B-C-D Metal Products, Inc. is small woman owned aerospace manufacturing company located at 205 Maplewood St, Malden, Massachusetts, United States. Established in 1935 as a blacksmith shop, a major change in the company's direction came in 1953 when the company incorporated. Ralph Carlson became President, and his vision took B-C-D from wrought-iron works to a supplier to the aerospace industry. The company began modern production by manufacturing small brackets, then gradually added precision tube forming and assembly to its manufacturing capabilities.
