More than 55 years ago, Allied Tube & Conduit® developed a one-of-a-kind technique to run welded tubing through molten zinc, while still online. The resulting process, Flo-Coat®, revolutionized the industry and provided users of tubing with a product that literally changed their businesses.

In the years to come, new and different Allied products would revolutionize over 70 different marketplaces. We continue to search for groundbreaking new solutions, and embody the entrepreneurial spirit that started this company. Take a moment to learn more about the Allied Tube of today as well about The Allied Advantage.

With more than 55 years of manufacturing quality products for numerous industries, Allied has proven itself a market leader in the mechanical tubing, fire sprinkler pipe, and electrical conduit markets. But, despite any level of success, Allied has never overlooked the fact that it all began with a simple, round metal tube and the process that shapes it.

Today, Chicago (Harvey, IL) is the corporate headquarters for Allied Tube & Conduit® and Atkore International®.
