Tactile Studs are 'blisters' or raised textured patterns about 5mm high made of any material suitable for footway pavements,and these small humps arranged in a diagonal grid pattern give a warning to visually impaired people and indicate a potential hazard or change of direction or location of amenities such as staircases and elevators,crosswalks and sidewalks as well as public transit stations.Available in stainless steel,aluminium or polyurethane,the tactile studs are highly durable and offer quick conversion from existing standard paving to tactile paving surface.Tactile studs in stainless steel are the ideal choice when seeking a classic architectural look, combined with long lasting performance.
