Over 90 Years of Engineering Excellence

Celebrating a proud history of customer satisfaction, WES-CO Industries started out by providing applied engineering and fabrication of a significant variety of sheet metal and steel products. Operating throughout Northern California, WES-CO has delivered services to alumina production, power plants, foundries, wood processing and paper mills, chemical and processing plants, food and glass processors, semiconductor, and many other manufacturing and process industries.

Founded in 1923 as Wes-Co Blower and Pipe Company to service the burgeoning cotton and paper mill industry, the firm quickly established a reputation and culture for value and innovative solutions.  Since the beginning, we have prided ourselves on commitment to client relations – a winning strategy that keeps us in the running for over ninety years serving the manufacturing industry. Following close on the heels of technological progress in focus industries, WES-CO is a California company through-and-through, with its entrepreneurial spirit and commitment to solving challenging problems.

As a result of our problem-solving approach, we have built expertise in a broad spectrum of industries, completing industrial projects, and maintaining an active consulting presence, first in the United States, and then throughout the EMEA and Asia region. The WES-CO team has seen and done it all, with additional international experience in industrial general contracting, construction, and efficient project management. Our Industrial Air Filtration and Material Handling systems continue to operate effectively decades into their lifetime.
