Custom OEM Warehouse Racking Mezzanine Factories & Wholesalers

A structural mezzanine utilizes wide-flange structural steel columns (H-beams) and continuous primary/secondary joists, providing large clear spans (up to 12m) underneath for forklifts, sorting conveyors, or office space. A rack-supported mezzanine uses cold-rolled pallet rack uprights and shelf frames as the supporting load columns, maximizing multi-tier picking bin density at lower material cost but with fixed aisle spacing beneath.

Yes. Every export project for the USA and Canada is calculated according to the American Institute of Steel Construction (AISC 360), Rack Manufacturers Institute (RMI MH16.1), and International Building Code (IBC) provisions. Our engineering department provides complete design calculation packages and coordinates directly with your project's local Professional Engineer (PE / SE) of Record for city permit approvals.

We supply three primary industrial flooring options: (1) Galvanized or painted open steel bar grating, which allows natural light and sprinkler water penetration; (2) Heavy-gauge ribbed steel B-deck overlaid with high-density tongue-and-groove tongue-ply wood or ResinDek panels for smooth pallet jack and robot traffic; and (3) Heavy-duty checkered anti-slip steel plate for harsh industrial environments.

Standard live load deflection criteria for general storage mezzanines are calculated at L/240 or L/300 of the span length under maximum Uniformly Distributed Load (UDL). For platforms accommodating delicate robotic automation, AGVs, or sensitive office mezzanine partitions, we engineer structural joists to more rigid L/480 or L/600 tolerances to eliminate perceptible dynamic bounce.

Under NFPA 13 regulations, mezzanines exceeding specific floor area thresholds require designated under-deck fire sprinkler arrays. Open bar grating with over 50% open area often allows overhead ESFR sprinklers to penetrate multiple levels without supplementary under-deck piping, subject to review by local municipal fire marshals.

Depending on total structural dead weight and live load ratings (e.g., 500kg/m² vs 1,500kg/m²), mezzanine column point loads typically range from 50 kN to over 250 kN. We engineer customized oversized baseplates (e.g., 300x300mm up to 600x600mm, 20-30mm thick) to evenly distribute bearing pressure across standard 6-inch to 8-inch reinforced concrete slabs (3,000–4,000 PSI) without requiring individual footing excavations.

Standard fabrication cycle times range between 4 to 6 weeks from final signed approval of structural shop drawings. Thanks to our 35,000 m² automated facility and robotic roll-forming lines with capacity exceeding 100,000 metric tons per annum, multi-container enterprise orders (10 to 50+ 40HQ containers) are produced in scheduled rolling batches to meet tight construction schedules.

For interior ambient warehouses, our automated electrostatic epoxy powder-coating provides durable abrasion resistance (60–80 microns). For corrosive environments, outdoor covered platforms, or refrigerated storage (-24°C), we offer hot-dip galvanization conforming to ISO 1461 / ASTM A123, providing complete zinc metallurgical immersion that prevents rust for decades.

Yes. We act as a contract OEM/ODM production facility for leading storage wholesalers, system integrators, and engineering firms across North America, Europe, and Australasia. We provide custom profile roll-tooling, proprietary connector punching, private label branding, and custom color matching according to client-specified RAL color codes.

Upright frames, structural H-beams, and joists are bundled using protective heavy-gauge wooden dunnage, high-tensile steel strapping, and waterproof poly-wrapping. Delicate connection plates, hardware, bolts, and baseplates are crated in seaworthy, fumigated wooden cases to guarantee rust-free and zero-deformation arrival at the project jobsite.
