OEM/ODM Warehouse Pallet Storage Racks Factories & Exporter

In accordance with global structural standards (European FEM 10.2.02 and American ANSI/RMI MH16.1), the maximum permissible vertical deflection of a pallet rack beam under design load is L/200 (where L is the clear span distance between upright columns). For example, on a standard 2,700mm beam designed for two 1,000 kg pallets, the mid-span deflection must not exceed 13.5mm.

For automated installations (such as Radio Shuttle or ASRS systems), Heda designs to an even stricter threshold of L/300 to guarantee flawless sensor alignment and robotic cart docking.

For seismic-rated projects (such as our delivered installations across Ecuador, Chile, New Zealand, and Japan), we conduct Finite Element Analysis (FEA) factoring in local building codes (UBC, IBC, or Eurocode 8). Calculations account for the building's fundamental vibration period, ground acceleration factors, soil foundation coefficients, and seismic mass (typically 80% to 100% of the rated pallet weight).

Physical structural enhancements include upgrading upright steel thickness, replacing single anchors with dual heavy-duty expansion sleeves, adding horizontal and vertical top portal ties, and installing heavy-gauge back X-bracing to distribute lateral forces safely to the reinforced concrete floor slab.

Yes. As a premier OEM/ODM manufacturer, we maintain CNC tooling sets for the world’s most common punching styles. While our standard export line uses the versatile 50mm and 75mm European pitch, we regularly fabricate the 76.2mm (3-inch) pitch prevalent in Commonwealth markets, as well as teardrop punch styles required by North American operators.

During the RFQ phase, you can supply a physical sample or technical 2D drawing of your existing column and connector. Our engineers will match the hook configuration, steel gauge, and lock-pin positioning to ensure 100% backward compatibility.

For standard ambient warehouses, we utilize an automated multi-stage pre-treatment followed by thermosetting polyester powder coating baked at 200°C. However, in cold storage facilities (-18°C to -35°C), thermal contraction and humidity changes during defrost cycles can cause micro-fissures in standard coatings.

For cold-room projects, we offer two solutions: (1) Low-temperature flexible modified epoxy-polyester powder coats that remain elastic at sub-zero temperatures, or (2) Hot-Dip Galvanizing (HDG) to ISO 1461 specifications, where the structural steel is submerged in molten zinc at 450°C, providing a permanent 65–85 μm metallurgical barrier that prevents rust, flaking, or delamination even under heavy condensation.

International shipping efficiency is central to our OEM service. Upright frames are delivered knocked-down (frames assembled on-site via high-tensile Grade 8.8 bolts) or welded according to customer preference. Knock-down packing reduces ocean freight volume by up to 38% compared to pre-welded uprights.

Step beams are bundled in uniform steel-strapped packs with protective cardboard edging and heavy corrugated wrap. All painted contact points are separated by non-abrasive foam strips to eliminate transit vibration friction. Heavy baseplates, row spacers, and hardware bolts are packaged in solid wooden crates or reinforced metal cages with dedicated forklift skids for rapid container unloading.

To deliver an actionable engineering drawing and quotation within 8 hours, our structural team requires five key data points:

1. Warehouse Architectural Layout: Clear internal height, column locations, and dock door placements.
2. Pallet Load Specifications: Length, width, overall height (including cargo), and maximum gross weight per pallet.
3. Material Handling Equipment: Forklift model, maximum lifting height, turning radius, and aisle operating clearance.
4. Operating Environment: Ambient temperature, humidity, or cold-room parameters.
5. Regional Seismic / Slab Data: Concrete slab thickness, compressive strength (e.g., 25–30 MPa), and local seismic acceleration values.
