Abstract

Disclosed herein is a light-gauge, ultra-high strength weathering steel pile for use as a steel foundation in structures such as, for example, solar arrangements. The light-gauge, ultra-high strength weathering steel pile comprises a thickness of 2.5 mm or less that has been cold roll formed into a steel pile having a web and a pair of opposing flanges, each having discontinuities formed therein. The steel pile further comprises a yield strength of between 700 and 1600 MPa, a tensile strength of between 1000 and 2100 MPa, and an elongation of between 1% and 10%.
