The ET100 road safety barrier is CE-marked and certified in class H2 and H4b for side edges, H4b single-lane divider, and double-lane divider. This is a precast reinforced concrete barrier with resistance class C35/45 and B450C steel reinforcement. At the top of the barrier, a rolled bar (diameter 28, pitch 10, in C45 steel) is embedded in the concrete, allowing mutual connection between adjacent elements through a specific steel PRBO 35MnPb 10 coupling.
An additional connection is made at the base of the barrier with 2 galvanized steel plates (280x80x10 mm) connected by 2 galvanized steel M24 threaded-end bars and 4 galvanized M24 nuts.
