China Wholesale Wide Span Shelving Factories & Suppliers

While selective pallet racking is engineered primarily for full-pallet storage handling via counterbalanced or reach forklifts (with beam capacities exceeding 1,000–4,000 kg per level), Wide Span Shelving (also called Longspan) is explicitly optimized for non-palletized manual picking, bulky items, cartons, and bin storage. Wide span uses lighter cold-formed uprights (e.g., 55 × 47mm vs. 90 × 70mm for pallet rack) and step beams configured with internal recessed lips for steel shelves, wire decking, or timber panels. Loading capacities range from 300 kg to 1,000 kg per beam level, providing a substantially more cost-effective investment per cubic meter for hand-loaded inventory.

Safe load calculation requires evaluating Uniformly Distributed Loads (UDL) against the section modulus and moment of inertia of the beam profile under FEM 10.2.02 standards. The standard deflection limit is L/200, meaning that across a 2,000mm span, total vertical deflection under maximum design load must not exceed 10mm. Furthermore, safety factors of 1.5 to 1.65 are applied against the yield strength of the steel (Q235B yield strength ≥ 235 MPa). Our engineering department supplies complete finite element structural calculations and stamped load capacity plaques with every project.

We offer three primary decking types based on application and fire safety regulations:
1. Solid Steel Panels: Zinc-passivated or powder-coated cold-rolled steel. Ideal for heavy small-part bins, preventing loose stock from falling through, and wipe-down cleanliness.
2. Welded Wire Mesh Decking: Formed steel wire with under-deck support channels. Recommended for NFPA sprinkler compliance, enabling overhead water penetration and maximum air/light circulation.
3. High-Density Chipboard / MDF: Economical for dry retail store-rooms and e-commerce picking; typically supplied in 18mm to 25mm thickness with galvanized drop-in retaining clips.

Components are completely knock-down (KD) engineered. Uprights can be shipped assembled or flat-packed as individual posts and bracing channels to save shipping volume. Beams are nested head-to-tail in bundles of 50 to 100 units, banded with PET straps, and cushioned with corrugated buffer wrap and heavy plastic film. Steel panels are stacked on wooden pallets with perimeter corner protectors. A standard 40HQ container typically accommodates 22 to 26 metric tons of racking, representing upwards of 1,200–1,800 linear meters of shelving depending on frame dimensions.

Yes. Our uprights are punched with continuous automated 50mm or 75mm hole pitches engineered to accommodate both shelf-support step beams and structural mezzanine floor purlins. By extending upright columns up to 6,000mm–8,000mm in height, we can construct 2, 3, or 4-tier rack-supported mezzanine walkways with integrated steel stairs, landing decks, safety handrails, and pallet pivot kick-gates, doubling or tripling your usable floor area without costly civil warehouse expansion.

As an experienced direct exporter, HEDA Shelves delivers a complete international documentation package: Bill of Lading (B/L), Commercial Invoice, Detailed Packing List with itemized container weights/volumes, Certificate of Origin (Form E for ASEAN, Form A/CO for global ports), CE Declaration of Performance (DoP), ISO 9001:2015 mill test reports, and non-wood packing declarations or fumigation certificates where solid timber pallets are utilized. Racking is classified under HS Code 7308.90.

Standard lead times for full container load (FCL) orders typically range from 15 to 22 working days following technical drawing confirmation and deposit settlement. Custom powder coat colors (RAL specific), heavy-gauge galvanizing, or specialized OEM tooling stamps may add 5–7 days. For urgent expansion projects, standard 2,000mm × 600mm × 2,000mm wide span starter and adder bays are maintained in semi-finished inventory for accelerated 10-day dispatch.

Every shipment includes a detailed installation manual with 3D exploded assembly diagrams, part identification tags matching the packing list, and clear fastener torque specifications. For complex multi-tier mezzanine or high-bay racking systems, we provide remote video installation guidance, CAD component coordinates, and—upon request—can dispatch experienced factory project managers to oversee local assembly crews on-site.
