HP16x88 – HP Shapes - American wide flange bearing piles

HP16x88 is 15.3 in (389 mm) deep with a 15.7 in (399 mm) wide flange, and weighs 88 lb/ft (131.0 kg/m).

HP shapes are wide-flange sections purpose-built for deep foundation piling. Unlike a W shape, an HP shape has flange and web thicknesses that are equal or very close to equal — a proportion specifically chosen so the section can withstand the pounding of pile-driving without local buckling or damage to the thinner web. Once driven, HP piles carry structural loads down through weak or unstable soil to a competent bearing layer or bedrock, making them a standard choice for foundations under buildings, bridges, and marine and waterfront structures where shallow foundations aren't an option.
