Many types of industrial storage systems are built using pallet racks, like this rack supported mezzanine.
We designed this system with one access staircase, and one beam level below the bar grating floor.
Another industrial storage system built from pallet rack is a multi-level catwalk rack system, mostly used for order picking. Catwalk rack systems are also used in records storage rack applications, to hold large volumes of archive boxes.
