The company began in 1914 as Kenosha Boiler and Structural Co. It provided structural steel and weldments to local industry and a variety of steel fabrications in the Midwest.

The company changed its name to Lakeside Steel & Mfg. Co. to better represent the change from pressure vessel and structural steel framing work, to heavier fabrications with plate and miscellaneous structural work the focus going forward.

In 2014, Lakeside Steel & Mfg. Co. celebrated its 100th Anniversary in business here in Kenosha, WI.
