HEDAHeavy Duty Racking
English
Español
EnglishEspañolConfigured for intense operational duty cycles, heavy dynamic loadings, and strict international seismic standards. Each configuration undergoes comprehensive Finite Element Analysis (FEA) to verify structural integrity under peak warehouse throughput.
Operating directly adjacent to the prestigious Canton Fair Complex in Pazhou, Guangzhou, HEDA Shelves maintains an expansive heavy-duty roll-forming and automated coating base. By utilizing strictly certified Q235B cold-rolled structural steel, fully robotic gas-shielded welding, and automated continuous punching lines, we manufacture industrial racking architectures that surpass EN 15512, RMI MH16.1, and AS4084 structural verification guidelines.
Get CatalogManaging risk across long-distance ocean logistics, seismic design restrictions, and extreme warehouse floor space pressures demands certified structural design and accountable manufacturing tolerances.
We source prime Q235B coil coils from state mills. Uprights and boxed step beams undergo non-destructive tensile testing, guaranteeing yield strengths of ≥235 MPa with precise elongation ductility.
Our multi-station CNC profiling machines punch, slit, and roll upright profiles with continuous hole pitch accuracy within ±0.1mm, eliminating onsite assembly stress and misalignments.
Equipped with in-house parametric CAD/BIM software, our application engineers deliver preliminary layouts, dynamic capacity calculations, and container loading simulations within 8 hours.
Escalating land acquisition values, stringent cold-chain regulations, and the rapid rise of dark warehouses dictate that modern racking infrastructure must function as an integrated structural and computational sub-system.

Pure static storage is declining. Procurement budgets are shifting rapidly toward radio-shuttle carts, automatic guided vehicles (AGVs), and autonomous mobile robots (AMRs). Racking components now mandate micro-tolerance guide tracks, anti-bounce stops, and optical sensor reflector brackets.
Major insurance underwriters and municipal fire codes enforce strict adherence to L/200 and L/250 maximum beam deflection thresholds. In seismic regions (Ecuador, Chile, New Zealand, Japan), oversized footplates with dual anchor studs and diagonal back-to-back bracing are non-negotiable.
Warehouse operators prioritize life-cycle value over raw procurement costs. Electrostatic dry powder coating using high-performance polyester resins prevents premature flaking, pitting, and rusting, ensuring over 15 years of maintenance-free service even in humid tropical distribution centers.
Ocean freight volatility forces suppliers to rethink structural nesting. HEDA engineers components with precise taper angles, boltless bracket configurations, and modular bolted frames, maximizing standard 40ft High Cube container volumetric stuffing rates up to 26–28 metric tons.
Direct engineering clarifications addressing beam deflection ratios, sub-zero cold storage metallurgy, seismic safety ratings, and containerized logistics.
Selective Pallet Racking provides 100% immediate selectivity to every single pallet position, making it ideal for high-SKU velocity logistics hubs and FMCG centers. However, it requires an aisle for every two rack runs, yielding an average floor utilization rate of 40%–50%.
Double Deep Pallet Racking stores pallets two deep on back-to-back rows, reducing aisle requirements by 50% and increasing total cubic volumetric capacity by up to 60%. It requires specialized pantograph deep-reach forklifts and operates on a First-In, Last-Out (FILO) logic for each lane.
Our engineering team incorporates the dynamic response spectra outlined in RMI (Rack Manufacturers Institute) MH16.1, European standard EN 15512, and AS4084. In high-risk seismic zones, our designs implement widened footplates (thickness up to 10–12mm), dual Hilti wedge anchor anchorings, heavy-gauge diagonal column bracing, and reinforced beam end-connectors with 5-tooth hooks.
Every high-bay seismic system is verified via Finite Element Analysis (FEA) under fully loaded simulated seismic accelerations to prevent structural tipping or catastrophic joint shear failures.
Under continuous sub-zero temperatures, structural steel undergoes a ductile-to-brittle transition. To prevent micro-cracking and instantaneous brittle fracture under forklift impact:
1. Steel Grade Selection: We specify certified structural carbon steel with optimized carbon equivalents and phosphorus/sulfur levels tightly controlled below 0.035%.
2. Welding Metallurgy: Gas-shielded flux-cored automated welding utilizing low-hydrogen consumables to avoid cold-induced hydrogen-assisted cracking.
3. Pre-treatment: Multi-stage chemical bath degreasing and zinc-phosphate conversion coating before powder bake-off, preventing moisture penetration beneath the polymer film.
In accordance with international standards, the structural design criterion for maximum beam vertical deflection under Uniformly Distributed Load (UDL) is δ ≤ L / 200 (where L is the clear span distance between upright columns). For sensitive automated crane applications or high-density shuttle bays, we engineer to δ ≤ L / 250 or L / 300 to guarantee flawless clearance for automated guided mechanisms.
Yes. Overseas clients simply provide building dimensions, column grid spacing, floor slab slab load limits, ceiling truss heights, sprinkler pipe clear heights, and their pallet specs (Width × Depth × Height + Gross Weight).
Our engineering team generates a comprehensive 2D CAD layout, egress circulation flow diagrams, forklift turning radii calculations, and a high-resolution 3D BIM rendering within 8 business hours at zero initial cost.
Structural uprights are bundled with heavy-duty timber dunnage and high-tensile steel strapping. Step beams are palletized with protective corrugated cardboard dividers between each layer to eliminate coating abrasions. Small connection accessories, gravity safety pins, leveling shims, and expansion bolts are packed in double-walled wooden crates or reinforced export cartons.
All bundle profiles are precision-calculated to maximize internal container dimensions, preventing transit movement and maximizing cargo tonnage without bulging.
