A Quonset hut /ˈkwɒnsɪt/ is a lightweight prefabricated structure of corrugated galvanized steel with a semi-circular cross-section. The design was developed in the United States based on the Nissen hut introduced by the British during World War I. 170,000 Quonset huts were manufactured during World War II, and the military sold its surplus huts to the public after the war. The name comes from the site of their first deployment at Quonset Point at the Davisville Naval Construction Battalion Center in Davisville, Rhode Island.
