Explore our certified range of custom cold-formed structural steel racks, adjustable high bay configurations, and specialized logistics carriers built to maximize cubic utilization.
Selecting the optimal structural profile requires balancing pallet velocity, clear building height, forklift aisle requirements, and automated handling integration (AS/RS). Our application engineering team breaks down core configurations below.
Engineered for warehouse clear heights from 10 to 18 meters, VNA high bay racking reduces operational aisle widths down to 1.6 - 1.8 meters, delivering an immediate 45% footprint reduction compared to conventional selective bays. Wire-guided or rail-guided turret trucks maximize retrieval cycles while maintaining 100% SKU selectivity.
By pairing high bay vertical uprights with autonomous motorized pallet shuttles, shuttle high bay racking eliminates internal forklift transit within deep storage lanes. Running up to 40 meters deep per lane, this semi-automated architecture guarantees superior throughput across both FIFO and LIFO inventory models.
In clad-rack engineering, the racking system itself forms the structural framework of the entire facility, supporting both side wall panels and roof cladding along with integrated wind, snow, and seismic dynamic loads. Heights can exceed 30 to 40 meters, served by automated stacker cranes (AS/RS).

Global logistics managers and enterprise procurement teams are pivoting from transactional spot purchasing to long-term structural partnerships. Three core macro procurement shifts are transforming the high bay racking sector.
Warehousing operations face steep labor inflation and acute floor-space constraints. Buyers no longer specify simple static racks; they mandate "automation-ready" racking systems. This requires high-precision beam punchings, laser-verified column upright straightness (under EN 15620 Class 100 tolerances), integrated optical reflector mounting points, and floor rail anchoring ready to accept Automated Guided Vehicles (AGVs) and Autonomous Mobile Robots (AMRs).
With corporate ESG mandates and the EU Carbon Border Adjustment Mechanism (CBAM), European and North American buyers are evaluating manufacturers on embodied carbon per metric ton of steel. Sourcing shifts toward tier-1 mills utilizing electric arc furnace (EAF) steel, scrap metal blends, and heavy-metal-free electrostatic powder coating finishes that carry transparent Environmental Product Declarations (EPDs) and full RoHS validation.
Supply chain disruptions have highlighted the vulnerabilities of relying on regional middleman brokers. Tier-1 buyers and racking distributors are forging direct OEM/ODM alliances with fully vertical Asian manufacturing centers. Direct factory collaboration delivers free in-house structural engineering (CAD & 3D BIM), customized roll-forming profile options, private-label brand packaging, and container loading optimization that cuts ocean freight overhead by up to 22%.
Modern high bay racking relies on complex material science, non-linear finite element analysis (FEA), and continuous roll-forming innovation to achieve greater vertical heights with optimized steel mass.
By transitioning from conventional mild steel (235 MPa) to advanced cold-formed micro-alloyed steels such as Q355B, S355MC, and high-tensile structural grades up to 420 MPa, our roll-formed upright columns achieve up to 35% higher moment capacity without adding dead-weight to slab foundations. Continuous 30-station roll-forming lines preserve structural yield stress across every bend radius.
High bay systems operating in seismic-prone zones (such as Southern Europe, Pacific Rim, or Latin America) demand full adherence to Eurocode 8 and RMI MH16.1 specifications. Modern designs employ dynamic response-spectrum structural analysis, reinforced double-flange baseplate shoes, heavy diagonal K-bracing, and sacrificial friction damping connectors engineered to dissipate kinetic energy during severe ground accelerations.
Smart high bay installations are beginning to feature embedded strain sensors, acoustic emission detectors, and tilt sensors built into critical upright footplates. Connected to warehouse management systems (WMS), these IoT arrays log real-time beam deflections, detect unrecorded forklift impacts immediately, and alert site maintenance supervisors before localized structural deformation creates safety hazards.
Established in 2001, Guangzhou Heda Shelves Co., Ltd. operates a continuous 30,000 square meter intelligent manufacturing complex powered by over 300 experienced technical, structural, and production specialists. With a proven monthly steel conversion output of 30,000 metric tons, we provide seamless end-to-end delivery—from custom structural calculation and BIM layouts to high-speed roll forming, automated robotic welding, and seaworthy export staging.
Serving over 10,000 completed warehouse logistics projects worldwide, we operate as the OEM/ODM backbone for established European distributors, EPC contractors, and industrial procurement consortia who require verified safety compliance, strict dimensional tolerances, and direct factory pricing.
Direct technical and logistical answers prepared by our structural engineering department to streamline your project vetting process.
Our structural engineering designs strictly comply with European standards EN 15512:2020 (Steel static storage systems - Specification of beam pallet racking), EN 15620 (Tolerances, deformations and clearances), and FEM 10.2.02 codes. For seismic regions, we calculate structures in accordance with Eurocode 8 (EN 1998) or American ANSI/RMI MH16.1 specifications. Project-specific calculation reports and PE stamps are available upon request.
Yes. Upright frame depths (typically 1,100 mm for standard Euro pallets) and beam lengths (typically 2,700 mm for 3 Euro pallets or 3,600 mm for 4 Euro pallets) are customized to provide optimal 75 mm to 100 mm clearances between pallets and uprights. For variable pallets (such as 1200 x 1000 mm ISO or four-way entry skids), we integrate cross-pallet support bars, drop-over wire decking, or steel shelves.
AS/RS installations demand strict compliance with EN 15620 Class 100 / Class 200 guidelines. We enforce mill-certified steel strip thickness, multi-stage cold roll-forming with optical laser alignment, automated servo-controlled punch indexing (±0.2 mm cumulative pitch error across 12 meters), and specialized welding jigs to guarantee that upright vertical plumbness and beam deflection remain well within the 1/200th to 1/350th design threshold.
Standard factory production lead time ranges between 15 to 30 working days depending on total project tonnage and surface treatment specifications (powder-coated vs. pre-galvanized or hot-dip galvanized). Ocean shipping from Guangzhou / Shenzhen port to primary European destinations (Rotterdam, Hamburg, Antwerp, Valencia) averages 28 to 35 days, with direct container loading and customized bundle packaging to prevent transit abrasion.
To formulate an optimized proposal, our engineering team requires: (1) Architectural floor plan (DWG/PDF) indicating building columns, overhead clearances, and fire sprinkler/duct levels; (2) Pallet specifications (width, depth, overall height including cargo, and maximum gross weight); (3) Material handling equipment (MHE) turning radius and maximum lift height; and (4) Floor slab technical specification (load-bearing capacity per square meter and slab thickness).
Yes, OEM/ODM contracts constitute a significant portion of our international output. We can roll-form proprietary upright and beam profiles, punch customer-specific pitch slots (e.g., 50 mm, 75 mm, 76.2 mm), apply custom RAL corporate powder coating colors, affix OEM laser-cut brand labels, and package components in distributor-branded export crates ready for direct site distribution.
