An exhibit or structural system designed to be fully disassembled into flat-pack or compact components for efficient shipping and storage, then reassembled on site without permanent fasteners or adhesives. Knock-down construction is a fundamental principle of reusable trade show exhibit design, allowing large structures to ship in a fraction of their assembled volume. KD systems rely on precision fabrication, standardized hardware, and clear assembly documentation to ensure that repeated installation and dismantle cycles do not compromise structural integrity or finished appearance.
