OEM/ODM Single Deep Selective Pallet Rack Exporter & Exporters

Single Deep Selective Pallet Racking provides 100% immediate accessibility to every single stored pallet position, requiring only standard counterbalance or reach forklifts. Double Deep Racking stores pallets two rows deep, which increases floor storage density by approximately 25-30% by eliminating aisles, but drops direct selectivity to 50% and requires specialized pantograph deep-reach forklifts. Single deep racking is the global standard for facilities handling diverse SKUs with rapid inventory turnover, cold rooms requiring strict FIFO batch control, and distribution hubs serving ecommerce operations.

For industrial pallet racking installations with upright heights exceeding 6 meters and bay loads exceeding 10,000 kg, the concrete slab should typically be reinforced with a minimum compressive strength of C25/30 or 3,000 to 4,000 PSI. The slab thickness should generally be at least 150 mm to 200 mm, crack-free, and engineered to support both the concentrated footplate point loads and dynamic forklift wheel stresses without excessive differential settlement. We recommend a floor flatness rating matching DIN 18202 or ASTM E1155 (FF/FL numbers) to prevent forklift mast oscillation at elevated lift heights.

Under both ANSI MH16.1 and European EN 15512 codes, the maximum allowable vertical deflection for an industrial rack load beam under uniform distributed load (UDL) is Span / 200 (e.g., a 2,700 mm beam has a maximum permissible sag of 13.5 mm under rated full payload). Our engineering team designs box beams with custom wall thicknesses (1.5mm to 2.0mm) and internal vertical stiffeners, factoring in a structural safety factor of 1.5 to 1.65 to ensure the steel remains strictly within elastic limits under normal operation.

For ambient inland distribution centers, our automated electrostatic thermosetting epoxy-polyester powder coating (60-90 microns thick) provides long-lasting abrasion and chemical resistance. However, for continuous cold stores (-25°C to -30°C) with cyclic condensation, or coastal warehouses exposed to saline air, we recommend hot-dip galvanization (HDG compliant with ISO 1461) or zinc-rich primer pre-treatment. HDG bonds a 70-100 micron metallurgical zinc layer that self-heals minor scratch damage and stops rust migration on internal column surfaces.

To provide an accurate CAD floor plan, 3D model, and structural load quotation, please provide:

1. Warehouse architectural drawings showing clear ceiling height, building column centers, floor joints, and overhead fire sprinkler/lighting clearances.
2. Pallet dimensions (Width × Depth × Height including goods) and maximum gross weight per pallet.
3. Forklift make, model, maximum mast lift height, and minimum turning radius (Right Angle Stacking Aisle AST).
4. Target inventory handling method: FIFO (First In, First Out) or LIFO (Last In, First Out).
5. Local seismic acceleration zone coefficients or wind load requirements (for outdoor racking).

Upright frames are exported in heavy-duty knock-down (KD) condition: columns, horizontal braces, diagonal braces, baseplates, and row spacers are bundled separately using high-tensile steel banding, corrugated corner protectors, and moisture-barrier film. Beams are stacked in custom wooden-sleeper bundles nested by size. This knockdown approach packs roughly 18 to 22 metric tons of structural racking into a standard 40-foot High Cube (40'HQ) container, cutting ocean freight costs per pallet location compared to pre-assembled welded frames.

Every shipment includes an engineered installation package containing: 2D assembly layout drawings with numbered bay sequences, torque tightening specifications for expansion anchors, and 3D exploded connection views. We offer remote video support with our bilingual structural engineers. For enterprise logistics projects above 5,000 pallet positions, we can dispatch on-site bilingual installation supervisors to train and oversee local mechanical crews.
