1. Essential Materials for Cold Rooms
A. Insulation Core
PU Sandwich Panels (0.022W/(m·K)): For -40℃~+15℃
XPS Boards: High compressive strength (floors)
Rock Wool: Fireproof (Class A)
B. Surface Materials
Color Steel (0.4-0.6mm): Cost-effective (>0℃)
Stainless Steel (304/316L): Corrosion-resistant
Food-Grade PE Coating: Anti-microbial
C. Sealing
PU Foam Sealant: Gap filling
Low-Temp Silicone (Elastic at -40℃)
D. Flooring
XPS + Concrete + Anti-Slip Coating (Heated layer for <-18℃)

3.Key Differences:
A. High-Temp: Thinner insulation (100mm) + cost-effective panels
B. Low-Temp: Thicker insulation (150mm+) + stainless steel
C. Pharma: GMP-compliant, airtight seams
4.Pro Tip:
For seafood storage, 316L stainless steel resists salt corrosion.
XPS floors must withstand ≥300kg/m² load in logistics cold rooms.
