In 1951, Millard Towers (formerly Millard Electric), working with the Canadian Department of National Defence and the Department of Transport, developed frangible airport approach lighting towers. Frangibility is a unique technology that allows a tower to collapse on accidental impact by an aircraft, but is still strong enough to endure heavy winds, ice loading, and jet blasts while providing minimal deflection. The towers were also designed to be lightweight and sectional making transportation and installation easy.
Soon after the development of this technology, Millard began supplying defence related applications: civil aviation installations, navigational aids, security towers and environmental monitoring structures. Performance critical structures were engineered to meet the most demanding environmental and logistical applications. Many of these units have been in maintenance free operation in the Canadian Arctic for over fifty years!
Today, Millard manufactures specially engineered towers for aeronautical, navigational, defence, and meteorological applications. Millard's main products include airport approach lighting masts, Instrument Landing System (ILS) support structures, meteorological towers, Non-Directional Beacon (NDB) towers, and navigational aids.
