BRIDGE GUARDRAILS ARE INSTALLED ON BRIDGES / ROAD VIADUCTS / OVERHEAD ROADS AND SERVES TO PREVENT THE VEERING OFF OF THE VEHICLE FROM THE CARRIAGE WAY OF THESE CONSTRUCTIONS

They also serve to prevent the vehicle prevent the vehicle from moving through the traffic strip and collisions with the outbound traffic on these road constructions. The bridge guardrail can also be installed in the places where it is not possible to install the guardrail into the formation of motorways.




SPECIFIC FEATURES OF BRIDGE GUARDRAILS COMPARED TO ROAD GUARDRAILS ARE:

  • The individual design of the fittings of the guardrail to the fixings of the bridge;
  • Greater demands on the holding capacity (from 250 to 600 kJ);

BRIDGE GUARDRAILS MANUFACTURED BY THE ZAVOD PRODMASH ARE CHARACTERISEDBY BY ITS LONG SERVICABILITY DUE TO THE APPLICATION OF HOT-DIP GALVANIZING IN THE PROCESS OF PRODUCT MANUFACTURE.

The employed specialists of the Zavod Prodmash pay particular attention to the development of bridge fences for each specific road object. This ensures an individual approach to each task, as well as the effectiveness of technical solutions developed by the Zavod Prodmash.
