Cold Storage Sandwich Wall Ceiling Panels

Cold storage sandwich panel for cold storage and cold room

Cold Storage Sandwich Wall & Ceiling Panels（100-200mm）

Through prestaging the special airtight rubber in wedge-shaped structure between internal and external layer of PNS Brand cold storage panel, so that the adjacent panel of the inner and outer layers of cold steel as one organic,greatly overcome the thermal expansion and contraction phenomenon of cold storage panel,make the whole air tightness performance is equivalent to the effect of seamless steel plate welding.
