CE Certified Conventional Pallet Racking Manufacturer & Factories

EN 15512 is the European design code governing structural steel pallet racking, using limit state design principles with specific partial safety factors applied to steel materials, loads, and beam connector rotational stiffness. ANSI MH16.1 (RMI standard in North America) utilizes Allowable Stress Design (ASD) or Load and Resistance Factor Design (LRFD). CE-certified racks tested under EN 15512 undergo rigorous physical stub-column tests, beam-end connector moment tests, and frame shear tests to calculate actual buckling curves rather than theoretical estimates.

Pallet rack upright frames transfer heavy point loads to the concrete slab through footplates. For instance, a 5-tier frame storing 1,000kg per pallet can exert an axial load exceeding 10,000 kg (100 kN) on a single post. Prior to installation, we verify slab thickness (typically 150mm–250mm reinforced slab), concrete compressive strength (minimum C20/25 or 3,000 PSI), and sub-base compaction. Larger enlarged spreader baseplates (e.g., 180×140×8mm) are engineered when point stresses approach maximum punch-through limits.

Under EN 15620 and FEM 10.2.02, standard pallet rack horizontal beams are limited to a maximum vertical elastic deflection of δ = L/200 (where L is the clear span distance). For a standard 2700mm beam carrying two 1000kg pallets, maximum allowable central deflection is 13.5mm under fully loaded static conditions. For automated crane systems or high-level Narrow Aisle trucks, stricter tolerances of L/300 or L/400 are enforced to avoid snagging bottom pallets during automated lift and retraction.

Civil defense codes and NFPA 13 require proper flue spaces to permit early sprinkler activation and vertical heat dissipation. Back-to-back rack rows are designed with rigid row spacers providing a minimum longitudinal flue space of 75mm to 150mm. Transverse flue spaces (minimum 75mm between pallets) must be maintained at all beam bays. In high-pile configurations exceeding 7.6 meters, our engineering packages integrate bracket attachment points for intermediate in-rack sprinkler pipework directly onto the upright frame bracings.

Certified Q235B and Q355B carbon steels have verified manganese and carbon chemical bounds, delivering defined minimum yield points (235 MPa and 355 MPa, respectively) and elongation percentages (≥26%). Uncertified commercial commercial steels often contain inconsistent internal grain boundaries, leading to sudden brittle cracking during cold roll-forming or catastrophic failure under seismic impulse shock. We supply official Mill Test Certificates (MTC) with full chemical and tensile trace data for every production batch.

Forklift impact accounts for over 85% of structural racking damage. To prevent frame collapse, we manufacture heavy-gauge 5.0mm steel column protectors anchored directly into the floor (isolated from the rack upright), heavy-duty wrap-around polymer post guards, and continuous full-depth tubular end-of-aisle barriers. Aisle entry uprights can also be specified with reinforced double-front legs up to 1.2m height.
