Flo-Coat Galvanized Steel Tubing

Flo-Coat Galvanized Steel Tubing

Flo-Coat tube galvanized steel is the original in-line galvanized product. It is manufactured using the advanced processing technique of in-line galvanizing first introduced by Allied in 1959.

Over the years our Flo-Coat steel tubing product has benefited from continuous advances in technologies and processes. Flo-coat tube provides advanced levels of corrosion protection while having the ability to be painted or powder coated for aesthetic purposes with little advance preparation. In addition to its longevity, Allied's cold forming process delivers higher strength levels than other competitive tubing products. Our galvanized steel tube product typically carries a minimum 50ksi yield and 55ksi tensile strength for 15 gauge and heavier products.

Advanced Corrosion Protection

Allied's signature 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.

Stronger Than Your Average Steel Tube

We guarantee a minimum 50 ksi yield and 55 ksi tensile on many of our products with the ability to achieve higher properties with different steel chemistry. Compared with many alternatives that demonstrate a 30 ksi yield, Gatorshield demonstrates the unique ability to offer same strength in a lighter weight tube - up to 33% stronger!

Fabricate Without Flaking

Flo-Coat tube is capable of being fabricated using several different methods including hole punching, cutting, flattening, bending 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.

You Can Weld Galvanized

Due to its 99% pure zinc coating; Flo-Coat can be easily welded. Contrary to popular belief, all galvanized products do not perform the same with regards to welding suitability. Weld performance is an important feature of Allied's product line and one that has made it a success in several marketplaces for more than 55 years.

Eliminate Scrap Drops

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