Rubber Stairs

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?

Yes.

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:

FAQs

Absolutely not. The body of the stair nosing can extend any distance down the riser. If the luminance contrast strip is located at the front of the stair nosing then that strip cannot extend down the riser more than 10mm. This limitation is to avoid confusing the location of the leading edge of the tread. The body of the stair nosing, so long as it is clearly differentiated from the luminance contrast strip, can extend to any depth on the riser, like this:

The AS 1428.1 Standard prefers the strip to be one unbroken width, between 50mm and 75mm wide to maximise the contrast effect, however minor interruption to that strip is tolerated provided that the interruption does not adversely effect the luminance contrast effect. As an example, a 50mm strip may be presented as two 25mm strips with a very thin division between but not presented as five 10mm strips with bold divisions between.

Finally-4

A stair nosing is permitted to fold tightly down the front of the stair riser after forming a sharp intersection at the tread/riser intersection, but the stair nosing should not extend outward or form an overhang at the front of the tread.

Yes it can so long as the glow feature is located correctly within the nosing. To remain compliant with AS1428.1 the luminous contrast strip cannot be situated further than 15mm back from the front edge of the tread so any glow feature should sit either immediately in front of or immediately behind the contrast strip while retaining the contrast strip width between 50mm and 75mm.
