The rack mezzanine is a kind of rack which adopts the rack as a support and lays access floors, guard rails, pedestrian stairs, cargo chutes, freight elevators and hydraulic lift platforms to become a two storey or multi storey storage unit. It can save space and efficiently use the warehouse to improve utilization. In addition, at the top of the rack, the entire floor slab can be added to set up a steel platform, so as to form a goods placing pattern with lower rack and upper platform. Another rack can also be flexibly designed on the platform.
