Mezzanine stairs are purpose-built steel staircases that provide safe, compliant access between a ground floor and a raised mezzanine level. Advantage Industries manufactures prefabricated mezzanine stairs in Australia for warehouses, factories, retail fit-outs, and residential mezzanine floors — designed to meet NCC/BCA requirements, shipped flat-packed Australia-wide, and built to handle heavy daily use.
With over 35 years of manufacturing experience and 10,000+ staircases installed, we supply three distinct mezzanine stair solutions to match your space, budget, and load requirements: EasyStair for heavy-duty industrial use, EcoStair for residential mezzanines and sheds, and Custom Industrial Staircases engineered for complex installations.
What Are Mezzanine Stairs?
A mezzanine stair is the staircase that connects your ground floor to a mezzanine — an intermediate floor built between two main storeys, usually used to create extra storage, office space, or retail area without expanding the building footprint. Because mezzanines are permanent structural additions, the stairs that access them must meet the same Australian building code requirements as any other staircase in the building, including AS 1657 for industrial access and the NCC (National Construction Code) for commercial and residential applications.
Our mezzanine stairs are fully prefabricated in Queanbeyan, NSW. Each kit arrives on site bolt-together or weld-together, with all treads, stringers, handrails, and fixings pre-cut and powder-coated. A standard two-person crew can install an EcoStair mezzanine kit in under a day; larger industrial mezzanine staircases typically take 1–2 days depending on site access.
Our Mezzanine Stair Range
EasyStair — Heavy-Duty Industrial Mezzanine Stairs
EasyStair is our flagship industrial mezzanine stair kit. Welded steel stringer construction, full checker-plate treads, and 2-pipe or 3-pipe handrail options. Designed for warehouses, factories, and commercial mezzanines where the stairs will handle daily foot traffic, trolleys, and point loads.
- Load rating: 5 kPa uniformly distributed live load (AS 1657 compliant)
- Tread material: 5mm checker plate or open grating
- Heights: 2.4m to 4.5m standard, custom to 6m+
- Hot-dip galvanised or powder-coated finish
- Landing platforms and half-landings available
- Ships flat-packed, assembles on site
EcoStair — Residential Mezzanine and Shed Stairs
EcoStair is our affordable bolt-together mezzanine staircase, designed for residential mezzanines, shed lofts, and light commercial applications where budget matters and loads are lighter. Easier DIY assembly, still manufactured to last.
- Load rating: residential and light commercial
- Tread material: powder-coated checker plate
- Heights: 2.4m to 3.6m
- Bolt-together construction — no welding required
- Flat-pack delivery Australia-wide
- Starting from a fraction of the price of a custom welded staircase
Custom Industrial Mezzanine Staircases
When your mezzanine doesn’t fit a standard kit — unusual heights, heavy point loads, complex layouts, or integration with existing structural steel — our custom industrial staircase service builds to your engineered drawings. Full fabrication in-house at our Queanbeyan factory.
Common Applications
- Warehouse mezzanine stairs — access to pick-and-pack platforms, storage mezzanines, and racking structures
- Factory mezzanine stairs — access to production platforms, control rooms, and plant decks
- Retail mezzanine stairs — customer-facing access to showroom upper levels (powder-coat finish, open risers on request)
- Shed mezzanine stairs — loft access in domestic and rural sheds
- Office mezzanine stairs — internal access between mezzanine offices and the floor below
- Residential mezzanine stairs — home lofts, studios, and garage mezzanines
Australian Building Code Compliance
Mezzanine stairs in commercial and industrial settings must comply with AS 1657 — Fixed platforms, walkways, stairways and ladders. Residential mezzanine stairs fall under the NCC/BCA (National Construction Code / Building Code of Australia) Volume Two. Key compliance points:
- Stair angle: 30°–38° for normal mezzanine use; up to 45° for restricted industrial access
- Tread depth (going): 240mm minimum for commercial/industrial
- Riser height: 190mm maximum for commercial; 225mm for industrial
- Handrail height: 900mm minimum above nosing line
- Load rating: 5 kPa uniformly distributed or 1.1 kN concentrated for standard industrial use
- Headroom clearance: 2,000mm minimum
All Advantage Industries mezzanine stairs are manufactured to these specifications as standard. We supply engineering certification on request for certifier sign-off.
How to Choose the Right Mezzanine Stairs
Four questions determine which mezzanine stair solution fits your project:
- What’s the floor-to-floor height? Measure from finished ground floor to the top of the mezzanine. We build standard kits from 2.4m to 4.5m; custom to 6m+.
- What loads will the stairs carry? Foot traffic only? Trolleys and hand trucks? Heavy tools? This determines tread type (checker plate vs grating) and stringer thickness.
- How much floor space do you have? A straight-flight stair at 35° needs a run roughly 1.4× the rise. If floor space is tight, a half-turn (switchback) layout with a landing saves space.
- Who’ll be using them? Industrial staff only? Public/customer access changes the finish, riser type (closed vs open), and compliance requirements.

Mezzanine Stairs — Frequently Asked Questions
How much do mezzanine stairs cost in Australia?
Residential and shed mezzanine stair kits (EcoStair) start from around $2,000 + GST for a standard 2.7m rise. Industrial mezzanine stairs (EasyStair) typically range from $4,500 to $9,000 + GST depending on rise, tread type, and handrail configuration. Custom industrial staircases are quoted individually. Freight is additional and calculated by postcode.
Do mezzanine stairs need council approval?
Most mezzanine installations require building approval because the mezzanine itself is a structural addition. The stairs must be certified as compliant with AS 1657 (industrial) or the NCC/BCA (residential/commercial). We supply engineering documentation to support your certifier’s sign-off.
Can I install mezzanine stairs myself?
Our EcoStair residential kits are designed for DIY installation — two people, a drill, and a day. EasyStair industrial kits are also bolt-together but benefit from an experienced installer on larger rises. Custom industrial staircases are generally installed by a qualified fabricator or structural steel contractor.
What’s the difference between a mezzanine stair and a regular staircase?
The functional components are the same — treads, stringers, risers, handrails. What sets mezzanine stairs apart is the use case: they access a mezzanine floor, which means the stair has to comply with the mezzanine’s classification (industrial AS 1657 or NCC residential/commercial) and handle the loads typical of that use. Industrial mezzanine stairs are almost always steel for fire rating and durability; residential mezzanine stairs can be steel, timber, or hybrid.
What’s the minimum floor space needed for a mezzanine staircase?
A straight-flight mezzanine stair at 35° needs a horizontal run of approximately 1.4× the rise. For a 2.7m mezzanine, that’s roughly 3.8m of floor run plus 1m of landing. Tight on space? A half-turn (switchback) layout with a 1m × 1m landing cuts the footprint by roughly half.
How long does it take to get mezzanine stairs made and delivered?
EcoStair kits: 1–2 weeks from order. EasyStair industrial kits: 2–4 weeks. Custom industrial staircases: 4–8 weeks depending on complexity. Freight adds 2–7 days depending on destination. Urgent? We can expedite standard kits — just ask when you quote.
