H-Piles are dimensionally square structural beams that are driven in the ground for deep foundation applications. Most soils at or near surface do not have the mechanical properties to support large buildings. As you go deeper into the earth’s geology, there are layers (bearing strata) capable of doing so. H-Piles are manufactured and designed to transfer structural loads to these good bearing soils.
H-Piles are also used in conjunction with sheet piles to add lateral stiffness and bending resistance where loads exceed the capacity of sheet piles alone.
Structural shapes distributed by L.B. Foster Piling are rolled to conform to the latest ASTM Structural Steel Specification. Rolling and cutting tolerances shown in this catalog are in conformance with ASTM A6/A6M.
Weights of rolled sections are computed on the basis that one cubic foot of steel weighs 490 lbs. Weights have been calculated on theoretical dimensions and rounded to the nearest pound.
Rolling shapes involves factors such as roll wear, subsequent roll dressing, and temperature variations, which cause actual dimensions to vary slightly from the published dimensions, within the permissible ASTM tolerances. The radii of fillets and rounded edges are likely to change during the rolling process due to roll wear. The listed dimensions of k and k1 generally allow for these wear variations.
Derived design property values have been calculated from the theoretical dimensions, and generally rounded to three significant figures. Fillets have been included in computations of weights and properties.
