Crash barriers


Restraint systems are mainly placed along the road or in the central reservation of a road in order to guide errant vehicles. They can be made of steel, prefabricated concrete or in-situ concrete.

Execution certification can be applied by a contractor or executor of the relevant execution.

Applying for a certificate can be done digitally, via our website. Here you will find all the AFD forms with which the application can be done.
