Top Trusted Longspan Shelving Manufacturer & Suppliers

While both systems use upright frames and horizontal beam profiles, Longspan Shelving is optimized specifically for medium-duty, hand-loaded storage applications ranging from 300 kg to 1,200 kg per beam level. It uses lighter cold-formed step-beam sections designed to support drop-in steel panels, wire mesh decks, or high-density particle boards. Selective Pallet Racking utilizes heavy-gauge box beams (typically 80–160mm in profile) designed to carry unitized forklift pallets weighing 1,000 kg to 4,500 kg per level, requiring wider aisle clearances for mechanical handling equipment.

UDL ratings comply strictly with EN 15512 structural standards. Load deflection calculations enforce that the maximum vertical deflection of any beam under maximum design capacity must not exceed L/200 (one-two-hundredth of the clear horizontal beam span). Safety factors of 1.5 against steel yield strength are calculated for both dead load and live load conditions. Every production batch is subjected to static hydraulic cycle tests in our Guangzhou testing facility prior to export dispatch.

We supply three primary deck configurations based on operational requirements:

• Galvanized or Powder-Coated Steel Panels: Ideal for sanitary, pharmaceutical, and high-wear automotive parts storage. Non-combustible, impervious to moisture and chemicals.
• Electro-Welded Wire Mesh Decking: Mandatory where fire safety sprinkler codes require water penetration through multiple rack tiers. Minimizes dust accumulation and improves lighting.
• High-Density Melamine / Plywood Boards: Cost-effective solution for dry retail distribution, lightweight packaging, and garment storage facilities.

For standard single-tier longspan shelving (under 3,000 mm upright height), a reinforced concrete industrial slab with a minimum compressive strength of 20–25 MPa (C20/25) and a thickness of 120–150 mm is recommended. Each upright footplate is secured using M10 or M12 mechanical expansion anchors. For high-bay longspan installations or multi-tier rack-supported platforms, our structural engineers evaluate slab thickness, sub-base compaction, and dynamic anchor pull-out ratings based on building foundation data.

Longspan systems are shipped as 100% knock-down components. Upright frames can be delivered pre-assembled or flat-packed as loose upright columns and bolted bracing bars. Beams are bundled in strapped master packs separated by protective timber dunnage. Small hardware, baseplates, and safety locking clips are packed in reinforced, palletized cartons. Through this 3D-modeled container loading methodology, a standard 40-foot High Cube (40HQ) container can accommodate between 18 to 26 metric tons of shelving materials, maximizing ocean freight value.

Yes, provided the initial upright frames were engineered with the requisite structural wall thickness (minimum 1.5mm to 2.0mm) and baseplate bolt configurations to support future vertical expansions. If phased warehouse expansion is anticipated, inform our design team during the initial CAD layout phase; we will size the primary upright section modulus to allow future catwalk brackets, intermediate floor beam ties, staircases, and handrail modules.

Every shipment from Guangzhou Heda Shelves Co., Ltd. includes an exhaustive export documentation dossier: Commercial Invoice, Packing List, Clean Bill of Lading, Certificate of Origin (Form E, CO, etc.), Mill Test Certificates (MTC) for raw steel coils, CE Declaration of Conformity (No. 2435-CPR-8605159), ISO 9001:2015 certificates, and detailed 3D step-by-step assembly drawings with numbered component lists.

Standard OEM production lead time for standard-specification longspan shelving orders (1 to 3 x 40HQ containers) is typically 14 to 20 working days from technical drawing sign-off and deposit confirmation. Custom profile roll-forming, non-standard RAL powder-coat colors, or integrated multi-tier mezzanine engineering typically requires 20 to 28 working days.
