What is Flo-Coat and how is it different than batch hot-dip galvanized tubing?
Flo-Coat is a galvanized steel tube that is produced using the in-line galvanizing process. The Flo-Coat method employs technologies to triple coat the steel tube with the purest form of western grade zinc, clear conversion coating formula, and clear organic top coating. Flo-Coat demonstrates synergistic performance of the conversion coating and clear organic top coating in protecting the zinc layer, which is not employed by hot-dip galvanizing.
Because of the substantial retardation of initial white rust formation due to this synergistic performance, Flo-Coat at a minimum can last for the same period or for a longer period of exposure compared with hot-dip galvanized pipe before they exhibit the same level of corrosion failure.
The inside surface of Flo-Coat tube is always coated with a true zinc-rich coating bearing 87% – 93% zinc dust loading by weight. The resin in these coatings is formulated with an epoxy-silicone compound that is cured at extremely high temperatures to impart an excellent coating tenacity.
Lastly, Flo-Coat demonstrates a smooth, uniform coverage of coatings. The irregular, bumpy surface of hot-dip galvanized pipe results in a rough surface.
How does the strength of Allied’s Flo-Coat products compare to competitive products such as pre-galvanized tube and hot-dip galvanized pipe?
Allied’s Flo-Coat products demonstrate excellent strength characteristics, frequently superceding those of competitive products. Most products that are 15 gauge (0.072” nominal) and heavier achieve 50 ksi min. yield and 55 ksi min. tensile. The chart below demonstrates Flo-Coat yield strength on a comparative basis.

What is the difference between Flo-Coat and Gatorshield
Flo-Coat and Gatorshield are manufactured from the same process yet yield different coating weights, benefitting different applications. Flo-Coat is intended for applications that are either indoors or will ultimately receive a final coating of paint or powder coating. Flo-Coat demonstrates our standard coating level of zinc at 0.30 oz./ft.2.
Gatorshield is intended for applications that are either outdoors or are in highly corrosive conditions. Gatorshield demonstrates a greater level of zinc at 0.60 oz./ft.2 for increased corrosion protection.
How many manufacturing facilities are operational for Allied Tube?
We currently have 4 manufacturing facilities, and 2 fabrication facilities:
- Harvey, IL (Headquarters)
- Phoenix, AZ
- Philadelphia, PA
- DePere, WI
- South Holland, IL
- Kokomo, IN
Do you produce anything other than in-line galvanized mechanical tubing?
Yes. We also produce tubing products that are not coated such as HRP&O (Hot rolled pickled and oiled), Cold Rolled (CR), and pre-galvanized substrate.
HR and CR are also available as uncoated with a Qwik-Coat lacquer topcoat (replacing standard RP oils) and optional ID coating. These OD and ID coatings benefit ERW users with added shelf life as well as surface quality for painting or powder coating.
Do you sell less-than-truckload quantities?
Yes. Allied has developed a network of stocking distributors making our product available in less-than-truckload quantities. This network of distributors is strategically located throughout the U.S. and Canada to accommodate your orders. Please visit our Rep Locator for the distributor contact nearest you.
Can I weld in-line galvanized mechanical tube?
Yes. Allied’s tube can be easily welded because we use pure 99.99% Organic zinc grade for our in-line products. Our in-line galvanized tube is applied in a controlled process on the mill achieving a smooth, even coating. This process makes it much easier to weld and reduces the amount of hazardous fume emissions in the welding process compared to hot-dip galvanized.
