Abstract
The plastic structural article includes an elongated tubular shell having opposed end sections, a middle section there between and an interior cavity. The interior cavity has a foam core situated therein. The foam core comprises steam expandable polymer beads which when expanded substantially fill the interior cavity. The bead and shell are of a similar plastic composition enabling the articles to be reground and recycled. An apparatus for forming the articles and an associated method of manufacture are also disclosed.
