Bridge Edge NJBP – H4b for Artworks

This reinforced concrete bridge edge barrier is CE-marked and classified in H4b containment class, designed for use on artworks. The barrier is prefabricated using concrete with a C35/45 resistance class and reinforced with B450C and C45 steel.

At the top there is a rolled bar of 28 mm diameter, pitch 10, made of C45 steel embedded in the concrete which, by means of a suitable sleeve made of PRBO 35MnPb 10 steel, allows the mutual connection at the head between adjoining elements. A further connection is made to the lower kerb by means of an M20 grouting bar in cl. 8.8 steel and by means of a steel plate with dimensions 60x80x8 mm.

The NJBP-H4B barrier is equipped with a steel handrail tube at the top.
