Stair Nosings
CAT manufactures a large range of stair nosings in Brass, Aluminium and Stainless Steel. Stair Nosings are used to protect the edge of stairs and prolong the life of the floor finishes in heavily-trafficked areas. This is mostly in commercial premises but they are also used in domestic locations in conjunction with LVT or vinyl tile installations.
Step Profiles are known by the following names to describe the shape of the front edge of the step:

Nosing Gauges
Stair Nosings are supplied in various thicknesses, the most popular of which are 2.5mm used with vinyl, resin, LVT and ceramic or stone and 5mm used with carpets, carpet tiles and LVT. Other thicknesses are also available, see catalogue for full offering.
Nosing Infills & Light Reflective Values (LRV's)
CAT not only offer stair nosings in solid metal but also with a channel rebate to accept a separate infill which is a slip-resistant material in PVC or metal and is inserted into the channel.
Building regulations require that the stair nosing contrasts with the flooring material by at least 30 points on the Light Reflectance scale.
The Light Reflectance Scale is calibrated from 0 to 100 and measures how much light is reflected from the colour and shade of material where 4.25 = Black and 84.22 = White.
All our carriers & infills have been independently tested and allocated a Light Reflectance Value (LRV) to assist specifiers and contractors in correctly achieving the required contrast to meet current regulations.

Nosing Sizes & Site Measures
CAT usually supply our stair nosings cut to step sizes provided by the customer. These cuts are taken from stock lengths calculated to leave the minimum amount of waste.
For project orders, requiring more than 100 linear metres of stair nosings, CAT offers a site measuring service. Once we have received the order, we will send a surveyor to the site to check sizes and confirm the profile suitability.
Please note that this is location-dependent and is at the discretion of the sales director.

Floor Finishing Trims
Over the last 35 years, the type and number of floor finishing trims on the market have grown from 15 commonly used profiles in 3 finishes to more than 400, some of these in 7 finishes. This has been in response to increasing different types of flooring being offered to the market and more demanding design requirements by interior designers, architects and specifiers.
CAT has led the way, innovating and responding to the needs of the industry, creating imaginative, attractive, functional solutions and always keeping quality in mind.
Our Designer Home Collection of products, aimed at the domestic environment, has become a firm favourite of designers and specifiers.
Floor finishing trims are known by various names and familiarising yourself with the following will assist you in understanding the products and their uses.
Clip-In Profiles
Clip-in Profiles, these are trim systems where a base profile is fitted between flooring materials and a top profile is clipped into the base. Originally used to cover expansion joints in timber floors but now used in many different situations. A concealed fixing system, available as twin tops or ramps. Examples of CAT products are Kliks, Kliks Slim and Spectrum.
Angle Edge & Tag Trims
Angle Edge and Tag Trim. Angles are fitted as a neat definition between two floor finishes. Tag Trim is the formable version of an angle edge that can be curved on-site and is used to make curved outlines in the flooring. We make these profiles with upstands in various heights, from 4.5mm to 25mm. The top edge of the upstand is usually 3mm thick on aluminium and brass angles, 2.4mm on stainless steel. We also offer angles with 6mm and 6.5mm top edges as shown in our Mainline and B6 Brass Capped products.
