Flush Aluminum Stair Nosing for 10 mm Floor Finishes

A grooved aluminum stair-edge profile selected for a 10 mm finish build-up, with a 55 mm tread face, 25 mm front return and rear mounting leg. Compare three finishes and the section interfaces for a flush tread edge.

Flush Stair Tread Face and Underfloor Mounting Leg

55 mm Grooved Tread Face

The selected aluminum tread face is 55 mm deep, with longitudinal grooves across its upper walking surface. It meets the adjacent finish at the same top plane. The grooves are a surface detail.

10 mm Finish Interface

The selected 10 mm build-up is measured from the upper surface of the rear mounting leg to the finished tread top. The mounting leg projects 15 mm behind the tread face, providing a defined interface beneath the adjoining finish.

25 mm Front Return

The front return drops 25 mm from the finished tread top. The selected nominal metal wall is 2.5 mm, with 6063-T5 aluminum and 2700 mm straight bars specified for this profile.

Aluminum Stair Nosing Finishes

Satin-silver, champagne and black selected finishes for the same flush aluminum stair nosing section.

Satin Silver

Satin-silver anodized aluminum is the default. The groove crests and exposed front return share the selected finish reference.

Champagne

The champagne-anodized option uses the same selected section and 2700 mm bar length. A warm metallic tone can be coordinated with adjacent handrails and floor trim.

Black

The black powder-coated option retains the selected geometry. Color, sheen and protection of exposed cut ends form part of the finish schedule.

Floor Build-Up, Tread Edge and Bar Cuts

Match the Full Floor Assembly

Include adhesive or bedding above the mounting leg, the substrate level and the required finished tread plane in the section detail.

Measure the Stair Edge by Run

Schedule the clear width of each stair edge, exposed side returns and any joint locations. The selected 2700 mm bar length is divided into those runs, plus a cutting allowance.

Coordinate Fixing and Edge Support

The nosing, substrate edge, rear leg and adjoining finish need a continuous coordinated support detail. Fixings, adhesive, movement provisions and any required slip testing are project-specific items.

Stair Nosing Supply and Quote

Section and Bar Quantity

Quote the 55 mm tread face, 10 mm finish interface, 25 mm return, 15 mm rear leg and 2.5 mm nominal wall with the required bar count.

Finish and Cut Treatment

List satin silver, champagne or black and identify exposed cut ends. Keep finish samples and any cut-end treatment on the same stair reference.

Cut List and Stair Labels

Separate full bars from any requested cut-to-length work. Tie each cut length, joint and end detail to the stair and tread location.

Fixing Materials and Packing

Itemize any requested mounting materials, protective packing and destination. Floor finishes, substrate preparation and installation labor are outside the profile line item.

Flush Aluminum Stair Nosing Questions

What does the 10 mm dimension describe?

It is the selected distance from the upper surface of the rear mounting leg to the finished tread top. The adjacent finish and its bedding must fit that interface.

How wide is the stair nosing face?

The selected grooved tread face is 55 mm deep from the front edge to its rear edge. A separate mounting leg projects 15 mm farther behind the tread face.

How is the 25 mm return measured?

It is the vertical drop from the finished tread top to the bottom of the front return. The selected nominal aluminum wall is 2.5 mm.

Do the grooves make the stair edge slip-resistant?

Yes. The grooved profile adds grip at the stair edge, where most slips happen. For commercial stairs we can supply versions with anti-slip inserts and the slip test report your project requires.

Which finishes and bar length are selected?

Satin-silver anodized, champagne anodized and black powder-coated aluminum are selected on the same section. Straight-bar length is 2700 mm.

What should a stair-nosing request include?

Include a tread section, full finish build-up, substrate edge detail, stair widths, joints, finish and destination. Add any requested cutting, mounting materials and exposed-end treatment as their own items.
