HIGH QUALITY OF GUARDRAILS IN ACCORDANCE WITH THE REQUIREMENTS OF GOST AND TECHNICAL SPECIFICATIONS

ДThe road guardrails serve to prevent the vehicle from moving off the side of the road, colliding into massive obstacles and structures located on the side of the roads and in the rights-of-way, or to prevent the vehicle from moving through the traffic strip, collisions with outbound traffic. This structure will protect vehicles from collision and will serve as an effective tool for preventing traffic accidents.




ROAD GUARDRAILS SERVING AS BARRIERS MANUFACTURED BY THE ZAVOD PRODMASH ARE A "MAJOR BREAKTHROUGH" WHHEN IT COMES TO SAFETY OPERATION OF RUSSIAN AUTOROADS, IN ACCORDANCE WITH THE REQUIREMENTS OF GOST.

An important design feature of the road barrier guardrails is the presence of a detachable cantilever construction that improves the kinematics of the clash of the vehicle with the barrier in the event of an accident, thereby ensuring a safe push back of the car to the road in the event of a collision with the barrier. During a clashing with a road barrier guardrail, the girder and the cantilever construction get detached from the metal prop, so that the car does not "dive under" the girder, ensuring the survival of the passengers.

It is worth mentionin that the use of a deatachable cantilever in the complex construction of road barrier guardrails increases the margin of the operating holdup of the barrier, since the critical angle of inclination of the barrier is minimal and the car does not smash through the road guardrails. The road barrier guardrails manufactured by the Zavod Prodmash are distinguished by its long servicability due to the application of hot-dip galvanizing in the process of product manufacture.
