Cold storage panels are primarily composed of panels, insulation, moisture-proof layer, and reinforcing ribs. The panels are commonly made of materials like stainless steel and color steel plates, offering corrosion resistance and easy cleaning; the insulation is typically made of high-efficiency materials like polyurethane, providing excellent thermal insulation properties; the moisture-proof layer effectively prevents moisture inside the cold storage from eroding the insulation, thereby extending the service life of the cold storage panels.
