Metal storage sheds, a great post
The initial Quonset huts design included arched steel rib members constructed in a T design and supported by wooden purlins. Design flaws soon became evident as the military began using Quonset huts for more than just troop housing and equipment storage. These uses included showers, latrines, dental offices, bakeries and isolation wards, but the huts needed special layouts to accommodate these additional uses and related equipment. The military modified the Quonset hut design to include vertical side walls supporting an arched roof; this layout provided much more usable space. With no beams or trusses, and 100 percent usable space, the Quonset huts of today serve many purposes.
