CE Certified Industrial Warehouse Racking Systems Supplier & Exporters

Under European Standard EN 15512:2020, safe working loads (SWL) cannot be determined simply through crude manual deadweight tests. The standard requires finite element analysis (FEA) combined with empirical stub-column tests, beam end-connector bending tests, and frame sway shear tests. The certified maximum beam deflection must never exceed 1/200th of the clear beam span (L/200) under full design load with an ultimate limit state partial safety factor γF = 1.4 for dead loads and γQ = 1.5 for pallet variable loads. Guangzhou Heda Shelves validates every custom configuration through these parameters to guarantee absolute workplace safety against catastrophic frame collapse.

To size upright baseplates and calculate chemical anchor bolt embedment depths properly, our structural engineers require: (1) Concrete slab thickness (typically 150mm to 250mm reinforced concrete), (2) Concrete compressive strength rating (e.g., C20/25, C25/30, or 3000–4000 PSI), (3) Subgrade soil modulus of subgrade reaction (k-value), and (4) Floor flatness tolerance according to DIN 18202 or ASTM E1155 (FF/FL numbers). If floor flatness is outside normal tolerances, our engineers incorporate leveling shims (1mm to 5mm galvanized steel plates) to guarantee upright plumbness within 1/500th of vertical height.

During maritime transit lasting 30 to 50 days across tropical oceans, temperatures inside shipping containers can fluctuate between 10°C and 60°C, causing heavy condensation ("container rain"). Heda combats this with a three-pillar protection method: First, our steel undergoes automated 8-stage pre-treatment with chemical pickling and micro-crystalline zirconium phosphating to passivate the metal substrate. Second, we apply heavy thermosetting epoxy-polyester powder coating (80-120 μm dry film thickness) cured at 200°C. Third, bundled uprights and beams are wrapped with vapor-corrosion-inhibitor (VCI) film and desiccants before being strapped to wooden skids, preventing moisture infiltration.

The decision centers around SKU selectivity versus volumetric density. Selective Pallet Racking provides 100% immediate access to every pallet position, requiring standard aisles of 3.0m to 3.5m, yielding an average cubic utilization of 45%. Radio Shuttle Racking utilizes deep storage lanes (up to 40 pallets deep) where self-propelled battery carriers transport pallets inside channels, reducing aisle space by up to 75% and achieving up to 85% volumetric utilization. Radio Shuttle involves higher initial CapEx for shuttles and high-precision rails, but drastically cuts forklift travel times, eliminates rack collision damage, and delivers rapid payback in cold-storage and high-turnover beverage facilities.

Heda manufactures heavy-duty upright frames using continuous cold-formed Omega profiles available in widths of 80mm, 90mm, 100mm, 120mm, and 140mm, with wall thicknesses ranging from 1.8mm, 2.0mm, 2.3mm, up to 2.5mm and 3.0mm depending on height and payload. Frame horizontal and diagonal bracing members utilize heavy C-channel sections (typically 1.5mm gauge) bolted with grade 8.8 high-tensile lock nuts. Box beams utilize twin C-channels welded into a rigid interlocked rectangular section, ranging from 80×50mm up to 160×50mm, with connector claws stamped from 3.5mm to 4.0mm high-strength steel plate.

Yes. Guangzhou Heda Shelves specializes in both OEM and ODM custom fabrication. Our tooling tooling library supports popular worldwide hole pitch patterns, including European 50mm pitch metric teardrop/butterfly profiles, 75mm pitch profiles (compatible with standard Dexion / Stow configurations), and American 2-inch pitch teardrop punched patterns (RMI standards). We can custom-punch upright columns and match beam connector claw configurations so our frames and beams integrate seamlessly into your existing facility expansions without requiring complete system replacement.
