The difference between the cold storage insulated door and ordinary doors is that it needs to be insulated, because the cold storage insulated door is actually equivalent to an insulating structure that can be movable opened and closed, and is the only way for goods to enter and exit the warehouse.
The design and management of the cold storage insulation door is directly related to the service life of the entire cold storage. Due to the entry and exit of goods, the cold storage insulation door is opened frequently. When the storage door is opened, the hot and cold air inside and outside the storage is cooled and heated near the door opening. In exchange, the walls, floors, ceilings, etc. around the door opening are prone to condensation, dripping, frost, freezing and other phenomena. Effective measures must be taken, such as installing air curtains, setting up door buckets, and electric heating.
Core: Polyurethane Foam
Standard Surface: PPGI (Color Customizable)
Stainless Steel SUS304 (Thickness Customizable)
Size: Fully Customized
Semi-Buried Swing Door – Single / Double Opening
The semi buried door adopts a pre factory integrated finished product structure, which is easy and convenient to install and meets all the technical requirements of cold storage doors. The frame aluminum alloy profile is spliced and connected to the frame board on site, making it easy to install.
Fully Buried Swing Door
Fully buried door, characterized by the door body being level with the door frame, beautiful appearance, good sealing and insulation. Suitable for cold storage, low-temperature processing workshops, insulation devices. Polyurethane foam forming inside ensure no cold bridge.
Heavy Rotary Shaft Door – Double / Single Opening
The rotary door is a hinged door, which can be single or double opened. Ideal for situations where moving position of sliding door is insufficient or high insulation is required. The frame uses dedicated aluminum alloy for superior sealing.

Anti-Collision Free Door
Made of 304 stainless steel with molded polyurethane foam. Built-in ABS observation window and flexible anti-collision boards effectively absorb impact and protect personnel and vehicles.
What is the core material used in cold storage insulated doors?
All cold storage insulated doors use polyurethane foam as the core material. This ensures excellent thermal insulation performance, no cold bridge, and long-lasting energy efficiency for cold storage environments.
Can the door size and surface material be customized?
Yes. Door sizes are fully customizable to fit your specific cold storage requirements. The standard surface material is PPGI with customizable colors, and stainless steel SUS304 is also available with customizable thickness.
What is the difference between a semi-buried and a fully buried swing door?
A semi-buried swing door uses a pre-factory integrated structure with an aluminum alloy frame spliced on site, making installation easy. A fully buried swing door has the door body flush with the door frame, offering a more aesthetically pleasing appearance and enhanced sealing performance.
What are the advantages of electric sliding doors?
Electric sliding doors include a built-in DC brushless motor with one-click self-learning, anti-pinch protection, and three-stage continuously variable speed control. They are more convenient and safer for high-frequency operation environments compared to manual doors.
Which door type is recommended for forklift traffic?
The Anti-Collision Free Door is specifically designed for environments with frequent vehicle traffic. It features a stainless steel panel, observation window, and flexible anti-collision board that absorbs impact and automatically closes after passage.
What industries use these insulated doors?
These doors are widely used in food processing, supermarkets, pharmaceutical storage, warehousing, logistics, and controlled atmosphere (CA) storage facilities.
