A Brief History

Steel Plate Fabricators was founded in 1921 as A.J. Russell & Son in an outbuilding of A.J. and Lucinda Russell’s home in the Lonsdale community. Durning the 1940s, their son, Calvin, and his wife, Helen, continued the business and incorporated as Knoxville Sheet Metal Works, Inc. In 1964, their son, David, and his wife, Merle, took over and steered the business from light gauge sheet metal to heavier fabrication. The company started doing business as Steel Plate Fabricators.
In 2007, 4th generation and son, Mike, and his wife, Anna, purchased the company and have continued to honor the core values that were established over 100 years ago. Steel Plate Fabricators is a quality-driven metal fabrication company with experience in certified welding and heavy plate fabrication. Using advanced equipment and proven fabrication methods, SPF delivers dependable solutions for demanding industrial applications.
