Product Description

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.

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
QWhat is the core material used in cold storage insulated doors?
The core material used in cold storage insulated doors is polyurethane foam. This material provides excellent thermal insulation, ensuring no cold bridge effect and maintaining stable temperatures within the cold storage facility.
QCan the size and surface material of the cold storage doors be customized?
Yes. Both the size and surface material are fully customizable. The standard surface is PPGI with customizable colors, and stainless steel SUS304 is also available with customizable thickness. Door dimensions can be tailored to fit your specific cold storage requirements.
QWhat is the difference between a semi-buried swing door and a fully buried swing door?
A semi-buried swing door uses a pre-factory integrated structure for easy installation, with the frame aluminum alloy profile spliced on-site. A fully buried swing door features a door body that is level with the door frame, offering a more aesthetically pleasing appearance and enhanced sealing and insulation performance.
QWhat are the advantages of the electric sliding door over the manual sliding door?
The electric sliding door is equipped with an independently developed electric control system that enables one-click self-learning for measuring door width, features a DC brushless motor with high torque, and includes anti-pinch protection, delay switch, and three-stage continuously variable speed control — making operation more convenient and efficient compared to manual sliding doors.
QWhat measures can be taken to prevent condensation and frost around cold storage door openings?
To prevent condensation, dripping, frost, and freezing around door openings, several measures can be taken in addition to improving the door's heat and steam insulation performance — including installing air curtains, setting up door bucks (door buckets), applying electric heating elements, and ensuring high-quality sealing strips are used around the door frame.
QWhat industries are cold storage insulated doors suitable for?
Cold storage insulated doors are widely applicable across a range of industries, including food processing and storage, supermarkets, pharmaceutical warehousing, retail, low-temperature processing workshops, and any facility requiring controlled temperature environments and efficient insulation solutions.
