Willoughby Industries takes pride that, with very few exceptions, we produce all aspects of all of our products. We start with stainless steel, resin, and plastics to craft the finest commercial/institutional plumbing products in the industry. Our facilities include full CNC machining centers, manual and robotic welding departments, electronics manufacturing and assembly areas, laser and plasma cutting, press brakes and draw presses, valve assembly stations, and a state-of-the-art solid surface facility comprised of mixing, pouring, molding, and finishing areas. The Willoughby manufacturing facility is centrally located at 5105 W. 78th Street, Indianapolis, IN 46268. Indianapolis has been our home since our first steel product was sold in 1947. As a family owned business, Willoughby improves local economic growth by employing an Indiana workforce. Our employees take pride in their work, and the quality of our product reflects that positive attitude.
