General description:

Our QA3R anti-slip aluminium stair nosing is designed and manufactured in the UK to meet the needs of a variety commercial and industrial environments. Manufactured from an aluminium profile filled with our unique CarbiGrip anti-slip tread infill. QA3R is available with a range of CarbiGrip infill colours available in Black, Yellow, and white as standard in order to create a high visual contrast to the surrounding subfloor.

Our CarbiGrip infill in QA3R consists of Aluminium Oxide, otherwise known as Corundum the second hardest mineral on the MOHS scale to industrial diamond, combined with other coloured aggregates set in cured resin. The Resin binds the aggregates directly into the QA3R profile resulting in an integral anti-slip infill which is impervious to water ingress. The natural hardness of the aluminium oxide, coupled with its naturally angular shape, creates an slip resistant surface which is extremely durable. The inclusion of aluminium oxide throughout the whole infill creates an incredibly durable anti-slip surface which will far outlast any standard PVC inserts or gritted nosing products with only a surface coated layer such as GRP.

Suitable for use both internally and externally and even the heaviest foot trafficked areas, including public access areas such as Airports, railway stations, sports stadiums, Car parks, Hotels, Schools, Outdoor areas, shopping centres, and heavy industry.

QA3R has a unique modular design that locks together with our other modular profiles, meaning you are able to create a simple stand alone nosing or a full tread cover. Pair QA3R with QA4/QA5 for a complete anti slip system, see images or contact us for help with a modular combination to fit your requirement.

QA3R is available in two finishes of aluminium, standard mill finish or a lightly brushed Satin finish, and can be supplied pre-drilled for fixing upon request (fixings sold separately). Choose from a range of colours to improve visibility, including yellow, black and white; bespoke colours possible on request subject to MOQ, contact the team and we’ll work with you to meet your needs.

QA3R Installation:

The QA3R profile is a heavy-duty option, designed for commercial and industrial environments. Therefore, correct installation is vital to its performance. We recommend that you assess the installation substrate fully before fitting. It should be sound and reasonably level. Any remedial work must take place before installation.

We recommend this specific profile should always be screw-fixed. This ensures stability and minimises the risk of tripping or injury. We also recommend that the profile be bedded with a suitable adhesive, such as our Multitread Adhesive, to reduce or remove the potential rattling sound that can be created. This also provides peace of mind for every user and ensures the soundest installation possible.

We recommend using stainless steel screws with countersunk heads. These will best suit the standard pre-drilled holes provided on our profiles if requested. Upon request we can supply fixing needed for your application method.

The adhesive you choose should be suitable for external use. Always use in accordance with the manufacturer’s recommendations. When only fixing with adhesive, we recommend you use a product with high-strength mechanical properties which has been specifically designed for structural bonding. Cartridge adhesives that are typically used for fixing decorative nosings such as Gripfill or F32 are not recommended.

If you have any questions about installing the QA3R profile, get in touch with the team here today who will be happy to help.
