Application.This section covers all stairways (including standard, spiral, ship, and alternating tread-type stairs), except for articulated stairs (stairs that change pitch due to change in height at the point of attachment) such as those serving floating roof tanks, stairs on scaffolds, stairs designed into machines or equipment, and stairs on self-propelled motorized equipment. The radius of curvature at the leading edge of the tread shall be no greater than 1/2 in (13 mm). Additional benefits are gained if the stair nosing is of a contrasting color to the rest of the stair tread. Can an AS1428.1 nosing also contain a glow in the dark feature? COLOR: Available in all 20 Uni-Colors. Three- and four-inch nosing widths are standard since 3-inch or larger nosings will satisfy the requirements of virtually all codes and standards. The leading edge of exit stair landings shall be marked with a solid and continuous marking stripe consistent with the dimensional requirements for stair treads and shall be the same lengths, and consistent with, the stripes on the steps. Quantum Stair Nosings. One of the best and most cost effective ways to increase visibility is by providing a visual contrast on the leading edge of treads. As a slip resistant stair part fitted onto the nose of each step, they help to clearly define the steps on a stair when a contrasting colour to the stair floor covering is chosen. A luminance contrast strip that provides a strong visual clue of the tread/riser intersection must be included. Stair Nosing: Deep reach nosing for top step or landing area installations. 10 12' sections per carton. We are 100% Australian owned and operated with manufacturing/exporting facilities in Northern NSW. Costs. These state that the tread should measure between 50-65mm and the riser 30-55mm. The documents indicate that there should be at least 30 points difference between the Stair Nosing LRV and that of the floor covering, e.g. Stair nosings are not allowed to project beyond the face of the riser. The principle and an overriding requirement is contained in the Building Regulations (Document K) where it is stated that: “Stairs, ladders and ramps shall be so designed, constructed and installed as to be safe for people moving between different levels…….” – Jump straight to this section of Part K. Which in lay terms (and for the partially sighted in particular) achieving this requirement means that the Stair Nosings create a ‘ladder effect’ to the stairway when viewed from either the top or bottom. The radius of curvature at the leading edge of the tread shall be 1/2 inch (13 mm) maximum. An extensive selection of sizes with nosings, risers and reducers allows you to create any staircase and fulfill your unique elevation, height and aesthetic requirements. For individual product information and further details visit Quantum Floorings range of stair nosings on SpecifiedBy. This Standard sets out minimum design requirements to provide access for most people with disabilities and addresses a wide range of building design elements. Absolutely not. (Actually there is a small variance between the documents, but the consensus is now that the dimensions as shown meet the requirements). This ensures there is a large enough ‘band’ on the nose of the step. This helps create the ‘ladder effect’. APP. Visually Impaired Safety Treads meet California Disabled Access Regulation, Title 24, Section 3306 for the visually impaired when used with contrasting strip color. This is to give a visual warning to pedestrians of the change in height from step to step or from landing to step. The change in level can be clearly highlighted with a nosing that contrasts with the surrounding tread and riser materials. Stair risers must be opaque. Risers shall be sloped or the underside of the nosing shall have an angle not less than 60 degrees from the horizontal. 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: Two (or more) continuous steps would be considered a stairway and will trigger AS1428.1 requirements for TGSIs, handrails, and stair nosing. Full stair non slip treads are also available for industries where the floor may become excessively slippery. When located at the front of a stair nosing, the luminance contrast strip cannot extend down the riser more than 10mm. To meet the requirements of AS1428 the stair nosing must be a contrasting colour of 30% to the stair. 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. A contrasting marking stripe shall be provided on each tread at the nosing or leading edge such that the location of each tread is readily apparent... 2017 LA City Fire Code > 10 Means of Egress > 1029 Assembly > 1029.13 Assembly Aisle Walking Surfaces > 1029.13.2 Stepped Aisles > 1029.13.2.3 Tread Contrasting Marking Stripe Safety Step is a premium provider of non-slip stair treads, non-slip ladder rung covers and non-slip floors & ramps based out of NSW Australia. The tread is the surface of the Stair Nosing which receives ascending or descending footfall. 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. The colour of the Stair Nosing is required to differ from that of the floor covering. PACKAGING. According to the 2007 NYS Stair Code: 1009.3, the nosings or leading edges of treads shall have a distinctive marking stripe, different from any other nosing marking provided on the stair … Stair tread nosing projection past vertical riser below (3/4″ to 1 1/2″) required on stairs with solid risers. 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. Nevertheless, specifiers should be encouraged to follow the guidelines wherever possible, since Stair Nosings that meet these guidelines do actually help to make a stairway safer and thereby reduce the element of risk for users ascending or descending. The strip must measure two inches wide while remaining parallel to the nosing of each step and must possess anti-slip features. since Stair Nosings that meet these guidelines, https://www.specifiedby.com/building-regulations, http://www.brebookshop.com/details.jsp?id=144607, BS8300:2009+A1:2010 – Lighting of stepped access & slip resistance, BS9266:2013 – Design of accessible and adaptable general needs housing, Building Research Information Paper – IP15/03: Proprietary nosings for non-domestic stairs. This helps create the ‘ladder effect’. These ‘guidelines’ are just that – guidelines. 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. This guest post on Stair Nosings was authored by the technical team at Quantum Flooring Solutions. The regulatory documents give details of the dimensions for these approach tactile areas. NZBC D1.4.1.7 (b) “Leading edges of treads or nosings (if any) on accessible stairways shall be colour contrasted with the rest of the tread.” Unsure what’s considered colour contrasting? Figure 18 (a) Flush Riser. Bull nosed steps – these can create a trip hazard to partially sighted users, who use their foot to find the nose edge of the step. We offer you the world’s leading range of products that enable people to move within and to-and-from buildings in the safest possible way. If the nosing does protrude, it should be by no more than 25 mm However, minor interruption to that strip is tolerated provided that the interruption does not adversely effect the luminance contrast effect. There are two recommended tests that can be carried out to determine the slip resistance of a flooring material. Safety Step is widely appreciated as worldwide leaders in our specialist industry, bringing innovation and leadership to the anti-slip and emergency way-finding industries with long involvement at Australasian Standards management and regulatory level. 110 Chelmsford Road, Rock Valley, NSW, Australia, Click to see our Ladder Rung Anti-Slip Covers. Gradus stair edgings (stair nosings) can help to reduce accidents on stairs as well as helping to provide an ‘inclusive’ environment giving access to all building users. Our products improve safety and government standards compliance at competitive prices. If possible, step nosings that protrude over the tread below should be avoided. B. Stair nosing treads shall be [solid] [ribbed]. Poor visibility can cause people to misread the edge of a step, causing them to fall. For people who are blind or have low vision, contrasting and tactile warnings assist with the detection of the presence and proximity of stairs. Shiny metal – as these can create glare in artificial or direct sunlight. In such instances the aim. The strip needs a luminance contrast of at least 30% with respect to the background material. The chart below summarises these as they appear in each document. intersection by more than 15mm. The five aspects/topics (see chart above) which contribute to the attainment of this ‘ladder effect’ are: Building Regs (K&M), BS8300 and BS9266 When located at the front of a stair nosing, the luminance contrast strip cannot extend down the riser more than 10mm. If the stair treads are not slip resistant, installing a slip resistant painted nosing would be a cost efficient solution. 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’. Double channel Stair Nosings (too wide to meet the 55-65mm requirement). This means the contrasting strip must be a ‘single strip’ and of ‘ one colour’ only. nosing and riser profile for commercial stairs Nosing in commercial stairs must have curvature or a bevel of no less than 1/16 inch but not more than 9/16 inch when measured from the foremost projection of the tread. Any stair or floor covering that is not rounded to 5mm (min) to 10mm (max) as shown in the diagram below requires a stairnosing. The luminance contrast strip must be between 50mm and 75mm wide and cannot be set back from the tread/riser. C. Stair nosing tread surfaces shall be slip resistant. [Image: The elements of stairs] For buildings other than dwellings, step nosings should be made visually apparent by using a contrasting material on both the tread and the riser a minimum of 55 mm wide. However, extending the nosing too far, which was sometimes done on excessively steep stairs of old houses, creates a protrusion that is a trip hazard when ascending or descending the stairs. Contrasting nosings on both the tread and the riser will assist building users to identify a staircase and determine where there are changes in floor level. Stair Tread nose curve radius =< 9/16" or <= 1/2" in some codes. It is not simply the difference in the colour contrast but the difference in the light-reflective properties of each colour. Is the depth of the stair nosing limited to 10mm at the front like this? Nosings shall project no more than 1-1/2 in (38 mm). Our TYPE 24 safety strip meets all the requirements of California Title 24. 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”. Since 1993 we have led the industry in anti-slip safety products and have played a leadership role in the industrial safety industry. D. Stair nosing treads shall be removable and replaceable. All photoluminescent treads require exposure from UV or natural daylight to charge the material. The luminance contrast strip must be between 50mm and 75mm wide and cannot be set back from the tread/riser. Consider providing visual contrast on tread nosings, or at the leading edges of treads without nosings, so that stair treads are more visible for people with low vision. Corduroy Tactiles (not the blister finish– the type used on pavements at crossings) should be installed as a hazard warning surface on the top and bottom approaches of the staircase, which will warn pedestrians that they are approaching a staircase. For example, consider adding a different brick or tile to your hard surface stair nosing or entryway. After just 5 minutes of exposure in a reasonably lit area, Ecoglo®’s photoluminescent stair nosing will glow brightly for 2.50 hours – providing clear egress lighting and instructions in the event of a power outage and exceeding emergency egress requirements. Nonetheless, sizes ranging from 2 to 12 inches are commonly available for nosings and treads and need to be selected according to the size of the stairs and their construction accordingly. Technically they are not mandatory; evidence of this is common in the market as so many installations would not meet the criteria outlined above. 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. Visual contrast on stair nosings or the leading edges of treads is helpful for people with low vision, but it is not required by the Standards except at escalators in rail and fixed guideway stations which must meet the ASME A17.1 … 7.2.2.5.5.3 Exit Stair Handrails 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. Is color contrast required for stair nosings? The tread material used in a Stair Nosing is important for the safety and performance of a stairway. Does the luminance contrast strip have to be in one piece? Providing a P4 slip resistance rating, suitable in both wet and dry conditions the range meets the requirements of both AS4586:2013 (slip resistance) and AS1428.1 (Design for accessibility). 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. Either of these can be used to give an indication of the slip resistance of a material, although the Pendulum method is limited in so far as it cannot be used to test material on site. Quantum uPVC and Aluminium Stair Nosings (stair edgings) help to make a stairway safe. This limitation is to avoid confusing the location of the leading edge of the tread. The State of California stripping code for the visually impaired calls for all stair treads to have an anti-slip strip of contrasting color 2 inches wide, parallel to and not more than 1 inch from the front nose of each step. Specifically Title 24 addresses the visually impaired aspect of nosings with a variation on the Standard A117.1 requirements. The stair treads and nosings are filled with photoluminescent silicon carbide and epoxy mixture to create an anti-slip surface that illuminates stairways in the event of an emergency. This can help users identify the nose of the steps more safely when descending or ascending. PROFILE.

Carpeted stairs can be inlaid with contrasting colors to signal the edge of the stair tread. Stair nosings must be continuous across the full width of the stair tread. Browse the stair gallery to take a closer look at completed mesquite wood staircases. What is meant by ‘stair nosings cannot extend beyond the front of the tread’? The body of the stair nosing can extend any distance down the riser. The full title is Australian Standard Design for Access and Mobility Part 1: General requirements for access – new building work. At the nosing, each tread shall have a strip not less than 50 mm and not more than 75 mm deep across the full width of the path of travel. DESCRIPTION. Some zoning laws require it only on the top and bottom … Tape may be … 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. The greatest stair tread nosing projection shall not exceed the smallest nosing projection by more than 3/8 inch (9.5 mm) between two stories, including the … should be to ensure there is a good contrast Stair Nosing on the steps – at least creating a positive ladder effect in order to clearly identify each step. As well as servicing a strong domestic client base in Australia we also support a reseller network in over 12 countries. The colour variant should be at least 30 points (where black to white is 100 points) on all treads. The stairs in the photo below had a 2-1/2” nosing and were truly awkward–and also dangerous–to use, especially when descending the stairs.
