Steel barriers are a road safety system which can be used deployed to separate vehicles from roadworks, pedestrians, other vehicles and anything which could potentially cause a collision in the situation where a vehicle loses control. There are many variables to consider when selecting a barrier system. For instance, in a roadworks scenario which is continually changing, the steel barrier will need to be one that can be re-deployed easily. A full height system may be required where pedestrians and vehicles require separation. M.A.S.S Guard has an option to add a mesh panel to the base unit which acts as extra safety for pedestrians and workers and also provides site security. A median barrier prevents collisions between opposing traffic and needs to absorb impact from both sides and should be easily re-deployable.
