Tubing Information:
THE FLO-COAT PROCESS
Allied's patented Flo-Coat process is the superior method of galvanizing steel tubing. The process begins with flat strip steel, which is then cold-formed and either electric-resistance or induction welded. After welding , the tube receives a triple layer of protection - zinc, conversion coating, and a clear polymer topcoat - all applied in-line to assure a uniform coating. The result is a smooth, shiny end product appearance that is unmatched in terms of strength and durability.
Steel Coil
- Allied uses ASTM-A500 Grade A-1008 and 1010 carbon steel; Grade B-1010 through 1022 carbon steel/15 gauge and heavier; Grade C-1015 through 1022 carbon steel/15 gauge and heavier. Please inquire about our ability to meet ASTM-A513 and other ASTM specifications.
Strip Cleaning
- Although Allied uses either CR or HRPO, depending on the gauge, the slit coil receives a further pickling treatment before it enters the roll forme
Roll Forming
- The steel strip is cold-formed into a tube, a process that adds to a higher final yield strength. Allied has the ability to manufacture round tube in sizes from 0.500" to 5.000"; Allied can also manufacture square tubing in sizes from 0.625" to 4.00"; corresponding rectangles and flat-sided ovals are also available.
Welding
- Allied uses an ERW process utilizing an induction welder or a high-frequency welder. Laser imaging of the weld area ensures quality welds.
Interior Corrosion Resistant Coating
- The tube is welded prior to the application of coatings; thus the weld area is as protected from corrosion as the rest of the tube body. This achieved by using a long lance to coat the interior of the tube after welding.
Tube Heating
- In order for the zinc to adhere to the tubing without any additives, the tube is heated to about 1000 degrees Fahrenheit prior to entering the molten zinc pot.
Hot-Dipped Zinc Coating
- Allied's zinc coating contains the lowest lead content achievable (99.99% pure zinc).
Cooling
- The cold forming and quenching process allows Allied's tubing to achieve a yield strength as high as 50,000 psi, considerably larger than the typical yield strength of Schedule 40 pipe (35,000 psi).
Conversion Coating
- Flo-Coat tubing exhibits greater corrosion resistance because of the synergism created between the coatings; the conversion coating passivates the zinc to slow down the white rust growth process.
Clear Organic Coating
- The clear third coating "seals in" the protection and acts as a primer for painting or powder-coating. Extensive precleaning is unnecessary, and excellent adhesion is achieved, even at high baking temperatures.
Coating Cure
- The third coat is cured at this stage - even at speeds of 500+ feet per minute.
Tube Cut to Length
- Allied will cut tube off the mill for length 60" or longer. Shorter sizes can be cur off-line. Allied also has the ability to de-dimple tubing in-line on specific tube mills. All tubing can be de-dimpled off-line. Allied also has the ability to swage tubing on-line and of course, off-line.

Flo-Coat® Tubing
Our signature Flo-Coat® process produces galvanized tube and pipe considered the "Industry Standard" in each of our core markets. Allied's success is due in part to the patented Flo-Coat® process that revolutionized the steel tube industry over 35 years ago. This process has been continuously improved upon, and is just as
unique today.
The triple-coat corrosion protection provided by Allied's in-line manufacturing processes has never been equaled. This triple layer protection (zinc, conversion coating and clear organic topcoat) provides a smooth, shiny product appearance that is unmatched in terms of strength and durability.

What is Gatorshield®?
 |
Allied's Mechanical Tube Division is the world's leading producer of galvanized electric resistance welded steel tubing. Gatorshield coated steel tubing is considered the standard of excellence in farmstead applications.
|
Gatorshield is our patented triple layer Flo-Coat® rust and corrosion resistant product protection that has demonstrated to be the best over the long haul versus all competitive product offerings.
When rust and corrosion protection is needed - Gatorshield is "Gator Tough". In addition, our zinc interior coating provides the inside of the tube with maximum corrosion and rust protection. Inside and out - Gatorshield is the best - and has been the best product choice for over 30 years.
How Does Gatorshield Perform vs. Schedule 40 Pipe?
| Allied's 50/55® significantly outperforms galvanized Schedule 40 pipe, gauge for gauge, in every way and weighs at least 31% less (OD/OD) in popular pipe sizes. Allied guarantees minimum yield strength of 50,000 psi / 55,000 psi tensile strength (fracture point). Yet the test results show that Allied's 50/55® with Gatorshield® yield point was 17% greater than the guaranteed minimum. The galvanized Schedule 40 pipe, however, fractured at 56,200 psi pulling force. |

How does Gatorshield compare with the competition in terms of rust and corrosion protection?
| OD and ID corrosion resistance is monitored on an ongoing basis
using salt spray testing. Random samples are prepared and exposed
to 5% salt fog at 95°F. These samples are examined at regular
intervals until a pre-determined end point is reached. Typical
end points are the first signs of white rust and first signs of
red rust. |
