Steel Piles

High strength of steel creates it a good material for piles. Steel piles could be within the form of rolled steel H-sections or seamless/welded steel pipes. They could be directly driven within the ground for use as piles. The tubes could be open ended or close ended. In that case of open ended pipes, after that the piles are driven, the earth inside is cleared out through water jetting and filled along with concrete. The closed ended pipes are given along with a shoe to facilitate driving and these are also generally filled along with concrete.

Because of its inherent strength, a steel pile could withstand the huge impact of the pile driving hammers and could penetrate by associative hard strata and boulders. The total length of pile could simply be extended through welding additional piece(s) or shortened through cutting. Steel piles cause little ground displacement and hence, could be driven at close intervals, or near existing buildings. They needs less storage space and could be handled simply as compared to precast RCC piles.

The drawback is the possibility of corrosion and lesser frictional resistance along with reference to transfer of load. These piles are more expensive than other kinds of piles and therefore, they are not used extreme widely. They could be used for extremely heavy loads and for foundations of trestles, bridges etc.
