Work Platforms & Mezzanines

“Mezzanine” and “work platform” are synonymous. Both terms refer to the same system and will be used interchangeably throughout this page. These platforms are also known as lofts, standing platforms, storage platforms, and equipment platforms. 

On the other hand, mezzanines may be mistaken for mezzanine floors or balconies (as is commonly seen in concert halls and venues). Both of these serve as elevated functional spaces, but AK Material Handling Systems deals solely with warehouse mezzanines. 

Care must be taken in the terminology used in the permit application, as this could trigger sections of building code that are not necessary.

Types of Mezzanine Platforms

Freestanding Work Platforms

Freestanding work platforms are self-supported and can be placed anywhere within a warehouse. Four heavy-duty steel columns support the structure. Free standing mezzanines can move if needed.

Rack-Supported Mezzanines

Rack-supported work platforms are designed within existing pallet rack systems and directly above working aisles. The platform bolts to the upright columns and creates new storage space in a warehouse. 

Shelving-Supported Mezzanines

Like rack-supported mezzanines, shelving-supported mezzanines are secured to existing shelving for storage and handling space below and above the platform.

Building-Supported Mezzanines

Building-supported mezzanines attach to a building’s architectural framework – typically protruding from an outer wall. Like all work platforms, building-supported work platforms create additional floor space and facility flexibility. 

Catwalk Work Platforms

Generally, catwalks provide runway access from one elevated surface to another. They often serve as maintenance or inspection access.

Multi-Level Work Platforms

Some work platforms have two or even three unique levels. The number of vertical levels depends on building codes, capacity, ceiling height, and intended use.

When designing a warehouse mezzanine, there are many customization options. Businesses should choose each component based on the application at hand. Equipment platform customization options include:

• Framing: Mezzanine framing is the essential support structure that affects any work platform’s size and capacity limits. Framing options for mezzanines, from smallest to largest size and capacity, include bolted c-sections, beam & c-section, beam & beam, beam & bar joist, and truss girder & bar joist.
• Stairs: Common mezzanine stair customizations include stair orientation, number of landings, dimensions, and material (steel, aluminum, or other alloys). Additionally, warehouses must select the tread and riser design, proper non-slip surfaces, and handrails for application. Different stair types include welded, knockdown, and modular staircases.
• Access gates: Mezzanine access gates come in many styles. Standard gate styles include swing gates, slide gates, lift-out gates, tilt gates, impact gates, and pivot gates. More industrial mezzanine safety gates include pivot, double-drop, overhead, and pallet drop zone gates.
• Decking and flooring: Common mezzanine decking options include steel grating, resin board, plywood decking, bar grating, solid steel plates, open-deck, fiberglass grating, perforated steel decking, diamond plate, grated decking, full mat flooring, or combination decking.
• Lift type: When needed, mezzanine lifts include automated tote lifts, modular box lifts, hydraulic lifts, mechanical modular lifts, and Vertical Reciprocating Conveyors (VRC).
• Guardrail systems: Guardrails prevent deadly falls or falling items. Common guardrail options include standard guardrails, picket guardrails, mesh or wire mesh guardrails, toeboard extensions, kickplates, adjustable guardrails, collapsible guardrails, and more.
• Platform size: Platform size is determined by available warehouse space, storage, and capacity needs. The height, footprint, and capacity are all size factors to consider in a design.
• Capacity: Work platform capacity is influenced by the structural design, load distribution, column size, column material, column spacing, floor material and thickness, connection methods, and live vs. dead loads.
