Stair systems from our world-wide suppliers!
Often the hardest wearing section of any building are stairways and various manufacturers have their own answer on how to solve the issue. The latest offering from Roppe includes the additional of Dupont’s Kevlar as an option.
We are still re-tooling the rubber templates for Australian compliance – but stay tuned!
If it is in a commercial application the critical thing to note is that there has to be a 30% contrast on the leading edge of each step within 5mm of the edge of each step. That means if the visual reference is set back by 15mm from the leading edge and has 30% contrast – it still will not be compliant with recent BCA regulations.
We recommend using American Biltrite Stair Systems that are designed and made in Canada to comply to Australian standards.

Before we consider heading into looking at our range,
let’s look at this topic and Australian requirements.
What is AS1428.1?
Courtesy of Safety Step we provide an overview on this topic.

This Safety Step post is a plain English examination and comment on how the Australian Standard AS 1428.1 impacts on the design and performance of .
The full title is Australian Standard Design for Access and Mobility Part 1: General requirements for access – new building work.
This Standard sets out minimum design requirements to provide access for most people with disabilities and addresses a wide range of building design elements.
Clause 11 of the Standard specifically addresses requirements for stairways and stair nosings and in this regard focuses almost entirely on promoting luminance contrast at the leading edge of step treads together with the avoidance of overhang at the front of stair treads.
Is AS1428.1 a mandatory requirement?
The actual Standard has no mandatory power, however the Building Code of Australia (BCA) adopts AS1428.1 and requires mandatory compliance with that Standard and is enforceable by law. Clause D3.3(a)(ii) of the BCA states that in any new development, and in major refurbishment all stairways (except a fire stairway) must comply with Clause 11 of AS1428.1.
What does AS1428.1 say about stair treads and stair nosings?
- Stair nosings are not allowed to project beyond the face of the riser.
- Stair nosings must be continuous across the full width of the stair tread.
- Stair nosing profiles may have a sharp intersection or a radius up to 5mm, or up to a 5mm x 5mm chamfer at the tread/riser intersection.
- A luminance contrast strip that provides a strong visual clue of the tread/riser intersection must be included.
- The strip needs a luminance contrast of at least 30% with respect to the background material.
- The luminance contrast strip must be between 50mm and 75mm wide and cannot be set back from the tread/riser
- intersection by more than 15mm.
- When located at the front of a stair nosing, the luminance contrast strip cannot extend down the riser more than 10mm.
- Stair risers must be opaque.
What is the definition of ‘stairway’?
To answer the question, ‘When is a stairway a stairway‘, two (or more) continuous steps would be considered a stairway and will trigger AS1428.1 requirements for TGSIs, handrails, and stair nosing.
Are all stairways included in AS1428.1?
What is “luminance contrast”?
Luminance contrast is defined in Standard 1428.1 as ‘the light reflected from one surface or component, compared to the light reflected from another surface or component’. It is not simply the difference in the colour contrast but the difference in the light reflective properties of each colour.
Luminance contrast is preferred to colour contrast as it highlights the difference in the light/dark qualities of two adjoining surfaces rather than just their colours”.
In practical terms, this is what it’s all about:
Below are examples of non AS 1428.1 compliant stairs, not achieving the required minimum 30% luminance contrast or minimum strip dimensions and also not meeting anti-slip requirements:
