Mezzanine shelving system is the creation of an intermediate loft over an existing work site or shelf to increase storage space. It can be made into a two- or three-story loft. Suitable for picking up some light foam and small and medium goods. The goods are usually sent to the second or third floor by forklifts, hydraulic lifting platforms or freight elevators, and then sent to a certain position by light vehicles or hydraulic pallet trucks. Suitable for high warehouses, small goods, manual access and large storage. Attic shelf floor designs are tailored to a variety of installation conditions and can be easily assembled on site without welding. Attic racking systems have many applications in auto parts, auto 4S stores, light industry, electronics and other industries.
