Longspan shelving bridges the gap between standard shelving and pallet racking, offering wide spans for bulk storage without requiring pallet handling equipment. ZEOU Metal manufactures industrial shelving systems including longspan configurations for diverse storage needs.
What Is Longspan Shelving?
Longspan shelving (also called wide-span shelving) is a structural shelving system with beam spans typically 4-12 feet wide. The Wikipedia article on shelving explains different shelving categories. Longspan systems use heavy-duty steel beams and posts with various decking options. They are designed for manual access without forklifts — items are placed and retrieved by hand or with carts. Load capacities range from 1,000-4,000 lbs per level, filling the gap between standard shelving (500-1,000 lbs) and pallet racking (4,000-10,000+ lbs).
Longspan vs Standard Shelving
Longspan shelving differs from standard shelving in three key ways: Span width — longspan spans 6-12 feet vs 3-4 feet for standard shelving. Load capacity — longspan supports 1,000-4,000 lbs per level vs 500-1,000 lbs for standard. Beam adjustment — longspan uses bolted beam connections for high rigidity vs clip-in shelves. Longspan is ideal for bulky items that require wider openings and higher weight capacity than standard shelving can provide.
Longspan vs Pallet Rack
Pallet rack is designed for palletized loads handled by forklifts, with spans of 8-12 feet and capacities of 4,000-10,000+ lbs per level. Longspan shelving is designed for manual handling of case quantities and bulk items. Longspan typically uses lighter-gauge steel and shallower beam depths. Longspan can be assembled without tools in many configurations. Longspan is more economical than pallet rack for applications below 4,000 lbs per level where forklift access is not required.
Beam Types
| Beam Type | Span Range | Load Range | Best For |
|---|---|---|---|
| Box beam (rectangular) | 6-10 ft | 1,000-2,000 lbs | General storage |
| Step beam (L-shaped) | 6-12 ft | 1,500-3,000 lbs | Heavy loads |
| Reinforced box beam | 8-12 ft | 2,000-4,000 lbs | Maximum capacity |
Decking Options
Particle board deck: economical, smooth surface, water-sensitive. Wire mesh deck: fire sprinkler-compatible, visible debris, good air circulation. Steel sheet deck: high strength, flat surface, oil-resistant. MDO plywood deck: moisture-resistant for cooler environments. Each decking type serves different cleanliness, weight, and fire code requirements. ZEOU’s wire shelving expertise extends to wire deck options for longspan systems.
Load Capacities
Capacity depends on span, beam size, and deck type. A 6-foot span with reinforced beams supports approximately 3,000 lbs. An 8-foot span with standard beams supports approximately 2,000 lbs. A 12-foot span with heavy beams supports approximately 4,000 lbs. Deflection under full load should not exceed L/150 of the span. Always verify load ratings with the manufacturer. Uneven loading reduces capacity — distribute weight evenly across beams.
Assembly and Installation
Longspan shelving is typically assembled with bolted connections (as opposed to clip-in connections of standard shelving). Bolts provide higher rigidity and prevent accidental dislodgement. Most systems can be assembled with basic hand tools. Anchoring to the floor is recommended for seismic areas and loads exceeding 1,500 lbs per level. The OSHA storage regulations require proper anchoring for industrial shelving systems.
Best Applications
Retail backroom storage, wholesale distribution centers, warehouse bulk item storage, manufacturing material staging, auto parts warehousing, furniture storage. Longspan shelving is the preferred choice for any facility storing case quantities, bulk boxes, or oversized items that need manual access without forklift dependency.
Accessories
Back panels prevent items from falling behind shelves. Row spacers stabilize adjacent rows. Column protectors guard against impact damage. Shelf dividers organize items within shelves. Drawer units for small parts integration. Label holders for location identification. ZEOU Metal offers a full range of commercial shelving accessories for longspan systems.
FAQ
What is the difference between longspan shelving and pallet rack?
Longspan shelving is designed for manual access with capacities up to 4,000 lbs per level. Pallet rack supports palletized loads over 4,000 lbs handled by forklifts.
What is the maximum load for longspan shelving?
Typically 1,000-4,000 lbs per level depending on span, beam size, and deck type. Verify with manufacturer load tables for your specific configuration.
Can longspan shelving be adjusted?
Yes. Beam positions are adjustable in 2-inch increments. Decking can be repositioned as beams are moved. Most systems allow reconfiguration without replacing components.
Does longspan shelving require floor anchoring?
Anchoring is recommended for loads over 1,500 lbs per level or in seismic zones. Light to medium loads may not require anchoring depending on local codes.
