Basically, any tactile indicators are meant for offering a certain warning signal to pedestrians and particularly those who are visually impaired. They are generally installed on continuously accessible paths and offer certain directional information through foot contact or through a cane used by blind people.
There are following two types of tactile indicators:
1. Surface applied
These kinds of tactile indicators are usually screwed and glued on top of a certain stable surface. These tactile indicators can be quickly installed, are simple to retrofit as well as can withstand very tough pedestrian use.
2. Cast in place
These types of tactile indicators are applied while curing any wet concrete. As the concrete will get cured, the tile will become mechanically fixed to any finished substrate.
OLEJÁR is a company who is engaged in manufacturing of aluminium tactile strips and they are widely used in various road projects.
Long-lasting, stable functioning is ensured by individual tactile guiding lines for the floor in the longitudinal rib shape. These guiding strips are available in a variety of size and shapes, with or even without pins, in the form of self-adhesive or with screw apertures. Smooth, milled, grooved, and with a colour inlay in the product are some of the patterns available.
Coloured and non-slip inserts are available for aluminium warning studs, allowing you to choose the best contrast value for installation. You can also use a different insert for the aluminium guide strips or warning studs if you desire it.
All tactile indicators’ surface patterns and inserts meet the necessities for anti-slip qualities. The coefficient of friction will be R10/R11/R12/R13, depending on the specification.
- Interiors should have the least anti-slip value: R10
- Exteriors should have the least anti-slip value: R12.
Aluminium
Wrought aluminium-magnesium-silicon alloy AW-6060 T6 is a type of wrought aluminium-magnesium-silicon alloy. It can be shaped by extrusion, rolling, or forging, but it is not used in casting as any wrought alloy.
Aluminium alloy is a heat-treatable medium-hard alloy. It possesses excellent corrosion resistance in the atmosphere and in seawater, as well as excellent weld-ability, cold formability, and eloxation reaction.
Which will be the right tactile indicator?
If you are looking for any outdoor application then the following tactile indicators will be preferred:
1. Polyurethane tactile indicator
Usually, you will find polyurethane tactile indicators quite tasteful solutions because they are hard wearing and also can be used for both indoor as well as outdoor applications. You can also use them on the existing surfaces.
Also, it is possible to manufacture them in any chosen colours. Although for road safety purposes mostly yellow colour is a preferred one.
2.Stainless steel tactile indicator
Stainless steel tactile indicators are considered a premium product and they will also provide a stylish solution. Normally these indicators are manufactured by using a very high-quality stainless steel that is also marine-grade material.
Also, similar to polyurethane indicators these stainless steel tactile indicators can also be used for both indoor and outdoor applications. Also, stainless steel tactile indicators can be installed for both new as well as existing substrates.
