Installation of Guardrail Beams with Posts

For guardrail installed in soft soil condition, we suggest the post without flange plate is used. The barrier system can be fixed quickly with post anchors.
For solid concrete road surface installation, we suggest that the steel post with plate is used. It can be fixed to the beams with bolts.

Installation of Round Post: One end of the Round post is connected to the guardrail plate by bolts, nuts and connectors, and the other end is embedded in the earth or fastened to the road surface by flannel, thus playing a supporting role and effectively preventing vehicles or pedestrians from rushing out.
