CE Certified Freezer Pallet Racking Factories & Exporter

For sub-zero freezer environments operating between -20°C and -30°C, standard commercial carbon steel (such as standard Q235B or S235JR) is prone to temperature-induced embrittlement. Remprack recommends micro-alloyed low-temperature structural steel grades such as Q355D, Q355E, or European equivalent S355J2 / S355K2. These steel grades undergo Charpy V-Notch impact testing at -20°C to -40°C to ensure the structural material retains ductility, absorbing kinetic impacts from forklifts without catastrophic brittle fracture.

CE certification according to EN 15512 validates that the structural pallet racking system has undergone comprehensive limit state design verification. It accounts for sway stability, beam deflection limits (typically L/200), upright frame buckling resistance, beam-to-column connector rigidity, and dynamic safety factors. In cold storage facilities where frost accumulation and heavy pallet unit loads (+1,500 kg/pallet) present extreme risk, EN 15512 compliance guarantees structural reliability and regulatory compliance across European and international jurisdictions.

Both finishes offer distinct advantages depending on humidity levels:

1. Hot-Dip Galvanizing (ISO 1461): Ideal for severe humidity, blast freezers, and wet environments where ice thaw occurs frequently. The zinc coating provides sacrificial cathodic protection, ensuring complete immunity to rust even if scraped by pallets.

2. Thermosetting Epoxy-Polyester Powder Coating: Ideal for stable sub-zero environments (-25°C) with low moisture ingress. Remprack applies an automated multi-stage chemical wash, zinc phosphate pretreatment, and 80–100 micron electrostatic powder coat cured at 200°C to prevent micro-cracking and flaking.

While Drive-In racking provides high density, it requires forklift trucks to physically drive deep inside the structural rack lanes. In cold rooms, driving inside cold steel channels creates high risk of rack column damage, slows down pallet throughput, and increases operator fatigue. Radio Shuttle racking uses semi-automated self-propelled runners inside deep lanes. Forklifts remain safely at the face of the aisle, increasing handling speeds by up to 200%, minimizing rack collision hazards, and maximizing volume utilization up to 90%.

To engineer an accurate layout and structural proposal, please provide:

• Architectural warehouse drawing (CAD file or dimensioned PDF showing column grids, clear height under sprinklers/evaporators, and dock door locations).
• Pallet specification: Width × Depth × Height (including load) and maximum gross weight per pallet (kg).
• Operating temperature range (°C) and humidity conditions.
• Forklift truck model, maximum lift height, and minimum right-angle turning radius.
• Preferred inventory management protocol (FIFO vs. LIFO) and target SKU throughput.

When racking is installed at ambient room temperature (+20°C) and the facility is subsequently pulled down to operational temperature (-30°C), a temperature drop of 50°C causes steel contraction of ~0.6mm per meter. Across a 50-meter rack block, total contraction reaches 30mm. Remprack engineers incorporate specialized expansion joint gaps, slotted anchor holes, and flexible beam connectors to accommodate thermal movement without inducing destructive shear stress on floor anchors or frame diagonal bracing.

Yes, we cater extensively to system integrators, distributors, and OEMs worldwide. We offer custom powder coat matching (RAL color system), customized punch patterns (including US Teardrop, European 50mm pitch, and 75mm pitch profiles), custom load labels, OEM packaging, and branded engineering documentation.

Standard manufacturing lead time is 14 to 25 days depending on project volume. Components are tightly bundled, labeled, and wrapped in protective moisture-proof plastic film to prevent transit corrosion. Our export logistics team optimizes container loading (20GP / 40HQ) using specialized loading rigs to maximize steel tonnage per container, lowering international ocean freight costs for overseas buyers.
