Aluminum poles are made from 6061 or 6063, aluminum alloy seamless extruded tubes. They are heat treated after welding to produce a T6 temper. Aluminum poles are lightweight, low maintenance and corrosion-resistant. They are available for both anchor base and direct burial installation.oncrete Poles. Concrete poles are very utilitarian and are used in areas where high winds and corrosive atmospheres are a concern. Concrete poles are ideal for applications where limited deflection is required e.g. highway cameras, parking lot security cameras, sports lighting, etc.
