Is the riser flooring fire rated and can you advise thickness and mass per m2 for loading consideration

This product isn't fire rated. These are not load bearing due to designed for vertical applications. Assuming you are looking of grp anti-slip plates you could consider Anti-Slip Flat Plate . These contain a Fire Resistant Additive resulting in a Euro Class 1 fire rating in accordance with ISO 9239-1 and ISO 11925-2. This performance is equivalent to ASTM E84 class 1 and BS 476 part 7 class 2 flame spread and in effect gives a 25 minute burn time on the material.

Cover stair risers with an extremely durable slip resistant surface. Firm-Step Riser Plates finish the job to give vertical surfaces the same long lasting appearance. They have a smooth finish to avoid scuffing, and do not normally need to be cut to height as the top edge is hidden behind the step nosing.

ColourPicker Explained

In general we sort colours for products into 2 main groups - ‘Ready Mixed’ and ‘Tinted’.
Tinted colours will always be more expensive than Ready Mixed colours as they need to be produced at the time of order using a tinting machine dispensing colourant into a base*.
During busy periods, this means that tinted colours could take longer, for example – a ready mixed colour ordered on a 3-5 day delivery might arrive within 3 days, however a tinted colour might take the full 5 days to arrive.

To find Ready Mixed colours, search "ready mixed" or select the Ready Mixed 'colour chart'. To see Tinted colours select a colour chart such as RAL, BS, NCS, etc. or search for a colour/hue to see available or related options.

To ensure fair pricing, we split colours into ‘Price Bands’ to group together similar priced colours. If you wish to search for the cheapest tinted colours, always select Price Band 1.

We make every effort to list all available colours, however we also offer a colour match service which can be accessed by contacting our Technical Team on 0113 245 5450 (option 2) or emailing [email protected]

*Colours are sold in the nearest tin size but actual paint volume per tin may vary up to 10% depending on colour

Adhesive Fixing

Apply an approx. 6mm bead (this may need to be increased dependant on the substrate conditions) of Watco Adhesive Mastic around the periphery of the underside of the Firm-Tread approx. 25mm in from the edges
Riser Plates should be fitted before any of the stair treads
Push these onto the riser as far down as they will go. When Firm-Tread Step Covers are fitted these will hold the Firm-Step Risers in position

Mechanical Fixing

To Timber:

Lay out all pieces of Firm-Step material on the substrate upside down
Apply the Watco Adhesive Mastic as stated above. Turn the material over and secure to the substrate, applying body weight to expel any air
Mark Firm-Step where holes are to be drilled, Using a 6mm masonry drill bit, drill through Firm-Step only exposing the substrate
Using a 3.85mm drill bit, drill through the stair tread as stated above (for hard wood, you may need to pilot hole)
Once all treads have been pre-drilled, using stainless steel screws (Stainless steel Pozi head 32mm x 4.2mm screws), screw the material down and aim to make the screw fixings flush with the top surface

To steel checker plate (or similar):

Lay out all pieces of Firm-Step material on the substrate upside down
Apply the adhesive as stated above. Turn the material over and secure to the substrate, applying body weight to expel any air
Using a 3.85mm drill bit, drill through the stair tread and steel checker plate
Once all treads have been pre-drilled, using stainless steel screws (Stainless steel Pozi head 32mm x 4.2mm screws), screw the material down and aim to make the screw fixings flush with the top surface.

To concrete or ceramic:

Lay out all pieces of Firm-Step material on the substrate upside down
Apply the adhesive as stated above. Turn the material over and secure to the substrate, applying body weight to expel any air
Using a 6mm masonry drill bit, drill through the stair tread and into concrete
Push raw plugs into the 6mm drilled hole and tap to ensure that the raw plugs are flush with the substrate
Once all treads have been pre-drilled, using stainless steel screws (Stainless steel Pozi head 32mm x 4.2mm screws), screw the material down and aim to make the screw fixings flush with the top surface

To open mesh:

To avoid hitting a load bar of the open mesh, place the Firm-Step material on the open mesh area, then from underneath, mark where you want the fixing to go
Then using a 10mm drill bit, drill through the Firm-Step and ensure it is in the centre of the open mesh
Once all treads have been pre-drilled, using 40mm dome
head bolts push them through the pre-drilled holes
Using a 40mm diameter washer and a nylock nut, tighten up from underneath
