Double your usable space without moving or building. A free-standing structural mezzanine adds a second level inside your existing walls — for storage, offices, assembly, or pick modules. Alliance designs, engineers, and installs mezzanines and work platforms nationwide, complete with stamped permit drawings, code-compliant stairs and guardrail, and turnkey installation.
Most warehouses are paying for cubic space they never use — the air above head height. A free-standing structural mezzanine reclaims it, adding a full second level for storage, offices, assembly, or carton-flow pick modules without expanding the building or disrupting the structure below. Alliance designs the column grid, beam-and-joist framing, decking, stairs, and guardrail around your loads and floor plan, produces stamped engineered drawings for permitting, and installs it turnkey — including pallet gates and lifts to move product between levels. It's typically a fraction of the cost of building out or relocating.
Structural steel columns on engineered base plates carry the platform load to the floor — free-standing from the building.
A beam-and-joist grid spans the columns to support the deck and the rated live load.
Bar grating, resin board, or steel deck surface — chosen for the load, traffic, and whether you need light to pass through.
Code-compliant stairs, guardrail, and toe-kick — plus pallet gates and lifts where you move product between levels.
The workhorse of warehouse storage — direct access to every pallet. Roll-formed (teardrop) and structural bolted styles for any capacity. Best all-around for mixed SKUs.
High-density storage where forklifts drive into the bay. Drive-in for LIFO, drive-thru for FIFO — maximize cube when you store many pallets of few SKUs.
Cart-and-rail systems storing 2–6 pallets deep per level with LIFO rotation — high density with far better selectivity than drive-in.
Gravity roller lanes for true FIFO rotation — load one side, pick the other. Ideal for high-throughput and date-sensitive product.
