The Western Pipe and Steel Company (WPS) was an American manufacturing company that is best remembered today for its construction of ships for the Maritime Commission in World War II. It also built ships for the U.S. Shipping Board in World War I and took part in the construction of the giant Grand Coulee Dam project in the 1930s.

The Joshua Hendy Iron Works was an American engineering company that existed from the 1850s to the late 1940s. It was at one time a world leader in mining technology and its equipment was used in constructing the Panama Canal, amongst other major projects. The company went on to serve many different markets during the course of its existence, but is perhaps best remembered today for its contribution to the American shipbuilding industry during World War II.
