Mezzanines & Structural Steel

Also called: steel mezzanine floor, structural platform

250–1,000 kg/m² · spans to 8 m · single, double or triple level

Its own columns and beams, independent of the racking. Change the storage underneath any time without touching the floor above.

Also called: rack-clad mezzanine, racking-supported floor

Upper floor carried on the pallet racking below

Less steel and less floor obstruction, at the cost of locking the rack layout in. Uprights must be designed for the combined load from day one.

Also called: shelving-supported floor, multi-tier floor

2–3 levels carried on the shelving itself

The economical route for hand-picked stock. Effectively the multi-tier racking system with a full walking floor.

Also called: process platform, plant platform

Point-load designed to the equipment schedule

Access and maintenance platforms around plant, tanks or lines. Designed from the machine's loads, not a uniform kg/m².

Also called: mezzanine loading gate, goods transfer level

Pallet gate, lift shaft opening or conveyor break

How stock gets up there is the part most often left until last. It determines throughput of the whole floor.

12–25 mm · commonly on a steel tray

The most common and least expensive deck. Cuts to a non-standard bay on site. Not for wet areas.

Also called: chequer plate, tread plate

3–6 mm · anti-slip pattern

Hard-wearing, non-combustible, takes point loads and trolley wheels without dishing. Heavier and noisier underfoot.

Also called: open grating, walkway grating

Open grid · load-bar depth to span

Lets light, air and sprinkler water through. Standard on process platforms and wherever the level below must stay visible.

Also called: mesh deck, wire deck

Mesh panel on channel supports

The in-rack sprinkler answer, and the deck that lets a fork driver see the beam being landed on.

2 mm mild steel panel per bay

For dense, small, heavy loads that would dish a ply sheet over a season — fasteners, boxed parts, tooling.

Also called: fibre cement deck, calcium silicate board

Non-combustible board over steel deck

Where a fire rating is required on the floor construction itself.

Also called: mezzanine staircase, access stairs

Straight, dog-leg or spiral · with handrail and kick plate

Rise, going and headroom follow the building code, not the space left over. Retrofitting a compliant stair later is expensive.

Also called: edge protection, balustrade

Typically 1,100 mm high · mid-rail and toe board

Continuous around every open edge. The toe board is what stops a dropped carton reaching the floor below.

Also called: pallet safety gate, up-and-over gate

Up-and-over or sliding · always one side closed

Lets a pallet be landed on the mezzanine with the operator never exposed to the open edge. The single most important item on a mezzanine's safety list.

Also called: swing gate, ladder gate

Spring-return · at stair and ladder heads

Removes the gap a chain leaves.

Also called: vertical ladder, hoop ladder

With safety hoops above 2 m

Maintenance access where a stair will not fit.

Also called: crossover, access gantry

Grating or plate on a light frame

Connecting levels, crossing conveyors, reaching plant.

Stepped bridge with handrails

Stops the habit of climbing over a running conveyor, which is how most conveyor injuries happen.

Also called: site office, portable cabin, prefab office

Insulated panel walls · glazed · wired

Supervisor offices, QC rooms and dispatch offices placed on the warehouse floor or on the mezzanine above it.

1–3 person · glazed on the gate side

Gate and weighbridge posts.

Also called: mesh partitioning, security cage

Floor-to-ceiling mesh with hinged or sliding door

Segregates high-value, controlled or bonded stock while keeping it visible and sprinkler-covered.

Mesh or panel enclosure with issue counter

Controlled issue of tooling and consumables against a signature or a scan.

Also called: perimeter guarding, robot cell fence

Mesh panels with interlocked gates

Around automation, palletisers and robot cells. Interlocks are the compliance item.

Panel walls, controlled entry, filtered air

Pharma and electronics assembly zones inside a general warehouse.

Also called: bespoke fabrication, job work

Cut, formed, welded and finished to drawing

Frames, stands, brackets, jigs, guards and one-off structures that no catalog line covers.
