Products Description
Element manufactures Pu Panels for Cold Rooms using 0.5mm PPGI (Pre-Painted Galvanized Iron) sheets. Thicknesses from 50-250mm can be customized. Panel density is always 40-42 kg/m³. Standard widths are 1120 mm/1000/950 mm. Any RAL color is available upon request. The panel interface features Camlock (Tongue & Groove) with a built-in gasket for a tight, energy-efficient seal, ensuring quick and secure installation. Standard machine-made panels are also available.

How to produce the cold storage panel?
Dual-Sided Pre-Coated Metal Facings
Selected galvanized or color-coated steel (0.4-0.8mm) undergoes degreasing, dusting, and dual-sided anti-corrosion coating pretreatment.
Precise PU Raw Material Formulation
Polyol and isocyanate are mixed at a precise 1:1.05 ratio with eco-friendly blowing agents (e.g., cyclopentane), flame retardants, and catalysts.
Continuous High-Pressure Lamination & Foaming
Synchronized, aligned facings are injected with the mixture via high-pressure (150-200bar) foaming machines and pressed through dual conveyors (50-200mm adjustable spacing) at 40-60°C for curing.
Controlled Curing & Mandatory Performance Tests
Panels are cured for 24 hours at 20-25°C and 50-60% RH, then tested for core density (≥40kg/m³), thermal conductivity (≤0.024W/m·K), and compressive strength (≥200kPa).
Critical Performance & Dimensional Standards
Final product must achieve closed-cell content ≥95%, fire rating ≥B1 (GB8624), and tight dimensional tolerances (±2mm length/width, ±1mm thickness).
Precision CNC Cutting & Protective Packaging
Continuous slabs are precisely cut (±0.5mm) and trimmed by CNC, then packaged in moisture-proof PE film and palletized with a maximum stack height of 1.5m.

How to choose the cold storage panel thickness?
| Cold Room Type | Design Temperature Range | Recommended Panel Thickness | Application & Notes |
|---|---|---|---|
| Fresh Storage / Chilled Room | +10°C to -2°C | 100mm (Standard) / 120mm | Storage of fruits, vegetables, flowers, pharmaceuticals, dry goods. The most common and cost-effective thickness. |
| Low-Temp Freezer Room | -10°C to -18°C | 120mm (Market Standard) / 150mm | Long-term storage of frozen meat, ice cream, seafood. -18°C is the universal standard; 120mm is widely used. |
| Deep Freezer Room | -20°C to -30°C | 150mm (Standard) / 200mm | Blast freezing tunnels, tuna freezing, bio-sample storage, industrial low-temperature testing. Requires superior insulation. |
| Blast Freezer / Shock Freezer | -30°C and Below | 200mm or Thicker | Designed to rapidly lower the core temperature of products to -18°C or below within hours. Maximum thickness is essential. |
| Climate-Controlled Room / AC Room | +15°C to +25°C | 50mm / 75mm / 100mm | Cool storage, packaging areas with less stringent temperature requirements. Thickness depends on energy efficiency goals. |
