When your warehouse runs out of floor space, you have two options: build new square footage or look up. An industrial mezzanine system creates a new floor level within your existing building, effectively doubling your usable space at a fraction of the cost of traditional construction.

Most mezzanines pay for themselves within 12–18 months when compared to the ongoing cost of leasing additional space. Here’s everything you need to know about specifying, installing, and getting the most from a mezzanine system.

What Is an Industrial Mezzanine?

A mezzanine is a freestanding elevated platform built inside an existing building. Unlike building additions, mezzanines don’t require foundations, exterior walls, or roofing. They’re classified as equipment (not permanent construction) in many jurisdictions, which simplifies permitting and may offer tax advantages through accelerated depreciation.

Types of Mezzanine Systems

Structural Steel Mezzanines

Built from hot-rolled steel beams and columns, structural mezzanines handle heavy loads (250+ PSF) and large spans. They’re the standard for manufacturing, heavy warehouse storage, and multi-level offices inside industrial buildings.

Roll-Form (Bar Joist) Mezzanines

Lighter-duty systems using cold-formed steel joists. Ideal for light storage, offices, and retail stockrooms where loads are under 150 PSF. Lower cost than structural but limited in span and capacity.

Rack-Supported Mezzanines

A platform built on top of pallet rack. This hybrid solution combines ground-level pallet storage with an upper-level work or storage area. Great for order picking operations and small-parts storage above bulk pallets.

Custom Catwalk Systems

Elevated walkways for overhead access to equipment, piping, HVAC, or storage. Custom catwalks are engineered for specific facilities and can include stairs, ladders, gates, and safety rails.

Mezzanine vs. Building Expansion

Factor	Mezzanine	Building Expansion
Cost per sq ft	$20–$60	$100–$250
Timeline	4–8 weeks	6–18 months
Permits	Building permit	Full construction permits
Disruption	Minimal (installed while operating)	Major (construction site)
Tax treatment	Often accelerated depreciation	Real property (27.5+ year)
Relocatable	Yes (bolted connections)	No

Load Ratings & Engineering

Mezzanine load ratings are measured in PSF (pounds per square foot) and must account for:

• Live load: People, stored materials, equipment, forklifts
• Dead load: The mezzanine structure itself, decking, and fixtures
• Seismic load: Required in seismic zones (all of Utah and much of the Western US)
• Impact load: Additional factor if forklifts operate on the mezzanine

Common load ratings: 125 PSF (light storage), 150 PSF (standard), 250 PSF (heavy storage), 300+ PSF (manufacturing). All our mezzanines include PE-stamped engineered drawings.

Frequently Asked Questions

Do mezzanines require a building permit?

Yes, in virtually all jurisdictions. The good news is that mezzanine permits are simpler than new construction permits. We provide PE-stamped drawings and handle the permitting process as part of every project.

How long does a mezzanine take to install?

Most mezzanines install in 1–3 weeks depending on size and complexity. Installation can happen during normal business hours without disrupting operations on the ground level.

Can I put an office on a mezzanine?

Absolutely. In-plant offices on mezzanines are one of the most popular configurations. We add fire-rated walls, HVAC, electrical, and modular panels to create comfortable office space overlooking the warehouse floor.
