An elongated structural article, having a continuous profile extrusion with spaced apart layers defining a portion of a cavity filed filled with thermoplastic pre-expanded beads expanded with steam in-situ causing the beads to securely bond together and to the profile extrusion. The article is cut to a length forming ends having an exposed foam core. A system for manufacturing the article is also disclosed having a profile extrusion die for forming an axially profile defining a wall surrounding a cavity, a tubular shaping mold located axially downstream ...
1. A system for forming an elongated structural article, comprising: a profile extrusion die for continuously forming a at least one axially extending profile defining at least a portion of a wall surrounding a cavity;an elongate tubular shaping mold located axially downstream of the profile extrusion die, and sized to receive and support a length of the at least one axially extending profile as it continuously passes there through;a spider located in an inlet end of the shaping mold within the profile cavity, to support the profile extrusion as it passe...
