OEM/ODM Galvanized Pallet Racking Suppliers & Exporters

Hot-Dip Galvanizing (HDG, conforming to ISO 1461 or ASTM A123) takes place after the steel component has been cut, punched, and welded. The complete fabricated beam or upright is submerged into a molten zinc bath at approximately 450°C. This produces a metallurgically bonded multi-layer iron-zinc alloy coating with a thickness of 55 µm to 85 µm (390–610 g/m²), protecting all inner hollow channels and laser-cut perforations. Pre-galvanized components (conforming to EN 10346) are roll-formed from steel coils that were already galvanized at the mill, with a thinner zinc layer of 15 µm to 25 µm. When pre-galvanized coils are punched or sheared during rack manufacturing, the cut edges rely solely on lateral galvanic migration for edge protection. For aggressive C4/C5 environments and heavy-duty cold storage, post-fabrication Hot-Dip Galvanizing delivers superior durability.

In sub-zero conditions, conventional painted steel racks face severe mechanical degradation. Condensation from freeze-thaw cycles penetrates microscopic paint pores, freezing and expanding to pop the paint film off the steel. Additionally, standard paints turn brittle, fracturing upon minor forklift impact. Conversely, galvanized steel forms an intermetallic alloy bond that maintains ductile adhesion down to -50°C. The surface remains completely non-porous and naturally antibacterial, making it easy to wash down. Furthermore, galvanized racking features pre-engineered base drainage holes to evacuate condensed moisture before it freezes inside the hollow vertical uprights.

Yes. As an OEM and ODM manufacturer, our CNC roll-forming tooling can match any teardrop, slotted, or keyhole connector geometry, including European 50mm and 75mm pitch profiles, American teardrop patterns, or Australian 76.2mm spacing. During project design, we calibrate the connector tolerance clearance by +0.3mm to account for the physical zinc immersion build-up on hooks and safety lock ports, ensuring easy field assembly and secure beam engagement without jamming or binding.

To provide an engineered AutoCAD layout, 3D structural model, and finite element load calculation, our engineers require: (1) Architectural floor plan showing column grid spacing, building clear heights, fire suppression risers, dock door locations, and floor expansion joints; (2) Concrete slab specification (thickness, compressive strength, rebar depth, and maximum allowable point loads); (3) Pallet specifications (width, depth, overall height including cargo overhang, and gross weight); (4) Material handling equipment profile (forklift mast type, collapsed height, maximum lift height, turning radius, and aisle width clearances); and (5) Environmental parameters (ambient temperature, humidity, and local seismic acceleration coefficients per local building codes).

All upright frames and beams are shipped in knockdown (KD) configurations to maximize container space utilization. Upright columns are nested head-to-toe and secured with heavy-gauge steel banding and high-density timber dunnage. Beams are bundled with non-abrasive polymer spacers between connectors to prevent transit scratches. For sea freight to destinations such as Africa, Latin America, Southeast Asia, or Europe, open container ends are secured with moisture-absorbing desiccant sacks and sealed in poly-stretch film. This ensures a 40' HQ container achieves 25–27 metric tons of payload capacity, minimizing the landed freight cost per pallet position.

Guangzhou Heda Shelves Co., Ltd. operates under a certified ISO 9001:2015 quality management system (Certificate No. 18624Q00169R0M) valid through June 2027, and holds European CE Structural Steel Component Certification (No. 2435-CPR-8605159) confirming compliance with EN 1090-1 and EN 15512. In addition, our galvanized steel components undergo continuous quality inspections, including magnetic thickness testing (ISO 2178), cross-hatch adhesion testing, and neutral salt spray resistance evaluations (ASTM B117) exceeding 1,000 continuous hours without red rust development.

Every export shipment includes a 10-year structural warranty on galvanized structural integrity against atmospheric rust and weld failure under rated loads. Every shipment comes complete with matching part numbers, step-by-step CAD installation manuals, and video documentation. For major warehouse installations, we offer on-site supervision by senior structural engineers or provide real-time remote video guidance. Critical spare parts, including beam safety locks, floor anchor bolts, and column base protectors, are bundled with the original container packing list for immediate operational support.
