Product Advantages
  • Maximizing Storage Density: Our high-tensile steel frames allow for massive clear spans and high eave heights, enabling the use of high-density racking systems and optimizing every cubic meter of your facility.
  • Rapid Operational Readiness: Every warehouse component is precision-manufactured in our factory. This systematic approach allows for a "bolt-together" assembly on-site, shortening the transition from ground-breaking to inventory loading by up to 50%.
  • Superior Floor Loading Support: We engineer our structures to integrate seamlessly with heavy-duty industrial flooring, ensuring the building can support the constant movement of high-capacity forklifts and heavy pallet loads.
  • Industrial-Grade Resilience: Built to defy the elements, our warehouses are custom-calibrated to resist extreme wind loads, seismic tremors, and heavy snow, providing a safe and stable environment for high-value assets.
  • Economic Scalability: The modular nature of our steel warehouses allows for effortless longitudinal expansion. As your storage needs grow, your facility can be extended with minimal disruption to ongoing operations.
Premium Materials & Manufacturing Excellence
  • High-Strength Framework: We exclusively utilize certified Q355B and Q235B structural steel, providing the perfect balance of ductility and load-bearing capacity for large-scale storage spans.
  • CNC Precision Fabrication: Our facility employs multi-axis CNC drilling and high-speed laser cutting to ensure that every structural node and bolt hole is perfectly aligned, eliminating the need for on-site modifications.
  • Heavy-Duty Protective Finishes: To combat the humid or corrosive environments common in logistics hubs, we offer multi-tier coatings including high-micron hot-dip galvanization and industrial-grade epoxy primers.
  • Specialized Cladding Systems: We offer a variety of high-performance envelope options, including fire-rated Rockwool sandwich panels and high-R-value PU cores to maintain stable internal temperatures for sensitive inventory.
  • Automated Fusion Welding: Utilizing submerged arc welding (SAW) technology, we ensure that every primary beam and column joint has a deep-penetration weld for maximum structural integrity.

Quality Control & Certifications
  • International Safety Compliance: Our production processes are fully certified to ISO 9001:2015 and CE standards, ensuring our warehouses meet the most stringent international building codes.
  • Non-Destructive Integrity Checks: We implement rigorous Ultrasonic Testing (UT) and Magnetic Particle Inspection (MPI) on all critical welds to ensure the building is free from subsurface flaws.
  • Complete Material Traceability: Every project is delivered with a comprehensive quality dossier, including Mill Test Certificates (MTCs), providing full transparency for your insurance and engineering audits.
  • Factory Trial Assembly: For complex structural geometries, we perform pre-shipment trial fittings to verify that every component fits precisely, guaranteeing a smooth installation process overseas.
  • Third-Party Validation: We facilitate independent inspections by global leaders such as SGS, BV, and TUV, ensuring the final warehouse structure adheres to your specific quality benchmarks.

Global Logistics & Installation Support
  • Logistical Efficiency: Our experts utilize 3D nesting software to maximize container volume, reducing your shipping costs and ensuring that all warehouse components are securely braced for long-distance transit.
  • Comprehensive Erection Toolkit: Every shipment includes a detailed "Warehouse Assembly Pack," featuring serialized 3D blueprints, instructional videos, and a granular inventory map for your installation team.
  • Intuitive Component Mapping: Every steel member is etched with a unique ID tag. This "plug-and-play" identification system allows for rapid sorting and placement on-site, even by crews with minimal specialized training.
  • 24/7 Technical Consultations: We provide real-time video-link support to assist your site supervisors, ensuring that any technical queries during the erection phase are resolved instantly by our engineers.
  • Global Field Supervision: For massive logistics parks, we can mobilize experienced technical advisors to your site to oversee quality control and provide leadership throughout the construction cycle.
