Stronger, lighter, more durable. Those are some of the words used to define Allied’s galvanized steel tubing. Add Western grade pure zinc and advanced corrosion fighting coatings to the highest quality materials available and you get a galvanized steel tube product that provides a level of strength and corrosion resistance that is unmatched in the industry. In the years to come, new and different Allied products would revolutionize the construction and OEM marketplaces, as well as countless others. We haven’t stopped innovating since- by adhering to our core belief that by better understanding our customers business, we can better provide groundbreaking new solutions.

Allied Versus the Alternatives

Gatorshield ®  and Flo-Coat ®  deliver excellent results when compared with competing products.

Mechanical Tubing Size Chart 


We guarantee a minimum 50 ksi yield and 55 ksi tensile on many of our products with the ability to achieve even higher properties. Compared to Schedule 40 pipe at 30 ksi, Allied Tube and Conduit’s tubing provides a variety of higher strength alternatives. Please refer to Allied Tube Conduit’s Weight Per Foot Chart for specific specifications.

Allied Tube Conduit’s tubing is adapted for the specific use of your applications. Our tube is produced by specific wall thickness rather than schedule pipe designations. Allied Tube Conduit’s tubing demonstrates that strength is not represented by wall thickness alone, but rather by the appropriate combination of steel grade, yield/tensile properties and our unique processing techniques.

Allied Tube Conduit’s signature in-line galvanizing process exhibits superior corrosion resistance by utilizing a triple layer of protection. First a 99.99% pure SHG zinc coating is applied to the surface, followed by a conversion coating. The process is completed by adding a clear organic topcoat that seals the surface and produces a smooth shiny finished product unique to Allied Tube and Conduit. Exceptional corrosion protection is achieved by the combined performance of our three bonded coatings as compared to a single layer of zinc. Allied Tube Conduit’s tubing is designed to meet critical, long lasting applications, and is ideal for outdoor or high-moisture environments.

Due to its 99.99% pure SHG zinc coating; Allied Tube Conduit’s tubing can be easily welded. Contrary to popular belief, all galvanized products do not perform the same with regards to weldability. Weld performance is an important feature of the Allied Tube Conduit’s tubing product and one that has made it a success in the marketplace for over 50 years.

Allied Tube Conduit’s tubing is also capable of being fabricated using several different methods including hole punching, cutting, flattening, bending, swaging and more without the degradation of the coatings. All of these operations can be performed without cracking, flaking or otherwise damaging the integrity of the coating.

There is nothing standard about our mill cut lengths. We produce the lengths that you require for your applications. Custom mill lengths from Allied Tube Conduit allow you to minimize the scrap generated when having to cut standard lengths of pipe products.
