Founded by a Korean War Veteran, Wesinco began as a casework manufacturer in the Southeastern United States in the early 1960s, initially focusing on schools and hospitals. By the 1980s, the company shifted its focus to laboratory casework, completing projects for pharmaceutical labs like Burroughes, Wellcome and Pfzer, as well as petroleum laboratories for Sonoco and BP.

In the early 2010s, our casework transitioned to solely steel fabrication. Over the last 15 years, over casework has evolved into lean, modular designs that allows for maximum flexibility, supporting the biotech loom in San Diego, San Francisco, and Boston. Headquartered centrally in the Chicago area, we are positioned to serve the entire continental US as efficiently and expeditiously as possible.
