Multi-level, or multi-tier storage shelving structures, are comprised of either Metalware Interlok “No-Bolt” shelf units or E-Series Widespan shelving. These types of systems can be referred to as “catwalk” or “deck-over” shelving mezzanines.  Both Interlok and E-Series Widespan offer significant upward expansion thanks to the possibility of being transformed into multi-level storage applications, allowing our clients to maximize their storage capacities while minimizing costs linked to relocation or warehouse expansion.

Our in-house design and engineering staff will provide custom designs to meet your current and future needs.  Customizations include factory-made stairs, handrails, grating, pivot and safety gates, and other accessories for ventilation, lighting, and sprinkler requirements.
