Pravina Spring Post is made of special Flexible material (Poly-Urethane). It can be quickly restored to its original shape without doing any damage to spring post as well as vehicles in case of high speed collisions. Two / Three Bands of reflective tape are pasted on the spring post. It keeps excellent mechanical & chemical properties such as impact resistance & tensile strength even under bad weather conditions with wide ozone resistance (UV stabilized) so that it is not discoloured. The base of spring post is fixed on the road surface with the help of three bolts and special epoxy bond. The bond is so strong impact after installation.
