ThunderCoat™ Zinc Coated Galvanized Mechanical Tube


When you need a tube that can withstand the elements on its own, ThunderCoat™ is your best choice. We apply a heavier zinc coating in-line to prepare the tube for outdoor applications or any environment that experiences high humidity. Even with a heavier coating, ThunderCoat™ withstands the rigors of your fabrication processes.

Twice the level of 99.99% pure zinc compared to our SURcoat product, ThunderCoat™ is ideal for outdoor applications. Our in-line galvanizing process gives you the benefit of the galvanic protection of a durable zinc layer and then makes it even better with the application of a conversion coating to stop white rust, and a top coat to seal the surface from the elements. While our nearly pure zinc coating is protecting the steel tube beneath it, our top coats are protecting the zinc as well. The weld is completely covered in our process unlike products that must try to repair the weld surface after forming.

The synergistic effects of this coating system are well established and protection well beyond the protection of each of the individual coating layers is achieved. Our highly controlled, uniform OD coating provides protection that can still be easily formed, welded, or assembled while maintaining superior corrosion protection. Our ID is completely sealed, including the weld, with a baked on zinc coating that provides both barrier and galvanic corrosion protection. We leave no bare, uncoated areas where corrosion can start.

ThunderCoat™ from Wheatland Tube helps you to minimize cost associated with superior corrosion protection. We deliver a product to you that is ready to use without the additional cost, handling, and transportation associated with after fabrication corrosion protection methods. Additionally, our coating is easily repaired using cold galvanizing products to restore corrosion protection as a result of welding or other mechanically abrasive processes. Buying in-line galvanized tubing helps get your products out the door faster so that you can be more productive in your business.
