China Cold Storage Doors Suppliers | Insulated Factory Doors for Optimal Temperature Control
Products Description
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. Therefore, in addition to trying to improve the heat and steam insulation performance of the cold storage door and strengthening the sealing performance of the door, some other effective measures must be taken, such as installing air curtains, setting up door buckets, electric heating, and other measures.

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, with moderate door size and frequency of opening. With polyurethane foam forming inside, no cold bridge, and good insulation performance.
Heavy Rotary Shaft Door – Double / Single Opening
The rotary door is a hinged door, which can be single or double opened. When the moving position of the sliding door is not enough or the insulation effect is required to be high. The door frame can use a dedicated rotary shaft door aluminum alloy net frame, with superior sealing performance.
Standard Manual Sliding Door – Single / Double Opening
The manual sliding door has the high-strength aluminum alloy thickened guide rail, and shares a single track. It floats and sinks, making it easy to open and operate smoothly. The silent effect is good, the sealing effect is better, the insulation is good, and the service life is long.
Lightweight Manual Sliding Door
The size of the door body is moderate, the structure is simple, and the internal polyurethane is foam formed as a whole, with good sealing and thermal insulation; At the same time, it has a safety device for escaping danger in the warehouse, which is safe and practical; The characteristic is that the door body is relatively light. Applied in industries such as food, supermarkets, warehousing, pharmaceuticals, and retail.
Electric Single Sliding Door
Electric single sliding door, equipped with an electric control system on the basis of manual opening sliding door, independently developed and easy to install; easy to operate: One click self-learning (measuring door width); Simple structure: No need to connect other electrical components externally; High torque: DC brushless motor, no need for clutch worm gear; Powerful function: equipped with anti-pinch, delay switch, full range three-stage continuously variable speed.
Electric Double Sliding Door
Electric double sliding door, equipped with an electric control system on the basis of manual opening sliding door, independently developed and easy to install; easy to operate: One click self-learning (measuring door width); Simple structure: No need to connect other electrical components externally; High torque: DC brushless motor, no need for clutch worm gear; Powerful function: equipped with anti-pinch, delay switch, full range three-stage continuously variable speed.
Air-Conditioned Gas Regulating Door
The insulation of the door panel is made of polyurethane integral foam, and the door frame is made of all aluminum alloy. The track is made of aluminum alloy floating and sinking, making the opening and closing of the door panel more lightweight and flexible. The airtight strip adopts special high-quality sealing strips with high compression resistance, high elasticity, low temperature resistance, and corrosion resistance, which take the airtightness of the airtight door to a new level.
Anti-Collision Free Door
The door panel is made of 304 stainless steel panel and molded with polyurethane foam. Built in ABS observation window, ensuring the safety of personnel, transportation vehicles, and logistics in both directions. The flexible anti-collision board material effectively absorbs the impact force, prolongs the service life of the entire door body, and reduces the injury caused by accidental scratching of personnel passing through when the door body is opened and closed. After personnel or vehicles pass through, it automatically closes and the door leaf closes tightly. It can prevent the loss of cooling capacity and facilitate entry and exit.
Frequently Asked Questions
What is the core material used in cold storage insulated doors?
The core material used in cold storage insulated doors is polyurethane foam, which provides excellent thermal insulation performance. The surface is typically made of PPGI (color customizable) or stainless steel SUS304 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 for easy installation, with aluminum alloy profiles spliced on site. A fully buried swing door features the door body flush with the door frame, offering a more aesthetically pleasing appearance with enhanced sealing and insulation, and no cold bridge effect.
Can the size of the cold storage door be customized?
Yes, all cold storage insulated doors are available in customized sizes to meet the specific requirements of different cold storage facilities, processing workshops, and industrial applications.
What are the advantages of the electric sliding door over the manual sliding door?
The electric sliding door is equipped with an electric control system featuring one-click self-learning (door width measurement), a DC brushless motor with high torque, anti-pinch protection, delay switch, and three-stage continuously variable speed control — offering greater convenience, safety, and automation compared to manual sliding doors.
What industries are cold storage insulated doors suitable for?
Cold storage insulated doors are widely used across various industries including food processing, supermarkets, warehousing and logistics, pharmaceuticals, retail, low-temperature processing workshops, and any facility requiring temperature-controlled environments.
How does the anti-collision free door protect personnel and vehicles?
The anti-collision free door is constructed with a 304 stainless steel panel and polyurethane foam, featuring a built-in ABS observation window for two-way visibility. Its flexible anti-collision board absorbs impact forces effectively, reducing the risk of injury. After personnel or vehicles pass through, the door automatically closes tightly to prevent cooling capacity loss.
