Up until recently, the biggest steel H-Pile section you could get was an HP14 weighing up to 177 lb/ft. But ENR reports that manufacturers are now rolling steel H-Piles in 16 and 18 inch depths. The HP16 sections range from 88 to 183 lb/ft and the HP18 are available in 135 to 204 lb/ft. These new sections open up a range of possibilities for deep foundations, shoring systems and excavation bracing. The American Institute of Steel Construction listed these products in their 2010 manual and they have also been approved by ASTM. They can be found in the product literature of Nucor-Yamato Steel.
