Steel aircraft hangar, a quick primer
From its application as military shelters, many other contractors began developing their own versions of the Quonset hut for other uses. The basic structure has undergone several redesigns and the major one occurred in 1943 when the manufacturing unit at Quonset Point was reestablished as part of the Stran Steel Division of the Great Lakes Steel Corporation. The variant of the Quonset huts thus developed had a more elongated design and applied the full arch corrugated pipes that was part of the intial model. Versions of the Quonset hut model were manufactured to meet specific requirements, a prime example being the Pacific huts, which helped even conserve metal reserves. Some designs of Quonset huts were even constructed as air raid cover.
