No factors of safety have been applied to these figures. Project engineers are responsible for determining and applying the factors of safety they deem acceptable to the values above. We can supply pilings with custom wall thicknesses and diameters and can also engineer pilings to meet specific engineering requirements.
Note: Manufacturing is done to English units, the following table is converted from the English specifications table.
