ABSTRACT:
An improved I beam construction for longitudinal I beams preferably as used n trailer frames. The I beam is comprised of a top flange, a bottom flange, a vertical web wall interconnecting the top and bottom flanges along their centerlines in a customary manner, for a substantial part of its length, with the novel aspect including a portion of the vertical web wall offset laterally toward the outer side edges of the top and bottom flanges so that said offset wall portion is essentially flush with those said edges. The purpose of this offsetting is to provide more advantageous horizontal and vertical mounting surfaces for saddle mount capability and attachment of a trailer's wheel suspension assembly, which construction is found to be stronger than can otherwise be fabricated.
