Warehouse racks are common storage equipment, and packaging, transport, loading/unloading, sortation, and information management are logistics' six basic functions. Racks use a three-dimensional structure to unlock warehouse space and lift capacity use. Watch a few points. First, cargo size and weight. Outer dimensions drive rack spec choice; cargo weight drives the strength grade. Before building, factor not only today's storage but two years of growth, and talk through details with actual users. Second, storage rate. Different racks store differently, driven by cargo spec, storage method, cargo weight, and warehouse height. At 4 meters or more of height, consider a rack-supported mezzanine — high storage rate and broad use; for heavy loads like steel plates, pick heavy-duty beam racks rather than forcing a mezzanine. Third, pairing with cages. When cages sit directly on rack beams, send us both the cage's outer dimensions and the beam spacing; we match the cage feet to the rack so it seats firmly.
