GATORSHIELD
TUBING

1 What is Gatorshield®?
And why is it Gator Tough?
2 What Else Should I Know About Gatorshield®?
Gatorshield is a patented triple layer Flo-Coat® rust and
corrosion resistant product protection which has shown
itself 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, the 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.

• It’s available in:
   • round, square and rectangular shapes
   • a 1/2" to 5" O.D. size range
   • a .028 to .250 wall thickness (gauge) range
• It delivers a smooth, shiny appearance.
• It can be easily fabricated with no deformation or
   flaking of the base material.
• It can be produced in whatever length is needed to
   meet your specific requirements.

Gatorshield is a patented triple layer Flo-Coat rust and corrosion resistant product protection which has shown itself to tbe the best over the long haul verses all competitive product offerings. Gatorshield Tubing is available in round, square and rectangular shapes in a  1/2" to 5" outer diameter size range.
Gatershield coated steel tubing is considered the standard of excellence in many industrial end-use applications.

6 What About Painting of Powder Coating Over Gatorshield® Triple Coat Finish?
It's easy to paint or powder coat over the galvanized steel tubing with almost all powder or liquid paints working well over the clear topcoat. It’s easy to paint or powder coat over the galvanized steel tubing. Simple surface cleaning of the tube is required due to normal transportation and storage related accumulated soils. Merely wipe off such soils with a mild cleaning solution. The galvanized steel tube coatings will also withstand in-line chemical cleaning baths and rinses. At the same time, these coatings will not damage or contaminate any part of a cleaning system. These galvanized tube products are protected by a clear, organic top coating which provides excellent adhesion properties to most thermo-set powder coatings, as well as to the following air dry and bake topcoats:
• High bake thermoset acrylic
• High bake alkyd
• High bake polyester
• Two-part urethane or epoxy
• Solvent-based paints for metals
• Solvent-based paints for wood
• Solvent-based high-solids paints
• Oil-based paints
• Paints for car bodies or appliances
As you can see, almost all powder or liquid paints will work well over the clear topcoat. If the paint or powder coating you are using does not fall into one of the above categories, or you have any questions, please contact us.
7 What About Welding Gatorshield®? 8 What About Threading Gatorshield®?
Gatorshield’s zinc coated finish welds quickly and easily under normal working conditions and using prescribed
welding procedures. The galvanizing process utilizes a
99.99% pure zinc alloy with significantly less harmful
lead content than generally encountered with
pregalvanized tube and hot-dipped Schedule 40
products. This means that the lead oxide fumes
generated during welding are kept to a minimum.
On 15 gauge and heavier
products, in all popular pipe
sizes, standard threading
procedures apply.
Standard threading procedures apply for all 15 gua
With lighter-gauge tubing,
the threading tolerances
must be proportionately
modified. For detailed
threading procedures,
please call us for the
Galvanized Steel Tubing
Threading Guidelines.
When welding any galvanized tubing, it is important to
restore the corrosion resistance of the weld zone to that
of the surrounding tube area. This is easily accomplished
by using a custom touch-up paint, which has been designed for this purpose, and is available from Allied.
For more in-depth information on welding galvanized
steel tubing, or the various methods of restoring
corrosion resistance to weld areas, please contact us for
a copy of Welding & Painting Guidelines.
10 How Does Gatorshield® Perform vs.
Schedule 40 Pipe?
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.

Guaranteed is a minimum yield strength of 50,000 psi - 55,000 tensile strength (fracture point). Yet the test results
show that 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. And when compared with aluminum pipe, 50/55's
superior strength characteristics are even more dramatic, with an average 60% greater load carrying capacity in
tension. Plus, Gatorshield offers the added benefits of easier, more reliable welding, increased structural rigidity,
greater impact resistance and substantially lower material cost than with aluminum Schedule 40 pipe.
