Double depth shelving is a high-density storage system developed on the basis of crossbeam shelving, which focuses on improving space utilization and adapting to specific turnover needs Batch single item storage: suitable for industries such as food, beverages, and daily necessities with large quantities of single items and medium turnover frequency. By adopting a dual depth layout, the number of channels can be reduced and storage density can be increased. E-commerce and retail replenishment warehouse: used to store seasonal stock or best-selling items, optimizing warehouse space occupancy while ensuring certain access efficiency. Manufacturing raw material warehouse: For standardized packaging raw materials (such as plastic particles and metal profiles), centralized storage is achieved and specialized forklifts (such as telescopic forklifts) are used for storage and retrieval. Third party warehousing: In scenarios where the customer's goods category is relatively single and the inventory is large, balancing storage costs and turnover needs, and adapting to the model of multiple customers sharing warehousing resources.
