About Conyngham Sales Company
In 1946, Conyngham Sales Company was founded in Conyngham, Pennsylvania, by Henry Dryfoos III. The company was formed to represent the Great Lakes Steel Corporation in the sale and installation of Quonset Huts in the Central Pennsylvania area. When Great Lakes became Stran-Steel Corporation in the early 1950s, they stopped manufacturing Quonsets shortly after. In 1952, Mr. Dryfoos moved the company to the Washington, DC, metropolitan area, where we began concentrating on light gage steel framing and pre-engineered steel buildings.
In 1959, Henry Dryfoos IV joined the family business, and Conyngham Sales went on to become one of the leaders in the sale of steel framing and pre-engineered steel buildings.
When Stran-Steel discontinued their light gage steel framing line in 1967, pre-engineered steel buildings became their sole product to be manufactured and sold. At that time, we expanded our operation from strictly sales and installation to performing the entire general contract, while Stran-Steel was the principal product involved.
In 1989, Stran-Steel Buildings, which had been purchased by Amca International Corporation in 1979, was merged with a sister company, Varco Pruden Buildings, and became VP Buildings, Inc., which it remains today. In 2008, VP buildings was purchased by Bluescope Buildings of North America, Inc., and their name has remained the same. At the present time, we are their oldest builder, and have been representing Stran-Steel and VP ever since.
