Fabricated from certified high-tensile Q235B and Q355B cold-rolled structural steel, our storage systems deliver certified load capacities up to 5,000 kg per beam level with automated robotic roll-forming precision.
Guangzhou HEDA Shelves Co., Ltd. (established in 2001) operates one of Asia’s most sophisticated cold-rolled steel forming facilities, providing end-to-end custom OEM/ODM racking manufacturing with direct port export dispatch.
We operate 16 high-precision continuous roll-forming lines capable of handling steel thickness from 1.5mm to 3.5mm with micro-tolerances under ±0.2mm across 12-meter continuous upright columns.
Every structural upright, beam, and bracer undergoes rigorous chemical pre-treatment: degreasing, multi-stage acid pickling, zinc-phosphating, and curing in electrostatic thermoset polyester powder tunnels.
Engineered structural calculations and factory inspections comply with demanding international procurement specifications, verified by third-party testing institutions.
The shift toward omnichannel distribution, automated mobile robotics (AMRs), cold-chain expansion, and high-cube cubic spatial optimization is redefining industrial racking engineering parameters.
Modern warehouse racking is no longer treated as simple passive metal shelving; in contemporary structural engineering codes (such as Eurocode 3, FEM 10.2.02, and US RMI MH16.1), free-standing tall pallet rack systems are classified as unbraced steel frameworks subject to severe seismic mass accelerations. When earthquakes strike, loaded pallets represent tremendous kinetic energy that must be safely dissipated without total column bucking or catastrophic beam detachment.
Our OEM manufacturing facility incorporates finite element analysis (FEA) computer simulation for all seismic-zone orders (such as the Pacific Ring of Fire spanning Latin America, Southeast Asia, and the Western United States). By deploying heavy-gauge flared base plates, high-tensile anchor bolts with specified pull-out shear ratings, dual-shear beam connectors with safety locks, and high-ductility diagonal cross-bracings, we ensure that the entire racking envelope can sustain dynamic ground accelerations without collapse.
Escalating land acquisition values, urban logistics decentralization, and severe labor shortages in cold-chain logistics have precipitated a massive migration from conventional 3.5m wide-aisle selective racking to dense semi-automated Radio Shuttle systems and fully autonomous automated storage and retrieval systems (ASRS). Standard manual lift truck aisles squander between 55% and 65% of cubic footprint solely on vehicular maneuvering.
In contrast, automated shuttle channels require only a single entry aisle or can be paired with high-speed automated cranes reaching heights of 30+ meters. In these systems, manufacturing precision is paramount: channel rail deflection must not exceed 1/1000th of span to ensure continuous laser sensor detection, seamless carrier docking, and battery energy conservation. HEDA’s shuttle rails are cold-rolled from 2.5mm high-yield galvanized steel with integrated optical retroreflector tracks.

Corrosion failure in warehouse steel structures represents a severe hidden catastrophic hazard. Atmospheric moisture, maritime coastal salt air (common in port logistics hubs), corrosive fertilizers, and constant sub-zero condensation in deep cold storage create aggressive micro-climates that degrade raw steel frames.
Our OEM manufacturing methodology combines multi-stage immersion pre-treatment with electrostatic dry-powder thermosetting:
Hot-Dip Galvanizing (HDG): In accordance with ISO 1461, structural steel members are immersed in molten zinc at 450°C, forming a series of zinc-iron alloy metallurgical layers with a minimum coating thickness of 65-85 μm. This delivers cathodic self-healing protection that withstands acidic, alkaline, and outdoor maritime atmospheres for decades without blistering or corrosion penetration.
How enterprise supply chain directors, procurement officers, and warehouse developers are mitigating geopolitical, logistical, and total life-cycle costs through strategic factory OEM partnerships.
Global procurement teams are shifting focus from initial purchase price per pallet position to 15-year TCO. Cheaper sub-gauge steel racking collapses under minor impact and degrades quickly. Certified Q355B cold-rolled profiles paired with replaceable column impact guards save up to 40% in structural maintenance and insurance premiums over a decade.
Skyrocketing ocean freight rates necessitate nested profile packaging designs. HEDA engineers optimize component dimensions—such as detachable welded beam connectors, split upright frames, and precisely nested bracings—maximizing container mass up to the allowable 26-28 metric tons per 40ft HQ, drastically cutting landed freight cost per pallet location.
Procurement contracts increasingly require suppliers to furnish complete Building Information Modeling (BIM) files (Revit, IFC) and 3D DWG architectural collision detection layouts. HEDA provides comprehensive engineering drawing submittals with static deflection graphs, permit approval packages, and anchorage stress reports before steel coil shearing begins.
Fast-evolving e-commerce fulfillment requires flexible storage formats. Leading logistics buyers favor bolted upright assemblies over permanently welded trusses. Standardized 50mm or 75mm pitch slot patterns allow warehouse managers to adjust beam levels dynamically or integrate multi-tier pick towers as throughput demands shift.
Authoritative engineering answers covering structural safety, factory OEM capabilities, international shipping logistics, and building code compliance.
We source primary hot-rolled steel coils exclusively from premier domestic mills conforming to Q235B and high-yield Q355B (equivalent to ASTM A36 and ASTM A572 Grade 50 / European S355JR). Every inbound steel master coil is accompanied by an authentic Mill Test Certificate (MTC) verifying carbon composition, yield strength, tensile yield (>355 MPa), and elongation percentages before cold-roll forming commences.
All load calculations conform to the international standard FEM 10.2.02 and RMI MH16.1 specifications. Under full uniformly distributed load (UDL), allowable beam vertical deflection is strictly restricted to $L/200$ (where $L$ is the clear span distance between uprights). For automated crane-served and ASRS systems, tolerances are stiffened to $L/300$ or $L/400$ to prevent robotic sensor trips and pallet drop hazards.
Yes. Our OEM division maintains specialized tooling dies for standard North American 2-inch teardrop punched holes (compatible with Interlake, Ridg-U-Rak, and SpaceRak patterns) as well as 50mm / 75mm European standard pitch systems. We can roll-form and match exact column cross-sections, beam connectors, and safety locking pins to interface seamlessly with your existing warehouse infrastructure.
To produce an optimized layout and load engineering calculation, we need: (1) Warehouse architectural drawings indicating clear ceiling heights, internal building columns, overhead sprinkler clearance, and floor slab thickness/compressive strength; (2) Pallet specifications including width, depth, overall height (including cargo overhang), and maximum gross load weight; (3) Forklift model, turning radius, and maximum mast lift elevation; and (4) SKU turnaround requirements (FIFO vs. LIFO).
Structural steel beams and uprights are bundled with heavy-duty PET straps, corner edge-protectors, and water-resistant polyethylene shrink-wrapping. Small accessories, connectors, base plates, and hardware bolts are packaged in wooden crates or palletized steel tubs with clear bilingual labels. Each shipping container features a detailed packing manifest cross-referenced to the 3D installation blueprint to speed on-site sorting.
Every commercial delivery includes 3D isometric assembly blueprints, step-by-step video installation walk-throughs, and torque specification charts for all anchoring hardware. For major capital projects, HEDA can dispatch bilingual mechanical installation supervisors to oversee local labor teams. All standard structural steel frames and beams carry a 5-year factory defect warranty.
