Cold Room Panel Surface Sheet Options: Color Steel, Galvanized, 304 & 316 Stainless Steel
Face sheet protects PU foam core from mechanical impact, moisture and corrosive gas; material selection matches cold room application environment. 0.4–0.5mm color coated steel plate: most cost-effective, smooth surface, easy cleaning, widely used for general frozen and fresh cold storage. Galvanized sheet: scratch resistance better than color steel, no paint layer; used for warehouse with frequent cargo collision, low corrosive environment. 304 stainless steel sheet: food grade, anti-rust, suitable for slaughterhouse, seafood workshop, high humidity food processing cold room. 316 stainless steel sheet: chloride resistant, selected for brine seafood cold room, frequent sanitizer washing and coastal salt spray environment. Xiteliduo cold room PU panel HS 940600 supports all four face sheet materials, thickness customizable from 0.4mm to 0.8mm. Color steel surface coating: polyester PE coating standard; HDP high durable coating for outdoor exposed cold room to resist UV aging. Stainless steel panel cost is obviously higher; only use where corrosion risk exists to control project budget. Hard sharp forklift operation easily scratches surface sheet; scratch breaks protective layer and becomes starting point of rust. Acid and chlorine disinfectant directly sprayed on stainless steel surface for long time will still cause pitting corrosion. Refrigeration maintenance & repair company touches scratch area regularly; touch-up paint for color steel, passivation treatment for stainless steel scratch.
