Waterloo Industries – A heritage of quality
Waterloo’s tradition of quality and innovation spans over 90 years.
The company began as the Waterloo Valve Spring Compressor Company, founded by Croatian immigrant Nicholas Sulentic in Waterloo, Iowa in 1922. The company's valve spring compressor was an innovative automotive tool, but it was an awkward size. Soon, the company designed a metal tool box to carry samples of the tool on sales calls. The box drew so much interest that the company began manufacturing tool boxes in 1938. Soon the company was manufacturing tool boxes of all kinds and sizes.
World War II generated more business and led the company to grow to over 100 employees. A new manufacturing plant opened in 1946 in Waterloo, IA. By 1957, the company had 225 employees and ceased manufacturing valve spring compressors. Metal tool boxes became the sole source of revenue.
The name of the company was changed in 1967 to Waterloo Industries, Inc. Business grew rapidly and led to the construction of new manufacturing facilities. Waterloo currently manufacturers at our state-of-the-art facility in Sedalia, Missouri.
