A post that comprises at least one elongate flange with one or more spaced apertures therethrough is disclosed. A given one of the apertures is located and configured to be elongate, whereby a longitudinal axis of the given aperture is generally parallel to or aligned with an elongate axis of the flange. Configuration of the aperture, as presently disclosed, has surprisingly been shown to assist with the prevention of failure of the post at the aperture when a bending moment is applied to the post in a first instance. The post may be employed in applications such as fencing, demarcation, signage, retention, barricades etc.
