The prefabricated cold storage, which is assembled on site, adopts lightweight composite materials such as the insulated metal sandwich panels as the thermal insulation envelope.

Usually, it is in the form of a single-story cold storage with a light steel structure that is able to be assembled into cold storage facilities of different dimensions and heights according to different sites. The product can be installed either outdoors or indoors, and can also be disassembled or transported. Thermal insulation sandwich panels are assembled and fixed with a special snap-in structure to ensure outstanding thermal insulation and air tightness of the cold storage.

Prefabricated cold storage can be divided into small indoor cold storage, inner structure cold storage and outer structure cold storage according to the relative position of the cold storage thermal insulation material and the main structure. Different types of cold storage have different requirements for structural steel.

Inner structure cold storage, also known as American-Style cold storage. The advantages of this product are stable structure after cooling, little structure maintenance workload, and easy installation of equipment such as refrigerator and lighting. However, the utilization of this product is low, and low-temperature-resistance is required, and it is difficult to realize air tightness and  water tightness of the roof.

Outer structure cold storage. The utilization rate of this product is high, the fire protection specifications such as firewall and fire partition are easy to achieve, and the building facade is not affected, but the external frame of the outer structure cold storage is greatly affected by the outdoor elements with heavy maintenance workload.

Small indoor cold storage refers to small indoor sites for refrigerating, processing and storing products. The space capacity can be changed according to the user’s needs with flexible disassembly feature, allowing for easy assembly and convenient transportation.
