CAT (CAT Flooring Accessories) is a UK-recognised brand for precision-engineered stair nosings and threshold strips, specified across commercial and residential projects. If you’re searching for CAT stair nosings, this page brings together our most popular CAT aluminium and solid brass profiles-plus threshold options as the range expands.
Quick way to choose the right CAT profile
Material: choose CAT aluminium stair nosings for lightweight durability and versatile inserts, or CAT solid brass stair nosings for premium, heavy-duty performance.
Profile shape: match the stair detail with square edge, bullnose, raked front or ramped designs.
Floor type / gauge: ensure the profile suits your finish (e.g. LVT 2.5mm, carpet, hard floors) and installation requirements-see each product for exact suitability.
