Abstract

In one aspect, the present invention provides a load-bearing structure with a novel interlocking edge. Also provided is a method of making a load-bearing structure having an overlapping edge, in which structural members are combined so that a stepped-down lip of one structural member covers a peripheral edge of another member. Also provided is a load-bearing structure having cellular structure and which is useful with or without an overlapping edge. In addition, there is provided a molding method for making cellular, load-bearing structures.
