Road Barriers

Defence-Structures Road Barriers are designed to resist the impact of a 5 tonne truck travelling at 36 km per hour (or a 2.5 tonne truck at 52 km per hour; or a 7.5 tonne truck at 30 km per hour).

They are designed to stop the truck dead in 2m, and to prevent penetration of the protected area. The 2m is the crushing of the truck, not the barrier.

They can have chains or handrails connecting them to stop motorcycles or shopping trolleys. They should be combined with gates, labyrinths, cover from view screens and other defence structures. Keeping potential bombs as far away as possible from the vital areas is an important factor in force protection.

Such road barriers may be accompanied by softer barriers to make them less lethal.

The barriers may be founded in holes filled with concrete, or can be surface mounted on concrete plinths; you will need to describe the emplacement to us before design.

Similar barriers can be built to withstand bigger vehicles and faster speeds, but it will usually be better to limit approach speeds if possible.

Depending on their positioning they can also be suitable car bomb protection structures.
