Abstract:
A hollow core board product has a core and a relatively thin skin is attached to either side of the core, the skin having a peripheral shape conforming to the desired shape of the product. In one embodiment, the core is a grid having a preselected number of elongated linear grid members, the members being selected and configured to have a relatively high compression resistance, and being interlocked in a crossing pattern to form the grid, such that the number of grid members utilized and their spacing will determine a load bearing capacity of the hollow core board product. In another embodiment, at least one solid block member is inserted at a desired location in the core and positioned so as to closely abut at least one of the skins. A frame may also be provided if desired.
