Below are some answers to the most frequently asked questions regarding Tactile Ground Surface Indicators (TGSI):

What is a TGSI?

Tactile Ground Surface Indicators (TGSI’s) are protruding domes or directional bars that are made from various materials which are built into walking surfaces.

TGSI give warning, hazard and or directional information to pedestrians who are visually impaired, through contact on these individuals’ walking aids or feet.

Individuals with limited vision can also use TGSI by identifying the colour contrast of the surface indicators.

When does my project require TGSI?

Legislation for TGSI’s can be found in

  • The National Construction Code
  • The Disability Discrimination Act (DDA); and
  • The Australian and New Zealand Standards (AAS1428 – 2009 Design for access and mobility)

These codes and acts, state that people with disabilities have the legal right to access the building and public facilities in a safe and independent manner.

Responsibility rests on the builders and designers of these buildings to ensure that this access goes unimpeded, necessitating the use of TGSIs.

What are they made of?

Tactile Ground Surface Indicators are made of a range of materials to suit different substrates and environments such as stainless steel, brass,  polyurethane, ceramic and concrete.

Stainless Steel Tactile Indicators, are made from 316 marine grade stainless steel can be used indoors or outdoors, and offer a stylish solution to your tactile needs, or in the case where you expect the indicators to experience heavy duty wear.

Polyurethane indicators are well suited to both indoor and outdoor projects.  They handle almost all kinds of wear and tear well, and come in a range of colour options.
