Prosec 90 is a hybrid steel and concrete barrier system. The system consists of a metal frame and truss rods. These rods serve the further purpose of reinforcing the concrete. The benefit of the system is that it has high containment levels but a narrow width, allowing for deployment in areas where there is minimal space to accommodate a barrier. Containment level is rated at H1-H2, dependent on the type of anchoring deployed, while the Working width is W2 or W3.
