H-piles are beneficial in rigidity, as the continual cross-part which is entrapped in soil among the flanges provides fantastic residence to pullout. Also, H-piles can be used as battered rigidity piles to anchor sheet pile bulkheads. Metal H-piles can perform both of those as compression and pressure piles when uplift because of hydrostatic or wind conditions is often a thought in foundation design.
