The H120 road safety barrier is CE-marked and certified in class H4b for both single-lane and double-lane divider. The precast traffic barrier is made of concrete with a resistance class of C40/50 and reinforced with B450C steel.
Mutual connection between adjacent elements is achieved at the top of the barrier using a rolled bar (30 mm diameter, 10 mm pitch, made of C45 steel) embedded in the concrete and an appropriate PRBO 35MnPb 10 steel coupling.
An additional connection at the base of the barrier is made using 2 galvanized steel plates 280x80x10 mm connected by 2 galvanized steel M24 threaded bars and 4 galvanized M24 nuts.
