Open Box Beam Barrier (OBB for short) is also found at the road edge or in the center of highways, motorways or other high speed ways. Unlike box beam, open box beam has been coiled into a trapezoidal section. The trapezoidal rail is connected to the post by the fishplates. Commonly, the rail is supplied in 4.8m and 2.4m lengths. According to EN 1317, post spacing is 1.2m or 2.4m.

Z section post or H post, fishplates, bolts and other accessories are provided at the same time for easy installation. Special request will be available.
