NOKIN Bi-directional Aluminium Road Studs are made of durable aluminium alloy . It is designed in such a way that when installed into the asphalt the fixation element prohibits the road stud from rotating. They have a high degree of visibility during the day because of the white or yellow colour of the body, and during the night because of the prismatic acrylic reflectors that they incorporate. In case of rain they retain their reflective characteristics because of the raised body from the surface of the asphalt.
