What is the difference between guiding and warning surfaces?

Guiding surfaces are ribbed and show the direction of travel. Warning surfaces are blistered and signal a decision point — a kerb ramp, crossing or stair head — where the pedestrian should stop and check. Used together they form a continuous accessible route.

Which standards apply?

In Turkey, TS ISO 23599 covers tactile walking surface indicators and TS 13536 carries installation recommendations. Pedestrian way and pavement schemes also follow the national regulation on the design of pedestrian ways and pavements.

What size do you supply?

The catalog lists the 30x30 cm tile format, which is the common choice in municipal and public projects. For other sizes or colours, send your requirement to our sales team.

How are project quantities calculated?

Quantities are worked out by square metre from the length of the guiding route and the decision points that need warning surfaces. Pavement width, number of crossings and route continuity drive the plan — send your dimensions and we will help with the split.

Tactile Walking Surfaces

Guiding and warning tactile walking surface indicators help pedestrians with vision impairment follow a route and stop at hazards. Supplied in 30x30 cm tiles for municipal and project work.

Guiding Surfaces and Warning Surfaces

The two types work as a pair. Ribbed guiding surfaces show the direction of travel and carry the route forward; blistered warning surfaces say 'stop and check' at decision points such as kerb ramps, crossing thresholds, stair heads and platform edges.

A correct layout depends on laying both types in the right order and without breaks: the guiding line leads, and the warning surface terminates it before the hazard. Colour contrast matters too — the surface must stand out clearly from the paving for pedestrians with low vision.

Standards and Project Practice

In Turkey tactile walking surfaces are covered by TS ISO 23599 and by TS 13536, which carries installation recommendations, together with the national regulation on the design of pedestrian ways and pavements. The 30x30 cm tile format is widely used in municipal and public projects.

Pavement renewal, public square, terminal and campus projects are planned on a square-metre basis. Send us your project dimensions and our sales team will help split quantities between guiding and warning surfaces.
