Open Box Beam

Open Box Beam (or OBB as it is often called) is a heavier duty barrier system that was originally designed for Highways use on the approach to bridges and other structures. It is made from thicker 5mm steel than Armco Barrier giving it a more rigid construction.Posts are generally set at 2.4m, 1.6m or 1.2m centres depending on how rigid the finished barrier is required to be. As is shown in more detail below the open backed design of open box beam and the way that the beam is fixed to the post using a clamp plate gives great flexibility in the positioning of the posts.
