Polyurethane Sandwich Panel Thermal Insulated Cold Storage Freezer Room Sliding Door

Cold storage door refers to the door installed in cold storage equipment, refrigerated warehouse and other freezing environment equipment for insulation and sealing. The cold storage door adopts high-strength aluminum alloy door frame, which has high strength, no deformation, beautiful appearance and durability; The door leaf is surrounded by 2.0mm aluminum alloy, which is firm and durable, without deformation, and has reasonable structure. Generally, the door leaf of the cold storage door is injected with a polyurethane pressure injection machine for one-time foaming molding.
The polyurethane structure is dense and evenly fills all parts of the door without shrinkage. The door surface is flat and beautiful, with reliable thermal insulation performance. The internal guide rail of the cold storage door adopts the floating open and sinking closed door opening system. When the cold storage door is opened, the sealing strip reduces the friction of the cold storage aluminum alloy door frame. When it is closed, the cold storage door presses the aluminum alloy door frame according to the self weight of the door body to achieve the sealing effect. The door has high precision, beautiful and durable appearance, which ensures that the cold storage door is light and flexible, safe and labor-saving, and easy to install. TPE environmental protection sealing strip makes the cold storage door have better sealing performance and service performance.
Lingguan cold storage door type: manual single opening sliding door, manual double opening sliding door, electric single opening sliding door, electric double opening sliding door, semi buried door and full buried door.
