international benchmark for industrial stability and cost-efficiency. By focusing on structural symmetry and high-tensile steel members, we deliver an exceptionally stable and reliable building envelope.
- Integrated Rigid Framework: Primary columns and rafters are fabricated from premium Q355B/Q235B structural steel, precision-engineered for optimal load distribution and foundation efficiency.
- Corrosion-Resistant Secondary Framing: All C and Z-section purlins and girts receive professional-grade galvanization, providing a secure, rust-proof framework for the building's cladding across diverse climatic conditions.
- Localized Code Compliance: Every design is custom-calibrated to meet specific regional building codes (such as ASTM, Eurocode, or GB), ensuring the structure defies localized wind velocities, seismic activity, and heavy snow accumulation.

Product Advantages
- Expansive Column-Free Interiors: Our rigid frame engineering facilitates massive unobstructed floor plans, creating flexible environments ideal for high-density racking, automated fulfillment systems, and large-scale machinery movement.
- Accelerated Speed-to-Revenue: Every component is factory-prefabricated to millimeter-level tolerances, with on-site installation as a streamlined "bolt-together" process that significantly reduces construction timelines.
- Superior Material Integrity: Utilizing high-yield structural steel, our warehouses offer superior strength-to-weight ratio, ensuring stability under extreme industrial stress and vibration.
- Extended Life-Cycle Value: Steel is naturally resistant to pests, fire, and rot, with industrial-grade epoxy or galvanized coating systems that virtually eliminate maintenance requirements over decades.
Premium Materials & Manufacturing Excellence
- CNC Digital Fabrication: Multi-axis CNC drilling and high-definition laser cutting ensure perfect structural joint alignment, eliminating the need for on-site modifications.
- Submerged Arc Welding (SAW): All primary frames undergo automated SAW processing, resulting in deep-penetration, defect-free welds that consistently outperform manual welding standards.
- Pre-Erection Trial Fit: Complex structural nodes are trial-assembled at our facility to validate geometry and bolt-hole alignment before reaching your project site.
Quality Control & Certifications
- International Certifications: ISO9001:2015 and CE certified, meeting rigorous safety and quality standards for global markets.
- Full-Process Monitoring: Strict QC protocols (IQC, IPQC, FQC) implemented from raw material sourcing to final product dispatch.
- Professional NDT Testing: Ultrasonic or Magnetic Particle Testing on critical welds ensures zero-defect structural joining.
- Pre-Assembly Inspection: Factory trial assemblies for complex joints guarantee 100% alignment during on-site installation.
- Third-Party Inspection: Long-term collaboration with SGS, BV, and TUV provides independent, traceable quality assurance reports.
Global Logistics & Installation Support
- Volumetric Shipping Optimization: Our logistics team uses 3D nesting software to maximize container volume, reducing shipping costs while protecting components from transit stress.
- Intuitive Component Marking: Every steel member is etched with permanent, unique tracking IDs corresponding to detailed 3D shop drawings for straightforward erection.
- Technical Advisory Services: We provide 24/7 remote technical support via video link, with on-site supervisors available for large-scale infrastructure projects.
Frequently Asked Questions
You are manufacture factory or trading company?
As a direct manufacturing facility based in Qingdao, China—just a stone's throw away from the Qingdao Port—we pride ourselves on our stringent quality management system, expert design team, robust production capabilities, and extensive manufacturing experience.
How about your quality control?
1) We only cooperate with high-quality raw material suppliers with strength and reputation, and our quality inspection department conducts 100% strict testing on raw materials before entering our factory.
2) Our workers are all certified and regularly assessed to guarantee production quality.
3) During production, we implement self-inspection, mutual inspection, and workshop inspection—only qualified products move to the next step.
4) Before delivery, inspection teams check everything against delivery lists to ensure complete item shipment for local installation.
What's the delivery time?
Usually 30 days. We have perfect management plans for each project to ensure on-time delivery.
Do you offer service for installation?
Yes, we provide detailed installation drawings and videos. Generally, you can install locally as components are prefabricated and bolted. Otherwise, we can send engineers to guide installation.
What's the payment term?
We offer two payment terms:
1) 30% advance payment before production by T/T, and 70% balance by T/T before shipping.
2) 100% irrevocable L/C
How to get a fast quotation?
Please send us your project preliminary drawing, and we will quote accordingly within 2 days. Alternatively, we can confirm requirements with you and provide a detailed quotation list promptly.
Is your price competitive compared with other companies?
As a direct factory, our prices are competitive with guaranteed quality and pricing.
