Abstract
A lightweight panel is provided that may be used as a gate, a fence section, or the base of a temporary carport. The panel may be selectively made more massive, and includes a peripheral structure comprised of hollow plastic extrusions having corresponding solid extrusions disposed therein while leaving sufficient space to permit a liquid to be interposed within the hollow plastic extrusions when desired.
