Generally, it is pre produced by the manufacturer and has a fixed length, width, and thickness. High and medium temperature cold storage generally use 10 centimeter thick plates, while low-temperature and frozen storage generally use 12 centimeter or 15 centimeter thick plates; So if it is not a pre ordered storage board, attention should be paid to the density of the storage board and the thickness of the steel plate when purchasing. The thickness of the steel plate from regular manufacturers is generally above 0.4mm, and the foam density of the cold storage board is 38KG~40KG/cubic meter according to national standards.
The polyurethane cold storage panel uses lightweight polyurethane as the inner material of the cold storage panel. The advantage of polyurethane is that it has excellent thermal insulation performance. The exterior of the polyurethane cold storage panel is composed of SII, PVC color steel plate, and stainless steel plate components. The advantage of doing this is to prevent the temperature spread of the cold storage panel due to the large temperature difference between the inside and outside, thereby making the cold storage more energy-efficient and improving the working efficiency of the cold storage.
