Tactile Indicators – Polyurethane Studs

Tactile Ground Surface Indicators

Tactile Indicator Single Studs – TGSI Polyurethane Concentric Pattern

Tactile Indicator Studs TGSI’s

Poly Studs are built to withstand tough environments like busy shopping centres, train stations and schools, indoors or out, with an appealing range of colours to match any décor and meet luminescence contrast codes. They are anti-slip, easy to install and made from long-lasting high impact thermoprene.


  • A distinctive colours to suit every look – black, white, terracotta, blue, yellow, grey, beige and red
  • Suitable for multiple installation applications – concrete, timber, carpet…
  • Easy drill and press fitting stud
  • Suitable for external or internal use
  • Highest slip rating (R13)
  • UV stabilised material to protect against the sun Compliant with Australian standards and codes Manufactured in Australia

Don’t’ forget
Tactile Ground Surface Indicators must achieve the following contrasts against substrates.

30% – Integrated Tiles such as the peel and stick or fibreglass re-enforced.
45% – Discreet (Individual TGSI’s) studs , some people call them dots.
60% – Composite Discreet (Individual TGSI’s usually with a different colour insert) For example a stud that may have a carborundum or epoxy insert in the dome.


Studs are individual discrete studs, or dots that use an expansion anchor or stem to fix to the pedestrian pathway.
They are drilled directly into the ground.
The studs have sloped sides with co-centric rings for slip resistance.
They are very robust and have in some cases offer a more  architectural and aesthetic appeal.





How many tactile studs are there per square metre?
With TGSI’s single studs, you will require 400 per square metre OR if you have a width of 600mm wide you will need 240 per lineal metre.
With Directional bars you will require 45 per square metre. See calculator above.


             We ship Australia wide via TNT Road Express or Century Couriers



Installation of the individual TGI’s, studs.

We recommend the use of a template for easy install.

Our templates are made of ACM (Aluminum composite material (ACM) which  is a three-layer composite sheet with plastic as the core layer)

  • Size is 1200 mm x 600 mm
  • 4 mm thick
  • Suitable for shaft diameter of 8mm single tactile studs
  • 24 holes across x 12 holes down-Total of 288 holes.

You can use these templates twice, as after using the drill, the holes may become slightly larger.

Therefore one template can effectively drill 576  holes (used twice per hole).


Hazard or Warning tactiles

Warning or Hazard Tactile Indicators (TGSI’s) are required to cover the full width of the path of travel, for example handrail to handrail on a flight of stairs, ramp or escalator.

On stairs and ramps, the front to back measurement also know as the depth of a warning tactile area depends on the amount of clear travel immediately before or after the stair or ramp, that a pedestrian will traverse.

If the approach or landing is 3 metres or greater, the minimum depth of tactile indicators is 600mm. If the approach or landing is less than 3 metres, the minimum depth of tactile indicators is 300mm as opped to the above of 600mm.

If a landing is less than 3 metres in depth and there is a continuous handrail on both sides, no tactile indicators are required.

In a streetscape or external environment, the minimum depth of tactile indicators is 600mm.

On busy roads to give more warning of the up-coming hazard you can install tactiles greater than 600 mm in depth across the full path of travel.

Stairs where the approach is less than 3 metres, but only one handrail, requires one row of tactiles.

Stairs with handrails on both sides , and the approach is less than 3 metres means that no tactiles are required.
