Engineered for intralogistics distribution hubs, 3PL fulfilment centres, e-commerce packing floors, and high-bay industrial operations. Precision roll-formed using certified structural Q235B and Q355B cold-rolled steel with electrostatic polymer coatings.
When specifying industrial pallet racking and order-fulfillment workstations, material yield strength, connector mechanics, seismic baseplates, and deflection limits dictate warehouse longevity, worker ergonomics, and regulatory audit compliance.
We utilize prime cold-rolled steel coils matching Q235B (yield strength ≥ 235 MPa, tensile strength 370–500 MPa) and heavy-duty Q355B (yield strength ≥ 355 MPa) specifications. Upright columns undergo continuous multi-roller cold profiling, cold-work hardening the steel corners to increase cross-sectional moment of inertia by up to 22% compared to conventional press-braked channels.
Under EN 15512 and FEM 10.2.02 codes, the maximum allowable vertical beam deflection is L/200 (where L is the clear span length). For robotic and AGV/AMR picking interfaces, our engineers tighten manufacturing tolerances to L/300. Robotic dual-seam welded beam connectors feature 4 or 5 interlocking tapered claws with heavy-gauge safety locking pins preventing accidental dislodgement during high-speed forklift handling.
Unlike monolithic warehouse racks, pallet rack workstations combine multi-tier heavy storage overhead (carrying 1,000–3,000 kg pallets) with integrated lower pick-and-pack stations. Incorporating LED task lighting, cantilevered carton shelves, roller slide conveyors, pneumatic drop-drops, and ESD-safe steel worktops, our hybrid frames eliminate worker reach fatigue and accelerate picking cycle times.

Global supply chain directors and third-party logistics (3PL) infrastructure developers are transitioning from passive storage steel to agile, automated, and sustainable fulfillment architecture.
Procurement teams are prioritizing rack upright bases designed with recessed flanged gussets and tunnel underpasses. Rather than relying solely on high-reach counterbalance forklifts, ground tiers are engineered for autonomous mobile robots (AMRs) to pick pallet loads directly beneath the workstation platform.
Rigid, welded custom tables are being replaced by boltless slotted upright profiles with universal 50mm pitch patterns. This enables logistics operations to reconfigure packing stations, overhead carton flow tracks, and monitor mount arms in under 30 minutes without hot work permits or facility downtime.
European and North American procurement mandates now penalize heavy solvent-borne finishes. Modern specifications demand heavy-metal-free, RoHS-certified electrostatic powder coatings with 98% overspray reclamation, along with verified mill test certificates tracking recycled steel percentages.
Leading warehouse developers require full Building Information Modeling (BIM) files prior to procurement. Supplying direct Revit, DWG, and STEP assets allows engineers to stress-test rack-building clearances, sprinkler pipe integrations, and seismic load distributions before steel coil slitting starts.
Established in 2001, Guangzhou Heda Shelves Co., Ltd. has grown from a specialized metal processing unit into an international powerhouse in storage engineering. Headquartered in Guangzhou, China, our 30,000 square meter intelligent manufacturing facility operates with over 300 skilled technicians, certified structural engineers, and robotics specialists.
We deliver complete end-to-end manufacturing sovereignty: continuous roll forming, automated robotic punching, 3D laser tube cutting, multi-station automated welding, and an automated continuous dual-line electrostatic powder coating facility with zero intermediate outsourcing.
Every pallet rack beam, column upright, and workstation bracket passes through our audited ten-stage production sequence to guarantee dimensional precision and load repeatability.
Mill certificate verification, ultrasonic thickness profiling, and chemical spectrometry of incoming coils.
High-speed hydraulic CNC slitting machines slit master coils with edge burr tolerances < 0.03mm.
Automated continuous multi-axis punch presses stamp 50mm / 75mm teardrop and diamond pitch holes.
18-pass progressive cold roll forming lines produce omega upright profiles without residual stress.
Interlocking seam step-beam roll forming creates reinforced box structures for zero beam twist under load.
Dual-station robotic Panasonic GMAW welders fuse 4-claw beam connectors with structural penetration.
Automated rotary descaling and weld spatter buffing ensure smooth surfaces free of micro-cracks.
Degreasing, zinc-phosphating, and deionized water rinsing prepare the steel substrate for maximum bonding.
GEMA automatic powder gun reciprocators apply 70–90μm epoxy-polyester cured at 200°C baking tunnel.
Protective foam wrapping, steel strapping, corner guards, and cubic-optimized container racking pallets.
In-depth technical and commercial answers tailored for procurement managers, structural inspectors, and international logistics directors.
We provide comprehensive structural design documentation including FEA (Finite Element Analysis) reports, STAAD.Pro structural models, beam deflection curves referencing EN 15512 or ANSI MH16.1, and certified factory load tables signed by licensed structural engineers for presentation to local municipal inspectors.
Yes. We manufacture customized beam clear spans (e.g., 2,700mm for three EUR pallets, 2,300mm for two ISO pallets, or 96"/108" spans for US GMA pallets) along with frame depths from 800mm to 1,200mm, fitted with wire mesh decking or cross-support bars to adapt to heterogeneous pallet standards.
For high seismic risk facilities, we implement heavy-duty seismic baseplates (up to 20mm thickness), heavy-wall cold-rolled uprights with enlarged cross-sections, back-to-back reinforced frame spacers, vertical tower bracing sets, and concrete anchor bolt penetrations exceeding 160mm embedment depths.
Standard custom fabrication requires 15 to 25 days depending on tonnage. Sea transit from Guangzhou/Shenzhen port averages 18–25 days to North America (West Coast), 28–35 days to European ports (Rotterdam, Hamburg, Valencia), and 12–16 days to Southeast Asian and Middle Eastern destinations.
Direct sourcing delivers a 25% to 40% capital equipment cost reduction by removing intermediate margin layers. Crucially, direct factory engineering allows custom component fabrication (non-standard column heights, specific RAL powder coatings, tailored pitch spacing) rather than forcing projects into pre-stocked regional SKUs.
For sub-zero cold chain operations (down to -30°C) or coastal humidity, we supply hot-dip galvanized steel components (coating thickness ≥ 75 μm conforming to ISO 1461) or specialized epoxy zinc-rich undercoats beneath the outer polyester powder coat, passing 1,000+ hour neutral salt-spray testing (ASTM B117).
Every shipment is packaged with an itemized numbered packing list, color-coded 3D exploded assembly diagrams, detailed anchor torque specifications, floor loading footprint distribution maps, and digital video installation walkthroughs. Onsite supervision is available for mega-facilities upon request.
Yes. Over 40% of our production capacity is dedicated to private-label OEM partnerships. We offer custom punching dies (matching Dexion, Stow, Mecalux, or Tear Drop profiles), branded load notices, customized carton printing, and dedicated container stowage optimizing local distribution logistics.
Our nesting packaging engineers arrange structural upright frames and box beams with protective corrugated buffers, precision wood cribbing, and heavy-gauge polyester strapping. A standard 40HQ container routinely accommodates 22 to 26 metric tons of racking components without metal-to-metal rubbing or transport distortion.
HEDA Shelves provides a comprehensive 5-to-10-year manufacturer structural warranty against steel material defects, welding delamination, and premature coating failure. When operated within rated load limits and maintained in accordance with EN 15635 guidelines, our racking installations possess a verified service life exceeding 25 years.
