Guide to Floor Finishing Trims

Over the last 35+ years the type and number of floor finishing trims available within the market has grown from 15 commonly used profiles in 3 finishes to more than 400. This has been due to an ever-increasing variety of flooring on the market as well as more demanding 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.

Example of angle edge floor trims.

Angle Edge and TagTrim®. Angles are fitted as a neat definition between 2 floor finishes. TagTrim® is the formable version of an angle edge which 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, 1.8mm on stainless steel. We also offer angles with 6mm, 6.5mm and 7.5mm top edges as shown in our Mainline® and B6 Brass Capped products.
