Shelving Description: Smooth-flow racks, also known as self-slide racks, are constructed with roller aluminum alloy and metal strips. They utilize the weight of the goods shelves to achieve first-in, first-out (FIFO) storage, making inventory convenient and allowing for one-time restocking and multiple retrievals. These racks offer high storage efficiency, ideal for short-term storage and selection of large quantities of goods. Compatible with electronic labels for easy management, commonly used sliding containers include周转箱 (trolleys), parts boxes, and cardboard boxes, suitable for large volumes and short-term storage and selection. Widely used in distribution centers, assembly workshops, and warehouses with high shipping frequency.
