1. Thickness requirements‌: Low-temperature cold storage usually uses thicker sandwich panels, generally 120mm or 150mm thick. This is because thicker panels can better isolate the outside temperature and maintain a low-temperature environment in the warehouse.

 

‌2. Material requirements‌: Cold storage panels should use composite insulation panels made of polyurethane foamed steel plates or stainless steel plates on both sides, with a thickness of at least 100mm. The insulation material should be flame-retardant and free of chlorofluorocarbons. A certain proportion of reinforcing materials can be added to improve performance, but the insulation effect cannot be reduced.

 

‌3. Density requirements‌: According to national standards, the foaming density of cold storage panels should be between 38KG and 40KG/cubic meter.

 

‌4. Protection requirements‌: The protective materials of cold storage panels can be embossed color steel plates, stainless steel plates, color zinc steel plates, etc. These materials have strong anti-rust and anti-corrosion capabilities and can adapt to low-temperature environments.
