How to choose the right cold storage panel?
1. Surface Material
PPGI steel: Cost-saving for fruit/vegetable storage, dry workshops.
304 stainless steel: Anti-corrosion for seafood plants, slaughterhouses & clean food workshops.
Custom anti-corrosion sheets available.
Steel gauge: 0.4–0.5mm for mini cold rooms; 0.6–0.7mm for busy logistics warehouses against forklift hits.
2. Panel Thickness by Temperature
100mm: 2~10℃ fruit & vegetable pre-cooling storage
150mm: 0~-18℃ meat freezer storage
200mm: -25~-60℃ ultra-low temp freezer, vaccine room & tropical-area cold storage
3. Insulation Standard
42kg/m³ PU foam density, thermal conductivity ≤0.024 W/(m·K). Lower value means less power consumption, perfect for hot regions.
4. Fire Rating
B1: Pharma warehouses, large food factories, EU & US projects with strict fire codes
B2: Small farm storage & simple cold rooms for basic fire safety
5. Surface Texture
Flat: Easy disinfection for pharmaceutical & clean workshops
Micro/wide ribbed: Strong, scratch-resistant for forklift-heavy logistics warehouses
Embossed: Decorative finish for small commercial cold rooms
6. Custom Sizes
Wall panel width: 400–1120mm; wider panels cut cold leakage at joints.
Max length 11.85m fits 40HQ containers; custom lengths reduce on-site assembly work.
7. Application Matching
Fruit/supermarket cold rooms: 50mm PPGI flat panel, B2 fire grade
Meat/seafood freezers: 100–150mm ribbed stainless panel, B1 fire grade
Pharma & ultra-low temp storage: 150–200mm high-density PU panel, B1 flame retardant
Food clean workshops: Stainless flat panel, anti-corrosion & easy cleaning
