Four diameters, four gauges and three rates of taper enable the designer to select a Monotube suitable for a wide variety of economical applications. For fully embedded foundation piles the most commonly used diameters are 12 and 14 inches with design loads up to 150 tons, contingent on soil capacity. An unusual advantage of the Monotube pile is the ability to nest a tapered section into an extension to produce a compact bundle. This process reduces shipping and storage volume by as much as 40%.
