Ventilated facades are becoming popular not only in building construction but also in infrastructure construction. More and more of this type of facade can be found in road and railway tunnels, underground passages, metro stations and overpasses. BSP System substructure systems are perfect on this type of communication facilities. This is confirmed by research conducted at the Road and Bridge Research Institute, resulting in the issuance of the National Technical Assessment for BSP System products for use in transport infrastructure engineering. These products meet increased anti-corrosion requirements, corresponding to the C5 environment category, established in closed communication facilities.
