Which is more suitable for cold storage, through-type racks or gravity racks?

Choosing the right cold storage rack system in a cold storage environment is of vital importance. It is necessary to take into account both storage efficiency and energy conservation as well as operational convenience. Which is more suitable for cold storage, through-type racks or gravity racks? Let's find out below.

Drive-in racking, also known as through-type racking, is a design that uses forklifts to directly enter the racking aisles for operation, reducing the number of aisles. The storage density is 30% to 50% higher than that of ordinary beam-type racking. It is particularly suitable for the storage of large quantities of goods of the same category. Gravity shelves achieve the automatic flow of goods based on their own weight, allowing for the first-in, first-out principle. They are suitable for goods that are sensitive to their expiration dates. The goods slide automatically to the picking end, reducing the labor intensity of personnel.

It can be seen that through-type rack require forklifts to enter the aisles to store and retrieve goods, which is relatively inefficient. Gravity racking, on the other hand, works by allowing goods to slide down automatically. Forklifts can pick up goods at both ends of the aisle, and its efficiency is higher than that of through-type racking. In the cold storage environment, gravity shelves can significantly reduce the time personnel stay and lower energy consumption. Its smooth flow of goods also reduces the opening time, which helps maintain the stability of the low-temperature environment.
