Gatorshield® Advantages for Your Greenhouse Structures

Galvanized Greenhouse TubingGreenhouse TubingGreenhouse Steel TubingGreenhouse Galvanized Tubing

Since the industry’s early days, Allied’s Gatorshield® tubing has been the preferred choice for greenhouse and shade structures.  No other tube can offer excellent tensile and yield strengths, combined with unsurpassed corrosion protection, and ease of formability. Gatorshield®’s triple layer of protection can be bent, cut, drilled, and swedged without worry of the galvanization peeling, flaking, or cracking.  We offer a wide range of round and square tubing designed to meet the needs of greenhouse manufacturers such as Hoop Material, Purlins, Ground Stakes, and Bracing Supports.

Superior Strength

Minimum 50,000 psi yield strength and 55,000 psi tensile strength provide the ultimate in structural integrity.

Unsurpassed Corrosion Protection

Our product demonstrates a longer service life because of the synergism created among the three coatings.

  • 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.
  • The inside diameter of our tube is a zinc-rich corrosion-resistant coating applied after the tube is welded, completely covering the interior.
  • Gatorshield® is more resistant to rust than any competitive tube product. The Flo-Coat process makes the difference!
