As warehouse square footage costs continue to escalate internationally, supply chain directors and facility planners are compelled to rethink traditional floor layouts. Longspan shelving bridges the critical operational void between light-duty slotted angle shelving and heavy-duty industrial pallet racking. Engineered specifically for manual handling, medium-to-bulk storage, and split-case distribution, longspan systems deliver high clear spans without the visual or spatial obstructions presented by intermediary bracing posts.
At the core of an enterprise-grade longspan installation is structural steel integrity. Utilizing high-tensile, cold-rolled structural steel coils (Q235B equivalent), our computerized roll-forming lines continuously stamp, profile, and cold-form upright columns and step beams. Upright frames are engineered as stiffened open omega profiles, distributing compressive axial stresses evenly across baseplates anchored directly to industrial reinforced concrete slabs. Beam-to-column connections rely on precision-tapered connector lugs with mechanical safety drop-pins, virtually eliminating dislodgement risks during aggressive warehouse replenishment cycles.

| Integrated Mezzanine Longspan | 1500 mm – 2200 mm | 300 kg – 600 kg + walkway loads | Drop-over steel decking with mesh backstops | Multi-tier manual consolidation, vertical order picking |
| Longspan Cantilever Hybrid | Custom cantilever arms | Up to 3,000 kg total arm load | Open arm or continuous timber deck | Structural tubing, lumber bundles, long PVC conduits |
Surface treatment constitutes another decisive pillar of reliability. Standard painted finishes routinely chip under daily inventory friction, leading to corrosion hot-spots in non-climate-controlled storage warehouses. To provide long-term durability, all components undergo a strict 10-stage pre-treatment regimen including chemical degreasing, acid pickling, and micro-crystalline phosphating prior to the electrostatic deposition of epoxy-polyester thermoset powder coatings. The cured finish exhibits superior resistance to impact cracking, chemical abrasives, and regional ambient humidity.
Forward-looking supply chains are transitioning from short-term transactional sourcing to data-backed, modular storage architectures designed for longevity, high modularity, and automated integration.
Modern longspan systems are increasingly pre-engineered to interface with Autonomous Mobile Robots (AMR) and Goods-to-Person (GTP) picking shuttles, requiring tighter tolerances and structural deflection ratios (L/200 or better).
Procurement directors are shifting emphasis away from rock-bottom spot steel prices toward structural lifespan, certified load guarantees, container-optimized nesting geometry, and rapid boltless installation architectures.
International risk insurers and municipal fire authorities enforce stringent guidelines regarding clear aisle widths, flue space compliance, and seismic dampening. Verifiable CE (EN 15512) and ISO certifications have become non-negotiable prerequisites.

Longspan shelving is specifically engineered for non-palletized manual hand-loading or split-case carton storage. While pallet racking typically spans 2300mm to 3600mm to support multi-ton palletized loads via forklift, longspan shelving utilizes lighter, high-rigidity step-beam profiles and solid shelf decks (steel panels, wire mesh, or timber) to support 200kg to 800kg per level with 100% direct picking access.
Our load capacities are engineered in accordance with EN 15512 specifications using finite element analysis (FEA) and empirical destructive testing. UDL assumes the operational payload is evenly distributed across the clear span of the shelf beam. Safety pins on each beam-to-column connector lock prevent accidental uplift, maintaining a safety design factor of at least 1.5 to 2.0 under continuous operational load.
Yes. Longspan upright frames can be structurally extended upwards to support intermediate multi-tier cat-walks or mezzanine walkways. This rack-supported configuration can double or triple usable floor surface area without requiring external building structural renovations, serving as an effective solution for high-density manual order sorting hubs.
All our longspan components undergo mechanical shot blasting, multi-stage acid pickling, and phosphating followed by an electrostatic epoxy-polyester powder coating cured at 180°C–200°C. For extreme humidity, outdoor canopies, or sub-zero blast freezer conditions, we supply continuous hot-dip galvanized finishes or pre-galvanized cold-formed steel coils that meet international anti-corrosion standards.
To prepare an accurate engineering layout, our team needs: (1) Architectural floor drawings indicating column grids, clear heights, and door locations; (2) Unit carton dimensions and weight profiles; (3) Preferred shelf tier heights and target vertical levels; and (4) Your required target shipping port and timeline. We typically return a 2D CAD plan and a detailed 3D proposal within 24 to 48 hours.
Upright frames are bundled flat with structural steel strapping and edge-protecting angle paper, while step beams are palletized on custom wood cradles with anti-friction wrapping. All component bundles are clearly marked with item codes corresponding directly to the provided assembly blueprint, ensuring rapid on-site sorting and straightforward installation.
