High-Density Manual Storage with Zero Floor Wastage
Multiply Usable Footprint 300% Vertically
When enterprise warehouses face SKU fragmentation, carton-picking bottlenecks, and intermediate load challenges that exceed conventional light shelving but do not warrant heavy forklift pallet racking, the industrial Longspan Shelving System provides the optimum structural balance.
An industrial Longspan Shelving System is a heavy-duty, boltless, medium-to-heavy load modular storage framework engineered primarily for manually loaded, un-palletized merchandise, carton cases, tote bins, and irregularly shaped components. Bridging the operational divide between light-duty slotted angle shelving (sub-150 kg per level) and full-scale selective pallet racking (1,000 kg to 4,000 kg per level), longspan systems deliver load capacities ranging from 200 kg to 800 kg per beam level across wide, unencumbered horizontal spans of 1,200 mm to 2,700 mm.
Manufactured by Guangzhou Heda Shelves Co., Ltd. from certified high-tensile Q235B cold-rolled structural steel, our systems utilize precision omega-profile upright columns punched on 50mm increments. This enables tool-free, instantaneous vertical beam adjustments. The structural beams utilize step-beam or tube-beam profiles engineered with heavy-duty safety locking pins that mechanically eliminate accidental beam dislodgement under dynamic warehouse handling.
Our longspan configurations are engineered strictly to the FEM 10.2.06 and EN 15512 structural standards. Guangzhou Heda Shelves Co., Ltd. calibrates all beam calculations against a deflection limitation of L/200 under Uniformly Distributed Load (UDL). This ensures zero structural sagging, protecting personnel ergonomics while extending product service life beyond 15 years.

Guangzhou Heda Shelves Co., Ltd. provides customized industrial longspan configurations tailored to dynamic storage requirements, product formats, and material handling workflows.
High Durability Steel Decking Longspan System: Features roll-formed ribbed galvanized or powder-coated steel shelf plates with underlying stiffening ribs. Best suited for oily industrial machinery spares, chemical containers, and heavy paint drums requiring sanitary wiping.
NFPA Compliant Wire Mesh Deck Longspan System: Heavy-gauge welded wire grids drop directly into step beams. Eliminates dust accumulation, maximizes overhead lighting penetration, and satisfies rigorous commercial warehouse fire sprinkler compliance.
3X Space Utilization Multi-Tier Catwalk Longspan Mezzanine: Transforms warehouse vertical cubic air volume into 2 to 4 operational picking floor tiers supported directly by upright frames, integrating staircases, handrails, and pallet drop gates.
Cost Efficient Timber / Plywood Longspan System: Utilizes high-density chipboard or marine-grade laminated ply resting securely within stepped beam ledges. Ideal for e-commerce apparel distribution, general consumer packaging, and dry archiving.
Global logistics operators are moving beyond static storage. How are next-generation procurement priorities reshaping industrial longspan racking investments?
01 Modern fulfillment hubs are retrofitting longspan racking aisles with AMR docking zones and automated carton-picking shuttles. Clear bay spans and precision base-plate alignment ensure robotic pickers maneuver with millimeter-level repeatability.
02 Global procurement teams prioritize carbon-neutral supply chains. Guangzhou Heda Shelves Co., Ltd. leads with low-scrap CNC roll forming, recyclable heavy-gauge Q235B steel, and lead-free thermoset powder coats with near-zero VOC emissions.
03 Skyrocketing industrial real estate valuations in major logistics corridors make horizontal expansion impossible. Shelving-supported multi-tier catwalk platforms have become the fastest-growing investment segment for urban distribution centers.
04 Enterprises are embedding IoT load-cell sensors directly beneath longspan beam clips. These sensors provide real-time weight telemetry to warehouse management systems (WMS), preventing point-load overstress and triggering real-time safety warnings.
Since 2001, Guangzhou Heda Shelves Co., Ltd. has established itself as an authoritative leader in warehouse storage systems engineering.

Get CatalogThe core differences center on handling methods, clear span dimensions, and loading dynamics. Longspan Shelving Systems are optimized for manual hand-loaded item picking, carton boxes, and open tote containers. They feature clear horizontal beam spans up to 2,400mm and safe working loads of 200kg to 800kg per level, supported by solid steel, wire mesh, or timber drop-in shelves. In contrast, Pallet Racking is engineered for mechanized reach truck and forklift access, holding 1,000kg to 4,000kg per level on standardized wooden or plastic pallets without integrated solid continuous decks.
Uniformly Distributed Load (UDL) assumes the total cargo weight is evenly spread across the entire shelf surface area rather than concentrated at a single point. Guangzhou Heda Shelves Co., Ltd. designs step-beam profiles and shelf plate stiffeners according to FEM 10.2.06 standards with a 1.5 safety factor, ensuring beam deflection does not exceed 1/200th of clear span length under maximum rated load.
Standard paint finishes can peel when exposed to high humidity and ocean freight transit. Guangzhou Heda Shelves Co., Ltd. subjects every steel component to an automated multi-stage pre-treatment line: chemical degreasing, ultrasonic water rinsing, acid pickling to remove scale, and phosphating. Finally, a 60–80μm electrostatic epoxy-polyester powder coat is cured at 180°C–200°C, creating a resilient anti-corrosion barrier.
Yes. Heavy-duty longspan upright columns (such as our 80×60×2.0mm profile) can serve as structural load-bearing vertical pillars for multi-tier mezzanine catwalk platforms. Floor channel beams, staircases, grating walkways, and edge safety handrails mount directly to spliced upright columns, multiplying picking floor area up to 300% without structural building alterations.
Standard factory production lead time is typically 12 to 18 working days depending on total container volume and customized RAL color choices. We ship from Guangzhou and Shenzhen ports, with ocean transit times as fast as 2 to 5 days to Vietnam, 3 to 5 days to the Philippines, 5 to 7 days to Thailand and Singapore, 6 to 8 days to Malaysia, and 7 to 10 days to Indonesia.
