Below is a list of Aluminum Rods manufacturers from Logansport, Indiana. Aluminum rods are cylindrical aluminum shapes. As opposed to aluminum tubes and pipes, which are hollow, aluminum rods are solid. They are used in the construction industry as shafts, railings, stakes and tines, as well as in many other industries for many other purposes. These simple shapes are produced from heated aluminum billets by extrusion under high pressure through a die that has a round shape.
