CE Certified Single Selective Racking Factories & Exporters

Single Selective Racking provides 100% immediate selectivity to every pallet position without honeycombing or needing to shift adjacent pallets. For facilities managing high SKU diversity (such as e-commerce fulfillment, consumer electronics, and FMCG wholesale), it maximizes picking speed while keeping equipment capital expenditures modest. It supports conventional counterbalance forklifts, narrow-aisle reach trucks, and articulated trucks, making it the most universally adaptable steel storage system in modern warehousing.

CE marking under European Standard EN 15512:2020 verifies that the manufacturer’s structural engineering, cold-formed section geometries, and moment-resisting connections comply with European Union construction product safety laws. It certifies that the physical steel yield strength, buckling safety factors, second-order sway calculations, and weld integrity were audited by an accredited European notified body. For commercial buyers and EPC contractors, this simplifies municipal permits, satisfies strict Civil Defense regulations, and prevents project rejection by industrial insurers.

The concrete slab must be evaluated for point-load bearing capacity and flatness (typically DIN 18202 or ASTM E1155 F-min numbers). For heavy industrial selective racks (2,000–4,000 kg per beam level with up to 10-meter uprights), the slab typically requires a minimum compressive strength of 25–30 MPa, with adequate reinforcement to resist footplate punch-through shear. Our engineering team calculates exact baseplate surface areas and chemical/expansion anchor embedment depths based on your soil and floor slab test reports.

Upright frame calculation is not a simple linear sum of pallet weights. It requires rigorous structural modeling that accounts for: (1) Unsupported column height between beam levels (buckling length); (2) Accidental eccentricities in pallet placement; (3) Rotational stiffness ($C_d$) of the beam-connector claw; (4) Baseplate semi-rigidity on the concrete slab; and (5) Operational fork truck impact allowances (EN 15635 minimum 2.5 kN horizontal impact allowance). This ensures frames remain structurally sound throughout seismic and handling stresses.

All steel structural members undergo a computerized 10-step surface finishing sequence. Components enter an automated pre-treatment bath featuring hot alkaline degreasing, chemical acid pickling, rinsing, and zinc phosphating. This establishes an inert micro-crystalline zinc-phosphate conversion layer. Electrostatic epoxy-polyester hybrid powder is then applied and baked at 190°C–200°C. For open outdoor yards, chemical storage, or walk-in freezers down to -30°C, we provide hot-dip galvanized (HDG) finishes according to ISO 1461 standards.

To receive an engineered proposal within 24–48 hours, share: (1) Facility CAD drawings showing internal building dimensions, roof truss clear heights, building columns, and door/dock locations; (2) Pallet specifications (width, depth, maximum load height, and gross weight); (3) Operating forklift model, turning radius, and maximum reach height; (4) Total SKU profile and expected inventory throughput; and (5) Regional site factors (seismic zone classification or local Civil Defense fire-aisle regulations).

We use proprietary container-loading plans developed in 3D CAD to maximize ocean freight volume while safeguarding finished surfaces. Upright frames are bundled with protective corrugated paper interleafing, heavy corner protectors, and steel-strapped structural timber dunnage. Beams are palletized in matched-length bundles with connector claws guarded against impact. Every crate and bundle features weather-resistant labels corresponding with step-by-step CAD installation drawings, simplifying on-site sorting upon container arrival.

Yes. Our layouts are engineered to align with NFPA 13, EN 12845, and regional Civil Defense fire safety codes. We design single and double-row racking with 75mm to 150mm longitudinal and transverse flue spaces, allowing vertical heat rise to trigger ceiling smoke detectors and ceiling ESFR (Early Suppression Fast Response) sprinklers. Additionally, we provide galvanized wire mesh decking with open areas exceeding 70% to ensure uninhibited water penetration to lower pallet levels.
