Based on the polyurethane that has good thermal insulationproperties has the inner material of cold storage panels,the interlayerstyle pane! made by the pattrn-steel panels is adopted outsideIt canreduce transfer of heat caused by the dfferent temperature differencesinside and outside for the maximum fficiency in the freezingsystem.The adhesion between the pattrn-steel in 4mm and PU canomit the bearings of the civil engineering and the isolating air and dampproof course. It can also bear the Forklift running on the pastern-steelpanels.The optional thickness and specification:100120,150. 180,200and 250mm
