Rack Supported Mezzanine Systems

Transform your unused vertical space into valuable operational square footage. Our Rack Supported Mezzanine Systems utilize heavy-duty pallet racking to create sturdy, multi level warehouse platforms for storage, offices, or order picking areas. This engineering solution is designed to maximize density and provide a highly cost-effective way to expand your facility without costly construction.

Overview of Rack Supported Mezzanines

A rack supported mezzanine uses the upright frames and beams of a new or existing pallet racking system as the primary support structure for an elevated floor. This creates a structural, mezzanine storage system that effectively doubles (or triples) the usable area within your existing facility footprint. This approach is highly efficient because the racking serves a dual purpose: storage and structural support. It requires precise engineering to meet strict deflection, seismic, and building code requirements.

What You Get in Mezzanine Storage

Our mezzanine solutions are complete, engineered packages that cover the structural, access, and safety components:

Heavy-Duty Racking Structure

The primary rack uprights and beams designed for increased vertical and lateral loads from the platform.

Structural Decking

High-strength flooring (e.g., steel deck, planking, or bar grating) that forms the usable upper level.

Stairs and Handrails

Code-compliant staircases, landings, and industrial handrails for safe and easy access to the industrial mezzanine platform.

Gate Systems

Safety gates (swing or sliding) and pallet drop zones to safely transfer product to the upper level.

Building Permits

Full coordination and acquisition of necessary permits, as mezzanines are considered structural alterations.

Lighting and Utilities

Integration of lighting, conduit, and electrical systems into the new elevated structure.

Fire Safety Clearance

Consultation to ensure the structure meets fire code requirements for smoke detection and sprinkler coverage.

Benefits of Multi Level Warehouse Platforms

Installing a mezzanine rack system offers immediate and lasting benefits to facility operations and space utilization.

Cost-Effective Expansion

Dramatically increases usable square footage without the high costs, permits, and time associated with conventional building construction.

Immediate Space Utilization

Quickly adds space for offices, break rooms, small parts storage, or supervisory workstations above existing operations.

Maximized Vertical Cube

Optimally utilizes the high ceilings common in modern warehouses, turning air space into productive floor area.

Design Flexibility

The structure can be customized to work around columns, equipment, and active work zones below.

Easy Relocation/Modification

Rack-supported mezzanines are often easier to disassemble, modify, or relocate than conventional steel structures, offering long-term flexibility.

Related Warehouse Systems

Mezzanines often work in conjunction with other dense or vertical storage systems to maximize facility efficiency.

Boltless Shelving

Ideal for installation on the mezzanine level for organizing small parts, cartons, or supplies.

Shelving-Supported Catwalks

A specialized multi-level picking system where shelving itself acts as the support, commonly used within mezzanines.

Single Selective Racks

Often installed beneath the mezzanine structure for bulk storage and easy access to pallets.

Warehouse Permitting

Essential service, as rack supported mezzanine systems are considered major structural changes requiring extensive permitting.

Frequently Asked Questions

Does Racforce handle the permitting process for the mezzanine?2025-12-16T07:34:26+00:00
Yes. Given the complexity of structural permits, seismic calculations, and fire code sign-offs, we provide complete permit management services for all multi level warehouse platforms we design and install.
How does a rack supported mezzanine differ from a traditional structural steel mezzanine?2025-12-16T07:33:24+00:00
A structural steel mezzanine uses heavy columns and beams independently. A rack supported mezzanine uses standard pallet racking components as its core support, making it more cost-effective and easier to integrate into existing racking operations.
Can I use the upper level for office space or heavy machinery?2025-12-16T07:28:34+00:00
The mezzanine must be designed and engineered for the intended load. We calculate the structure for light storage, office load (typically 50 PSF), or heavy machinery, ensuring the design meets the specified use.
What is the maximum height a rack supported mezzanine can be built?2025-12-16T07:27:56+00:00
The maximum height is determined by your building's ceiling height, local zoning codes, and the required clear height needed underneath the structure for forklift operations or traffic.
Does a mezzanine installation impact my fire code requirements?2025-12-16T07:27:12+00:00
Absolutely. Adding a floor changes smoke and heat dissipation, often requiring specialized fire suppression underneath the mezzanine, updated sprinkler calculations, and new egress planning. Fire consultation is critical.
Is a Rack Supported Mezzanine considered a permanent structural addition?2025-12-16T07:26:27+00:00
Yes. A mezzanine storage system is considered a structural component and requires full permitting and adherence to all building and seismic codes, just like a building addition.
