Abstract: The present invention is a synthetic-core construction panel having a polyurethane core encased by a metal grid. The grid system comprises a first series of metal bars disposed in parallel to each other, equally spaced apart around the circumference of the core; a second series of metal bars, disposed in parallel to each other and perpendicularly to the first series of metal bars, equally spaced apart, are also disposed around the circumference of the core; and a plurality of diagonal cross-member reinforcements welded at their edges to each connecting point between the first series of metal bars and the second series of metal bars. The metal grid serves as a surface accepting masonry/plaster as a finish for the panel after installation. An apparatus for making the synthetic core construction panels is also described and claimed.

Abstract: The present invention is a synthetic-core construction panel and an apparatus for making same. The panels themselves have a polyurethane core encased by a metal grid.
