Porta-King’s Modular Mezzanines transform unused vertical space into functional work or storage space. When building out becomes difficult or too costly, build up with modular mezzanines and platforms. These units are easy to install and have the added benefit of being reconfigured when floor plan changes deem necessary. Mezzanines are not really reconfigurable but they can be added onto as needs change.
