The 'Type F' is used for the larger signs and comprises 400mm prefabricated aluminium triangle prisms enabling us to produce variable areas with lengths of up to 17000mm. The signs supplied by Altaroute Ltd. for installation on both posts and gantries vary considerably in size. They can range from approx. 600mm wide x 600mm high to 22,000mm wide x 4700 high and virtually any combination of sizes in between. The longest 3-sided prism we manufacture in a single span is 8,500mm long, however, by introducing a centre support bearing enables us to produce prisms up to 17000mm in length all driven by a single 230VAC motor enabling the sign to cover a 4-lane carriageway.
All Fixed Text Message Signs supplied by Altaroute Ltd. have a design life of a minimum 15 years with minimal maintenance.
