Engineered from certified Q235B high-tensile cold-rolled steel, our wide span and heavy-duty storage configurations deliver high beam deflection resistance, customizable beam spans from 1,200mm to 2,700mm, and loading capacities up to 3,000 kg per storage level.
In modern intralogistics architectures, Wide Span Shelving (frequently designated in engineering literature as Longspan Racking or Medium-Duty Hand-Loaded Racking) occupies the pivotal juncture between standard lightweight metal shelving and heavy-duty structural pallet racks. While standard industrial shelving is constrained by narrow bay lengths (rarely exceeding 1,000 mm) and load limits under 250 kg per shelf, wide span systems expand clear beam spans to 1,200 mm – 2,700 mm, providing unhindered lateral clearance tailored for non-palletized cartons, bulky automotive components, e-commerce order-fulfillment bins, and intermediate manufacturing assemblies.
From the perspective of material engineering and structural reliability (governed by standards such as EN 15512:2020, the RMI (Rack Manufacturers Institute) MH16.1, and AS 4084), the design of wide span shelving demands meticulous calculation of both ultimate limit states (ULS) and serviceability limit states (SLS). As an international tier-one exporter from Guangzhou, China, Guangzhou Heda Shelves Co., Ltd. controls structural tolerances via high-precision CNC roll-forming lines, utilizing cold-formed structural carbon steel (predominantly Q235B and Q355B according to GB/T 700-2006, equivalent to European S235JR and S355JR). The structural rigidity of our upright assemblies relies on an engineered omega profile featuring 8 to 12 cold-bent stiffening facets, which substantially elevates the radius of gyration ($r_x, r_y$) and dampens the risk of torsional-flexural buckling under sustained axial compressive loads.

A frequent operational failure observed in substandard wide span exports involves excessive mid-span beam deflection and connection tab fatigue. At HEDA Shelves, our step-beams and tubular box beams are formed with interlocking continuous seam welds and equipped with heavy-gauge 3-claw or 4-claw cold-stamped connectors. Each connector incorporates a spring-action zinc-plated safety locking pin to neutralize accidental beam dislodgement caused by manual lifting carts or errant warehouse machinery. When sizing wide span shelving for enterprise buyers, our structural engineers model finite element analysis (FEA) to confirm that beam deflection under a uniformly distributed load (UDL) remains strictly within Deflection $\le L / 200$, maintaining seamless ergonomic hand-picking and preventing permanent plastic deformation over decades of continuous cycle shifts.
Procurement directors and supply chain engineers must look beyond basic FOB steel pricing. Sourcing strategies for industrial shelving are undergoing a paradigm shift driven by smart warehouse automation, micro-fulfillment, and carbon-reduction initiatives.
Warehouse design is discarding rigid segregation between robotic aisles and manual shelving. Next-generation wide span frames are engineered with unobstructed floor-level clearance tunnels to allow Autonomous Mobile Robots (AMRs) and automated guided vehicles (such as the XBOT-AGV series) to travel directly underneath manual pick shelves, orchestrating goods-to-person replenishment without sacrificing vertical cubic storage.
With commercial industrial real estate costs climbing internationally across key distribution regions—from North American logistics corridors to South Asian metros like Bhiwandi, Gurugram, and Dhaka—procurement teams are shifting capital from new floor construction toward multi-tier wide span mezzanine platforms. High-load wide span uprights serve as the direct structural foundation for 2-tier and 3-tier catwalk floors, doubling or tripling usable fulfillment footprints.
Procurement compliance mandates greater resistance to humid, aggressive environments (e.g., tropical monsoon climates and coastal salt-mist zones). Outdated spray-paint techniques have been replaced by multi-stage pickling, iron-phosphating, and automated thermosetting electrostatic powder coating. This provides a minimum coating thickness of 60–80 microns, passing 500-hour ASTM B117 salt-spray standards while eliminating volatile organic compounds (VOCs).
High precision in storage equipment starts with comprehensive manufacturing control. We execute all transformation steps in-house within our 30,000 square meter Guangzhou facility, ensuring full batch traceability from certified structural coil to final container stowage.

Wide Span Shelving bridges the operational gap between light-duty manual shelving and full pallet racks. Standard rivet shelving is limited to beam spans under 1,000mm and loads up to 200 kg per tier. Pallet racking is designed for forklift operations with pallet loads from 1,000 to 4,000 kg. Wide span systems feature intermediate clear spans (1,200mm to 2,700mm) and shelf load capacities from 300 to 1,200 kg per level, making them ideal for heavy hand-loaded goods, open-carton picking, and multi-tier picking towers where forklifts are not required inside the aisles.
Our systems utilize cold-rolled structural steel certified to GB/T Q235B and Q355B, matching European S235JR / S355JR and ASTM A36 / Grade 50 standards. All beam sizing calculations and upright axial load capacities follow European racking standards EN 15512:2020, the US RMI MH16.1, and Australian AS 4084. Mill certificates with chemical and mechanical test results are provided for each production heat batch.
We provide three primary decking styles: (1) Pre-galvanized or powder-coated drop-in steel panels, which offer high durability, fire resistance, and easy cleaning; (2) Electro-galvanized wire mesh decking with welded reinforcement channels, optimal for open overhead sprinkler penetration and dust-free ventilation; and (3) High-density particleboard or melamine-faced MDF panels (18–25mm), common for manual picking of apparel, hardware, and automotive spare parts.
Prior to coating, steel members undergo continuous 8-stage chemical immersion including degreasing, acid pickling, rinsing, and zinc-iron phosphating. Automated electrostatic application of high-adhesion polyester epoxy powder follows, baked at 200°C to achieve a durable 60–80 µm finish. For open-sided structures, maritime humidity, or cold-storage environments, full hot-dip galvanizing (HDG) per ISO 1461 can be specified during preliminary engineering.
Standard production runs require 15 to 25 days depending on total project tonnage. Our dedicated container loading engineering creates customized 3D packing models for every order. Upright frames are nested, beams bundled in steel strapping, and decking wrapped in corrugated corner protectors to fill 90%–94% of container cube space, minimizing freight costs per metric ton.
Yes. Our heavy-gauge wide span upright columns (such as the 60x50mm and 80x60mm profiles) can be integrated with mezzanine beams, steel floor decking, staircases, and OSHA/CE-compliant handrails. This creates an engineered multi-tier catwalk picking platform with floor loading capacities from 300 to 800 kg/m², avoiding the need for an independent structural steel mezzanine.
