A structural helical pile having an elongate shaft member defining a longitudinal
axis. The structural helical pile also comprises a radially extending, generally
helical load bearing member integral with the shaft member and projecting outwardly
from the longitudinal axis of the shaft member. The helical load bearing member
has a leading edge and a trailing edge. The respective leading and trailing edges
intersect the shaft member in spaced relationship along the longitudinal length
of the shaft member. The helical load bearing member further comprises at least
one rib integrally formed therein. In this aspect, each rib extends outwardly from
the longitudinal axis of the shaft member and has a substantially uniform cross-sectional thickness.
