Top Trusted Industrial Shelving System Supplier & Suppliers

All steel components undergo an industrial 10-stage chemical pretreatment line prior to coating. This process includes hot alkaline degreasing, industrial acid pickling to eliminate mill scale, and zinc phosphating to establish an impermeable crystalline conversion layer. Components are then coated with an exterior-grade electrostatic thermoset polyester powder baked at 180°C. For open yard storage or high-salinity marine environments (e.g., Jebel Ali, Jeddah, Dammam), we supply hot-dip galvanized steel finishes complying with ISO 1461, ensuring over 25 years of corrosion-free mechanical integrity.

To prepare an approval-ready proposal, our civil and mechanical engineering team requires: (1) Architectural CAD floor plan highlighting column grids, building expansions joints, and clear height under roof joists; (2) Unitized pallet parameters: width, depth, overall height (including pallet structure), and gross weight; (3) Forklift performance specifications: mast collapse height, maximum lift elevation, turn radius, and outrigger dimensions; (4) Desired throughput dynamics: number of unique SKUs, seasonal surge peaks, and target pallet turnover per shift.

Yes. Our layouts are explicitly drafted to satisfy local Civil Defense, OSHA, and NFPA fire prevention codes. We engineer longitudinal and transverse flue spaces (typically 150mm to 300mm) within back-to-back rack arrays to ensure rapid vertical heat venting and unobstructed water penetration from ceiling ESFR (Early Suppression, Fast Response) fire sprinklers. For deep-lane storage systems exceeding 6 meters, our engineering schematics incorporate dedicated pipe-bracket mounting channels for integrated in-rack sprinkler lines.

Every production batch leaves our Guangzhou factory accompanied by traceable Quality Inspection Certificates. We maintain active CE Certification (No. 2435-CPR-8605159) for structural steel fabrication under EN 1090 standards, alongside ISO 9001:2015 Quality Management accreditation (No. 18624Q00169R0M). Raw coils are purchased directly from certified primary steelmakers (e.g., Baosteel, Shougang) with 3.1 Material Test Reports (MTR) verifying yield strength (fy ≥ 235 N/mm²), elongation, and chemical composition.

Export freight preservation is a core element of our quality management system. Upright frames are nested with high-density corrugated spacers and wrapped in waterproof polyethylene stretch film to prevent salt-air penetration. Horizontal beams are bundled in uniform lots with protective steel edge-guards, banded using heavy-duty tensile polyester straps, and positioned on custom timber dun-nage skids. Every bundle features color-coded, waterproof QR barcodes mapped directly to the project installation assembly drawings, accelerating sorting at the jobsite.

We provide a hybrid engineering support structure. For standard selective or longspan configurations, we supply comprehensive, step-by-step 3D assembly shop drawings, bolt torque specifications, and high-definition video walkthroughs supported by real-time video conferencing with our bilingual field engineers. For complex multi-tier mezzanine floors, radio shuttle automation, or automated vertical lift modules (VLM), we deploy factory-certified field installation supervisors directly to your site to oversee local labor, perform laser column leveling, and conduct final dynamic load testing.
