Shelving/rack supported mezzanines or catwalks systems are designed for high density storage. They are very cost effective combining the storage and  the structural into one unit.

In Rack Supported Mezzanines, Storage Racks support a mezzanine floor with an open deck. The space you can reclaim with this high-density storage method is tremendous. Plus, you can utilize the rack for its normal storage purposes.

Rack supported mezzanines can even be used to build multi-tier storage, in certain cases. These involve rack at full height with walkways suspended across or on a deck above the aisles.
