Brass Tactile Strips
280 mm solid brass guiding bars with linear pattern; stem or self-adhesive fixing.
View specifications →Solid machined brass warning studs that bring a natural gold tone to luxury hotels, airports, museums and heritage interiors while providing the same tactile safety function as stainless steel.

What they are: Brass tactile studs are warning domes machined from solid brass bar, Ø35 mm and 4.5 mm high, installed on a 50 mm grid to mark hazards and decision points. Brass gives a warm gold colour that complements stone, timber and heritage finishes. MetalX supplies them with a stem for drill-and-fix installation, a poly sleeve, or 3M self-adhesive backing, with concentric ring or carborundum-insert tops. In some markets the same product is called a warning button, tactile button or tactile dome; the terms are interchangeable.

Also known as: warning buttons, tactile buttons, tactile domes, truncated domes and tactile warning indicators. Whichever term your specification uses, the product on this page is the same brass tactile studs.
Architects specify brass tactile studs when the floor is part of the design statement: a hotel lobby in cream marble, a museum gallery in oak, a heritage railway station being restored. Brass is warm, machines to a crisp pattern and develops a soft patina that suits traditional interiors. MetalX machines each stud from solid brass bar in Mumbai, so the colour runs through the whole stud and cannot wear off as a plating would.
Functionally the studs are identical to our stainless steel tactile studs: Ø35 mm top, 4.5 mm height, 50 mm grid, with concentric rings for slip resistance or a carborundum insert for the highest wet grip.
Five standard configurations are stocked; diamond and plain tops can be machined to order.





Untreated brass tarnishes slowly to a darker bronze tone. Many clients prefer this natural patina; others specify a clear lacquer or ask us to polish periodically. Brass is also naturally antimicrobial, which is one reason it is chosen in healthcare interiors. For outdoor coastal sites, or where zero maintenance is essential, consider gold finish (PVD) stainless steel studs, which give a similar colour with stainless steel corrosion resistance.
Choose brass for indoor premium spaces where colour matters and cleaning is regular. Choose stainless steel for exteriors, transport platforms and high-traffic public areas. Our article brass vs stainless steel tactile studs compares long-term performance.
Brass is a copper-zinc alloy with a colour that sits between gold and bronze. Set into cream marble, sandstone or oak it looks like an intentional inlay rather than a safety fitting, which is why interior designers ask for it in hotels, galleries, banks and restored railway stations. The alloy is also naturally antimicrobial, a point in its favour in healthcare and hospitality interiors, and it machines to a crisper pattern than stainless steel. What it does not do is stay bright without attention: brass darkens to a bronze patina, quickly in humid or salty air and slowly in a dry, cleaned interior.
| Location | Brass suitable? | Notes |
|---|---|---|
| Hotel lobby, banking hall, gallery, theatre | Yes | The classic use; daily cleaning keeps a soft lustre |
| Heritage station interior, museum | Yes | Patina is usually welcomed |
| Corporate reception with warm stone or timber | Yes | Consider lacquer if a bright finish is wanted |
| Covered entrance canopy, dry climate | Acceptable | Expect some darkening |
| Open pavement, platform edge, coastal site | No | Tarnish and verdigris; use SS 316 or PVD gold |
| Pool deck, spa, wet areas | No | Persistent moisture; use stainless steel |
Concentric rings are standard and give good grip. The carborundum insert adds a black abrasive centre, which both improves wet slip resistance and solves the contrast problem that gold-toned studs can have on pale marble. Stem fixing into drilled holes with epoxy is used on stone and concrete; the poly-sleeve version speeds installation on rougher substrates; the 3M self-adhesive version lets a hotel retrofit a stair landing overnight without drilling its marble.
Brass studs sit on the same 50 mm grid as all our studs: 400 per square metre and 240 per running metre of a 600 mm-deep field. A grand staircase 3 m wide needs about 720 studs at the top and 720 at the bottom.
“Tactile warning studs: solid machined brass, Ø35 mm top, 4.5 mm high, concentric ring top [or carborundum insert], natural polished [or clear-lacquered] finish, Ø8 mm stem set in epoxy anchor [or 3M self-adhesive backing], at 50 mm centres in fields 600 mm deep across the full hazard width, starting 300 mm from the nosing. Manufacturer: MetalX Engineering Inc., Mumbai, or approved equal.”
Hotel lobbies and banking halls in Mumbai and Delhi, restored heritage stations in India, corporate headquarters in the Gulf, and gallery and museum interiors in the UK.
Identical to stainless steel studs: mark the 50 mm grid with the template, drill, clean, fill with epoxy and press the stud home; or peel the 3M liner and press onto a clean, smooth floor. Protect polished brass from mortar and acid cleaners during construction.
Brass studs share the Ø35 mm, 4.5 mm, 50 mm-grid warning geometry of AS/NZS 1428.4.1 and ISO 23599, and are available in an ADA truncated-dome profile. Note that gold-toned studs on pale stone may not achieve the luminance contrast some standards require; we can supply carborundum-insert tops in black or a contrasting surround detail to satisfy contrast requirements.
Untreated brass slowly develops a darker patina, especially outdoors or in humid air. Indoors with normal cleaning the change is gradual and often welcomed. A clear lacquer or PVD protection can be applied if the bright finish must be maintained.
They can be used outdoors in covered or dry climates, but for coastal, wet or high-pollution sites we recommend stainless steel or PVD gold-finish stainless steel, which keep their colour without maintenance.
Standard Ø35 mm top, 4.5 mm height, laid at 50 mm centres. Ø25 mm and Ø30 mm studs and custom stem lengths can be machined to order.
Yes. The concentric ring pattern is machined into the top for grip. For the highest wet slip resistance choose the carborundum-insert type.
Yes. We supply brass studs with factory-applied 3M double-sided tape for drill-free installation on tile, stone and terrazzo.
Both look gold. Solid brass has a warmer, natural tone and patina; PVD gold on stainless steel is harder, brighter and fully corrosion resistant. Solid brass is usually specified for heritage interiors, PVD for modern exteriors and transport.
Yes. Warning buttons, tactile buttons, tactile domes and truncated domes are regional names for the same product: a raised stud fixed to the floor in a grid to warn of a hazard. MetalX brass tactile studs are supplied under any of these names to the same specification.
Typically 30–50% more than SS 304 studs of the same size, because brass bar is more expensive. Send quantities for an exact quotation.
With neutral floor cleaners and normal machine cleaning. Avoid acidic tile cleaners, which strip brass. Re-polish or re-lacquer if a bright finish is required after several years.
Gold-toned brass on cream marble may not achieve the luminance contrast some standards require. Specify the carborundum-insert type, which has a black centre, or a contrasting border around the field.
Yes. Brass directional strips and 300 × 300 mm brass tiles are machined from the same alloy with the same finish.
