Abstract: A vehicle parking structure is disclosed which is comprised of prefabricated, modular components for portability. At the parking location, a steel framework is erected with a grid of support beams which form a plurality of bays. Each bay mounts a metal deck panel which is formed of a deck structure having an undulating cross-section, the top of which carries a flat rigid plate. The deck structure and plate provide a combined moment of resistance sufficient to support the weight of vehicles parked on top of the deck panels. Layers of elastomeric materials are applied over the deck panels for providing a waterproof, non-skid, wear resistant contact surface for the vehicles.
