EDSP 2.0 Single Side Highway Guardrail

Single Side Highway Guardrail, also known as W-beam guardrail, is a type of crash barrier designed to prevent vehicles from leaving the roadway. The standard design consists of corrugated sheet steel beams, usually galvanized, with posts, blocks, and spacers mounted to the beam in a specified arrangement. The dimensions of these components vary depending on the specific application, but typically include widths of 1220 mm, 1250 mm, 1320 mm, and 1500 mm, heights of 310-325 mm, and various post and block configurations.

We supply single sided guardrails manufactured in EN 1317 standard popularly used for high way constructions. Single Side Highway Guardrail - EDSP/2.0 is our specialty guard railing product for highway projects in Georgia and other countries.

EDSP 2.0 Single Sided Road Barrier System basically consists Beam Guard Rails with spacers, preventing vehicles from going off the road on one side of the road and traffic islands.

EN 1317

To be implemented within Europe, Vehicle Restraint Systems (VRS) have to meet the requirements of the European Standard EN 1317. The systems have to undergo crash tests, whose parameters and acceptance criteria are defined by the norm. Depending on the test results, the systems are divided into performace classed. Each type of VRS is evaluated in an individual part of the EN 1317.

EN 1317-1 Terminology an general criteria for test methods
General part of the standard, specifies characteristics of test areas and vehicles
