Top Trusted Storage Racking Shelves Manufacturers & Exporters

Our structural engineering team produces calculation books based on the American Rack Manufacturers Institute (RMI ANSI MH16.1), EN 15512, and FEM standards. By evaluating your facility's seismic acceleration coefficients (Ss, S1), soil site class, and clear building height, we calibrate upright section dimensions, horizontal/diagonal bracing geometry, and anchorage bolt embedment depths to ensure full approval by local building authorities.

For standard selective pallet racks with 1,000–2,000 kg per level, a concrete slab compressive strength of 3,000 to 4,000 PSI with a minimum thickness of 150mm–200mm (6"–8") is generally adequate. For multi-tier drive-in or 4,000 kg extreme beam systems, our engineers calculate concentrated point loads per post and provide custom widened baseplates to safely distribute soil bearing pressure.

All structural parts are bundled with high-tensile steel strapping, corner protectors, and heavy air-cushioned poly-wrapping. Uprights and beams are staggered using computer-modeled 3D container stuffing schematics to maximize weight and cube inside 40ft High Cube containers while eliminating transit abrasion and bending deformation during multi-week ocean crossings.

Yes. We routinely fabricate 96", 108", and 144" clear span box and step beams with standard 42" and 48" frame depths specifically tailored for standard 48" x 40" Grocery Manufacturers Association (GMA) pallets. Load capacity documentation and engineering layouts are furnished in both imperial (lbs, ft, in) and metric systems upon request.

To satisfy NFPA 13 sprinkler regulations, our CAD layouts incorporate necessary longitudinal and transverse flue spaces (typically 3" to 6" open gaps). We provide heavy-duty galvanized wire mesh decking with open grid ratios exceeding 70% to facilitate unhindered water penetration from ceiling ESFR (Early Suppression, Fast Response) fire sprinkler heads to lower tiers.

Our standard manufacturing lead time is 15 to 25 business days from structural drawing approval, supported by our 30,000-ton monthly capacity. While we handle full-scale logistics projects with dozens of 40HQ containers, our minimum order quantity for standard warehouse racking starts at one 20ft container to ensure cost-effective freight rates.
