Allied Tube is the leading supplier of galvanized and commercial quality tubing to both manufacturers and metal distributors in many commercial and industrial markets.

Our signature Flo-Coat galvanizing process produces superior corrosion resistance by utilizing a triple-layer of protection. First 99.99% pure zinc is applied, followed by a conversion coating. Finishing the process is a clear organic topcoat that seals in the protection and produces a smooth shiny appearance. This galvanizing process is performed on the mill to produce a finished product that does not require secondary operations such as batch hot-dip galvanizing. Allied Tube has successfully employed these techniques to transform industry and product standards.

The Allied Tube product portfolio has grown substantially since our inception, benefitting customers with a growing number of tubing and roll form products. We are always dedicated to providing the same high-quality workmanship and customer dedication that you have come to expect from our organization.
