Out of my head on the topic of commercial steel buildings
Because of their simple yet strong iron arc structure, Quonset huts offered a very efficient use of interior space. The flexibility and simplicity of the huts allowed the military to have immediate solid structures for medical facilities, vehicle repair shops, barracks and storage. The metal structures were definitely an improvement over the wooden foundation tent structures that had served those functions. The Quonset huts produced during the war were sold to the general populations for about $1000 each after the war. Since then, Quonset huts not produced by the military have been manufactured and utilized for a plethora of commercial and residential uses.
