Industrial mezzanines.
Double your usable floor area without breaking ground. Free-standing structural mezzanines designed, P.Eng stamped, and installed by the same salaried crew that builds your rack.
A second floor, no foundation work.
An industrial mezzanine is a free-standing, fully engineered steel platform that sits on its own column grid above your existing slab. It adds usable square footage — for storage, picking, light assembly, or office — without altering the building envelope.
416 designs mezzanines as a bundled add-on to rack installs. One crew, one P.Eng, one project manager. Stair systems, perimeter gates, and decking ship and install on the same schedule.
Mezzanines are not a separate trade for us. They are an extension of the racking system that lives underneath.

Three typical bundles.
Adds capacity above pick aisles
Mounted above selective rack to double pallet positions. Wide-span design keeps the rack underneath fully accessible. Common in 3PL + e-commerce fulfillment.
Multi-level pick fronts
Integrated mezzanine + pick-shelf rack with conveyor cut-outs. Built for SKU-heavy distribution and case-pick operations.
Elevated office or service deck
Open floor below for forklifts + equipment. Office, lunchroom, or mechanical platform above. Permit-stamped, fire-rated when required.
Designed + installed right.
P.Eng stamped drawings
Every mezzanine ships with a sealed structural drawing set — column loads, footing loads, deflection check, seismic + live-load combos per OBC. Municipal permit packages handled by 416.
Code-compliant guardrails + gates
42" guardrails with 4" mid-rail and 4" toe-board per OBC. Pivot gates, slide gates, or self-closing swing gates at every loading edge.
Same salaried crew
Mezzanine install crews are the same people who build the rack underneath. No sub-contracted day-rate labour. Anchor torque-tested. Plumb + level checked before turnover.
Slab + footing verified
Mezzanine column point-loads cross-checked against your slab thickness + sub-base. If footings are required, 416 coordinates with the GC. Nothing gets anchored to an under-spec slab.
Stairs, gates, flooring.
Stair Systems
OBC-compliant industrial stairs — straight runs, switchback, and ship's-ladder configurations. Bolted to mezzanine frame, anchored to slab.
