  • How Does the GatorShield Coated Tube Perform in Terms of Fabrication Properties Versus Competitive Product Offerings?
    GatorShield ductile steel tubing withstands the tube bending and forming needed for fabricating outdoor structures

    A comparison of the requirements for fabricating outdoor structures of GatorShield and aluminum reveal major advantages for GatorShield:

    GatorShield ductile steel tubing with stands the bending and forming required for custom awning designs, recreational equipment, etc.. Common tempers of aluminum, however, continue to age- harden while in storage, and can break during any fabrication process, causing costly scrap losses.

    Aluminum loses approximately 50% of its strength in the weld area, which could cause post- installation failure if welds are not located in low stress areas of the structure during its design. In addition, welding of aluminum, or using aluminum electrodes, which contain magnesium, can result in unsightly black deposits.

    Steel structures require significantly fewer welds as indicated in the table below and the engineering drawings to the left. The result is lower welding labor costs for GatorShield structures. Welding GatorShield also requires less expensive equipment and materials. And, unlike aluminum, GatorShield can be easily welded in the field.

    GatorShield steel tubing is easily and less expensively painted or powder coated than aluminum, offering variety in color, texture, and sheen to enhance design possibilities and aesthetic appeal. Because GatorShield's third coat has the same paint chemistry and surface consistency as costly primers, finish adhesion is excellent, providing a long lasting, attractive appearance.

  • What About Painting of Powder Coating Over GatorShield® Triple Coat Finish?
    painting of powder coating over GatorShield steel tubes

    It's easy to paint or powder coat over our 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.

    Our galvanized steel tube coating will also withstand in-line chemical cleaning baths and rinses. At the same time, our coatings will not damage or contaminate any part of your cleaning systems.

    Allied's 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 thermostat 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 our clear topcoat. If the paint/powder coating you are using does not fall into one of the above categories, or you have any questions, please contact Allied's Mechanical Tube Division for more specific information.

  • What About Welding GatorShield®?
    GatorShield and welding galvanized tubing

    GatorShield's zinc coated finish welds quickly and easily under working conditions and utilizing prescribed welding procedures. Allied's 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 an absolute minimum.

    When welding ant 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 Allied's custom touch-up paint, which has been specifically developed for this purpose, and is available directly from Allied.

    If you would like more in-depth information on welding galvanized steel tubing, or the various methods of restoring corrosion resistance to weld areas, please contact your sales representative for a copy of Allied's Welding & Painting Guidelines.

  • What About Treading GatorShield?
    Threading galvanized steel tubing with GatorShield

    On 15 gauge and heavier products, in all popular pipe sizes, standard threading procedures apply.

    With lighter-gauge tubing, the threading tolerances must be proportionately modified. For detailed threading procedures, please see Allied's Galvanized Steel Tubing Threading Guidelines. They are available from your local sales representative, or call the Mechanical Tube Division at (800) 882-5543.

  • 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 50,000psi...55,000 tensile strength (fracture point). Yet the test results show that Allied's 50/50® 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.
