This Genesis stair nosing provides a safe, sturdy edge finish for stair treads covered with tiles or similar materials. The flange sits beneath the tile, while the upper part protects the tread tile and prevents water from entering the joint. The top has a grooved walking surface for extra grip and a raised lip that protects the upper edge of the tile. This version is intended for a tile thickness of 12 mm and has a length of 2.8 metres. The finish is matte silver.
Product & function
The profile is extruded from AA 6063 T6 aluminium and anodised according to DIN 17611. For outdoor use, the manufacturer recommends a powder-coated finish.
Application & compatibility
The profile is intended for tiled stair treads. Choose the version that matches the thickness of your tile, so that the top of the profile is flush with the tile surface. We do not supply corner pieces for this series. Cut the corner at a 45-degree miter; using a miter box will help you maintain a consistent angle.
Use & key considerations
- Tile adhesive usually provides sufficient adhesion.
- If extra security is desired, the profile can be mechanically fixed.
- Ensure that the flange sits completely beneath the tile and that the tile is flush.
Aluminium is sensitive to alkalis. Cement-based materials become alkaline when combined with moisture, so remove adhesive and grout residues from visible surfaces and ensure that the profile is fully embedded. In the event of chemical or mechanical loading, first check whether aluminium is suitable for the situation. No special maintenance is required. An oxide film can be removed with a standard polishing agent, but it will return. Damaged anodising can only be repaired by recoating.

Frequently asked questions
Which profile thickness do I need? The thickness of the profile matches the thickness of your tile. Measure the tile and choose the version that fits; the profile must not protrude above the tile surface.
Can this profile withstand moisture? Aluminium is resistant to normal moisture exposure in bathrooms and kitchens. However, be aware of fresh cement and grout residues: they become alkaline when exposed to moisture and can damage the surface. Wipe them away before they have hardened.
How deep should the profile be embedded in the adhesive? The fixing flange should be fully embedded. After pressing it into place, apply another layer of adhesive over the flange to ensure there are no voids behind it.
Can I cut this profile to size? Yes. Cut the profile with a fine-toothed saw and neatly finish the cut edge.
