Traffic lights: Grolleau’s expertise
Official supplier of the Ville de Paris, Grolleau is a genuine expert in the production of traffic lights. More than 50 years of experience in urban infrastructure taught us to pay great attention to details and to rely on the expertise necessary for this sector. In order to meet our clients expectations as accurately as possible, Grolleau relies on its key asset: high standards of quality. Grolleau became in April 2010 the first EC certified company for all traffic lights equipment. Today, in partnership with light sources developers, Grolleau still is the one and only French company which has the highest qualification level in order to meet such requirements; it is precisely this expertise which we are committed to provide daily to our customers.
