Tactile paths for exterior spaces are made from perforated sheet metal, AlMg2 alloy, ≠ 4 / 5mm. Mounted on a prescribed width of 40cm. They are anti-slip and are made into two different tactile surfaces, also recommended in the Rulebook. Their purpose is for the independent movement of blind and sandblind persons in the outer space from parking places for persons with special needs to the entrance to the building. They provide complete signaling to the blind and sandblind persons by white stick and touching by legs while walking on them.
It is important to note that the tactile surface in the outer and inner paths is designed to be identical. All dimensions: track width, line width, line spacing, height, circle diameter, spacing and arrangement of circuits are identical in the outer and inner paths. So the blind persons have identical signaling both from the outside and inside the object. The difference can be felt only by the hardness of the material: metal - rubber.
External tactile paths are extremely resistant to external conditions; sun, rain, snow, ice ... wear resistant and anti-slip.
By special treatment and permanent deformation of the surface, prior to cutting and machining of parts, we received extremely anti-slip material according to the testing of the Accredited Institute for construction materials testing, we got the anti-slip of materials with high R12, which is very important for external conditions of paths using in conditions of rain, snow, eventual mud, etc.
They are maintaining with standard hygiene products which are diluted and cleaned with water.
They mount on the ground (concrete, ceramics, marble, asphalt ...) with steel anchors and screws of quality A2 (inox, prohrom, stainless steel ...) with head count and inbus screw. They are mounting by gluing of two-component adhesives to ideally flat surfaces (marble, ceramics ...). The adhesive is of superior quality, stable, impact and extreme weather conditions resistant ... used in production of trains, bonding of formwork for the metal structure of the train.
