Abstract: A structural plank assembly formed from: (a) a plurality of structural beams that define an enclosure; (b) a bottom wall; (c) a top wall; and (d) a structural foam filling the enclosure, wherein at least one of the structural beams includes: (i) a top planar member; (ii) a bottom planar member; (iii) a wall member connected to the top and bottom members; (iv) a pair of shelf members; and (v) four angled members, wherein each of the four angled members have sectional knockouts passing therethrough.

Abstract: A foam filled structural plank made from a plurality of structural beams assembled together to form a structure capable of supporting the weight of a building thereon, wherein the plurality of structural beams define an enclosure therebetween and an outer perimeter therearound; and a structural building foam such as having expanded polystyrene foam having a density from 1.5 to 3.0 PFC filling the enclosure.
