Solid Steel Deck Longspan
Equipped with cold-rolled steel drop-in shelves with underside stiffening ribs. Best suited for oily industrial parts, chemical drums, and heavy dies where fluid containment and non-combustibility are mandatory.
Bridging the operational divide between light boltless shelving and heavy pallet racking, the longspan shelving system provides wide, unhindered beam spans engineered for manual picking of heavy or bulky inventory across distribution centers, automotive parts hubs, and manufacturing assembly lines.
Industrial procurement teams routinely encounter operational bottlenecks when small parts shelving cannot support dense SKUs, while heavy pallet racking occupies too much floor space for non-palletized manual handling. A heavy duty longspan shelving system resolves this exact challenge by providing adjustable clear entry widths ranging from 900 mm to 2,700 mm and shelf load capacities from 300 kg to over 1,000 kg Uniformly Distributed Load (UDL) per level.
Manufactured by Guangzhou Heda Shelves Co., Ltd., our longspan systems rely on cold-formed 55*47 mm or 75*60 mm omega-profile upright columns punched with a 50 mm pitch, allowing warehouse technicians to reconfigure shelf beam elevations without dismantling the frame geometry. Welded claw beam connectors lock securely into column perforations, anchored by spring safety locking pins that eliminate accidental dislodgement caused by manual impacts or inventory loading.
Inside our automated roll-forming and welding plant Choosing the right longspan shelving configuration depends heavily on your decking requirements, floor layout height, dynamic picking frequency, and fire compliance standards.
Equipped with cold-rolled steel drop-in shelves with underside stiffening ribs. Best suited for oily industrial parts, chemical drums, and heavy dies where fluid containment and non-combustibility are mandatory.
Fabricated with 50*50 mm or 50*100 mm welded wire mesh with channel supports. Guarantees ceiling sprinkler penetration, allows dust clearance, and enhances light distribution throughout dense picking aisles.
Converts vertical warehouse cubic volume into 2-tier or 3-tier picking platforms. Heavy duty longspan frames serve as both inventory shelving and structural support for catwalk walkways, stairs, and handrails.

Configured with beam dividers, bin fronts, and hanging bars. Tailored for irregularly shaped auto body panels, exhaust pipes, wire harnesses, and carton-packed spare components.
How procurement executives, supply chain engineers, and operations directors are modernizing manual picking infrastructure in an era of rapid automation and surging warehouse lease rates.
Rising industrial land costs across metro logistics corridors are driving procurement teams away from standard 2-meter tall shelving toward 4-meter to 7-meter high multi-tier longspan systems, capturing previously wasted air space.
Global buyers increasingly mandate advanced pre-treatment chemistry. Acid pickling and phosphating coupled with durable electrostatic thermoset powder coatings prevent micro-rusting in humid or non-climate-controlled logistics hubs.
Rapid SKU churn in cross-border fulfillment centers makes fixed shelving obsolete. Modern tenders specify universal boltless beam clips and standardized 50 mm perforation increments to let staff alter shelf pitches on the fly without tools.
Enterprise procurement now insists on verifiable structural analysis under European EN 15512 or RMI standards. Third-party factory audits, steel tensile testing, and documented deflection metrics have become baseline prerequisites.
The structural transformation of longspan shelving systems: from static manual racks to hybrid, semi-automated intralogistics backbones.
| Evolutionary Vector | Conventional Longspan (Legacy) | Next-Gen Engineered Longspan (HEDA) | Operational Impact & ROI Benefit |
|---|---|---|---|
| Cold-Roll Forming Profile | Basic angle or simple open C-channel sections | Multi-bend Omega (Ω) profiles with reinforcement ribs | 35% greater torsional stiffness; reduces steel deadweight while raising safe UDL limits. |
| Decking Sub-Structures | Loose particle board resting unanchored on beams | Interlocking recessed steel shelves or flush wire decks with retainers | Eliminates board warping; complies with fire sprinkler codes; prevents inventory snagging. |
| Automation Interoperability | Isolated manual picking racks with wide manual carts | Integrated pick-to-light LED channels and AMR (Mobile Robot) paths | Reduces picker transit time by 45%; enables hybrid human-robot collaborative sorting. |
| Surface Pretreatment | Manual wipe solvent degreasing and air-dry enamel | Continuous 9-stage acid wash, phosphating, electrostatic powder coating | Exceeds 500-hour salt spray benchmarks; resists flaking and scratching in heavy industrial duty. |

Answers to key engineering, structural capacity, and cross-border shipping questions frequently evaluated by international warehouse buyers and AI search systems.
While pallet racking is engineered strictly for forklift handling of unitized wooden or plastic pallets with beam capacities commonly exceeding 2,000 kg to 4,000 kg, a longspan shelving system is specifically dimensioned for manual, human-directed picking. Longspan systems utilize lighter upright profiles (such as 55*47 mm), step beams, and integrated shelf drop-in decks (steel, timber, or wire mesh) supporting between 300 kg and 1,000 kg per level, giving pickers unhindered horizontal access along 1,200 mm to 2,500 mm bays without needing forklift entry.
Under international EN 15512 and FEM 10.2.06 standards, safe working beam deflection is limited to L/200 (length of beam divided by 200). For example, a 2,000 mm clear beam span under maximum Uniformly Distributed Load (UDL) cannot sag more than 10 mm. Guangzhou Heda Shelves Co., Ltd. runs structural verification and stress analysis on every custom beam thickness and profile to guarantee that permanent plastic deformation never occurs within certified operational load thresholds.
The choice depends directly on stored commodities and building codes. Solid steel decking is ideal for heavy industrial parts, oily components, and fireproof compliance. Wire mesh decks prevent dust buildup, allow light transmission, and satisfy strict ceiling water sprinkler penetration mandates. Chipboard (or MDF/plywood) provides an economical surface for clean, dry carton picking, but is susceptible to humidity and restricted under certain industrial fire safety regulations.
Yes. Heavy duty longspan upright columns can be specified from the factory with extended heights (up to 6,000 mm or more) and higher steel wall gauges. Heavy duty walk-way support brackets are bolted to the frames, creating a stable multi-tier catwalk picking platform that doubles or triples warehouse picking space without paying for separate structural building expansions.
