Explore our field-proven industrial steel systems designed for manual picking lines, heavy bulk stacking, automated deep storage, and modular workshop organization.
Bridging the critical structural gap between light-duty retail boltless shelving and heavy structural selective pallet racks.
Modern distribution centers, third-party logistics (3PL) hubs, e-commerce fulfillment centers, and aerospace maintenance facilities face an accelerating challenge: inventory profiles have diversified beyond homogeneous pallet loads. While standard selective pallet racking excels at unitized full-pallet storage, it presents severe cubic inefficiencies when utilized for manual piece-picking, carton handling, or irregular machinery parts.
Long span shelving racks—also universally classified as wide-span shelving or medium-duty industrial storage racks—represent the definitive engineering solution for multi-tiered manual picking operations. Fabricated from certified cold-rolled structural steel (Q235B and high-yield Q355B), long span systems offer shelf spans reaching up to 2,700 mm without requiring intermediate vertical posts, granting completely unobstructed operator horizontal access.
At Guangzhou Heda Shelves Co., Ltd. (operating as HEDA Shelves since 2001), our engineering philosophy prioritizes structural integrity, dimensional repeatability, and absolute load safety. Backed by CE Certification (No. 2435-CPR-8605159) and an audited ISO 9001:2015 Quality Management System (No. 18624Q00169R0M), each upright frame, step beam, and shelf panel is engineered with safety factors exceeding 1.5 against ultimate structural yield limits.
Our long span systems comprise three primary structural components engineered to perform under cyclic dynamic loading:
Evaluating load capacity, picking velocity, space utilization, and investment amortizations.
| Storage System Type | Typical Load Rating (UDL) | Picking Accessibility | Floor Space Utilization | Compliance Standards | Primary Sector Application |
|---|---|---|---|---|---|
| HEDA Heavy Long Span Shelving | 300 – 1,000 kg / level | 100% Direct Manual | Medium – High (Up to 12m vertical) | AS 4084, FEM 10.2.02, CE | Automotive, E-commerce, 3PL Picking |
| Light-Duty Rivet / Boltless Shelves | 50 – 150 kg / level | 100% Direct Manual | Low – Medium (Max 3m vertical) | Commercial Light Grade | Office Archives, Small Retail Stock |
| Selective Pallet Racking | 1,000 – 4,500 kg / level | Forklift Dependent | High Cubic Utilization | AS 4084-2023, RMI MH16.1 | Unitized Pallet Logistics, Cold Stores |
| Multi-Tier Mezzanine Shelving | 300 – 800 kg / m² floor | Multi-Level Manual | Maximum (200%–300% floor gain) | ISO 9001, Building Codes | Apparel, Spare Parts Distribution |
| Radio Shuttle High-Density | 500 – 1,500 kg / pallet | Semi-Automated Lane | Ultra-High (Aisle Elimination) | EN 15512, Machinery Directive | FMCG, High-Volume Single SKU |
Note: All Uniformly Distributed Loads (UDL) are evaluated with a structural deflection ceiling of L/200 to L/250 in strict accordance with international finite element analysis (FEA) standards.
How intelligent automation, seismic mandates, ESG standards, and nearshoring are reshaping procurement.
Modern warehouses are phasing out static storage in favor of Autonomous Mobile Robot (AMR) compatibility. Future-proof long span shelving incorporates high-tolerance lower tunnel apertures, specialized floor guide rails, and high-visibility barcoding targets that enable co-robotic goods-to-person picking workflows.
Global logistics buyers face fluctuating freight and raw material rates. Advanced roll-forming technologies allow manufacturers to deploy micro-alloyed, high-yield Q355B cold steel profiles. This reduces total system deadweight by 12–18% while enhancing beam load-bearing stiffness and lowering cross-ocean container shipping costs.
Procurement specifications across Oceania, Japan, and the Americas now mandate documented dynamic earthquake resilience. In accordance with AS 4084 and NZS 1170.5, HEDA integrates portal beam ties, reinforced floor anchoring plates, and calibrated sway bracing calculated directly from site-specific soil and spectral acceleration parameters.
Guangzhou Heda Shelves Co., Ltd. provides vertically integrated manufacturing with total oversight from raw slit coils to port delivery.
Unlike trading entities, HEDA Shelves maintains complete manufacturing autonomy over our 30,000 m² production facility. With a dedicated technical workforce exceeding 300 professionals, our fabrication processes leverage automated CNC uncoiling, multi-station column punch pressing, precision cold-roll profile lines, and robotic CO&sub2; shielded welding bays.
Surface finishing is performed in an automated environmental pretreatment wash containing zinc phosphating stages, followed by thermosetting electrostatic powder coating. This guarantees a uniform coating thickness of 60–80 microns that easily surpasses 500-hour ASTM B117 salt spray tests, offering superior corrosion resistance even in coastal Australasia, Pacific Island, and Latin American maritime environments.
Cross-border supply chains demand flawless customs execution. All long span and heavy-duty shipments departing HEDA factories are packed into certified steel transport cassettes or ISPM-15 heat-treated export stillages. This completely mitigates quarantine holds enforced by regulatory bodies such as Australia's Department of Agriculture, Fisheries and Forestry (DAFF) and New Zealand's Ministry for Primary Industries (MPI).
Our project management division supplies complete documentation packs with every international bill of lading: preferential Certificates of Origin (supporting duty exemptions under ChAFTA / RCEP), mill test certificates confirming steel chemical composition, beam structural deflection calculations, and step-by-step CAD isometric assembly manuals.
Essential technical, structural, and logistics insights for warehouse directors, supply chain managers, and procurement officers.
