Flo-Coat® is a galvanized steel tube that is produced using the in-line galvanizing process. The Flo-Coat® method employs technologies to triple coat the steel tube with the purest form of western grade zinc, clear conversion coating formula, and clear organic top coating. Flo-Coat® demonstrates synergistic performance of the conversion coating and clear organic top coating in protecting the zinc layer, which is not employed by hot-dip galvanizing.
Because of the substantial retardation of initial white rust formation due to this synergistic performance, Flo-Coat® at a minimum can last for the same period or for a longer period of exposure compared with hot-dip galvanized pipe before they exhibit the same level of corrosion failure.
The inside surface of Flo-Coat® tube is always coated with a true zinc-rich coating bearing 87% – 93% zinc dust loading by weight. The resin in these coatings is formulated with an epoxy-silicone compound that is cured at extremely high temperatures to impart an excellent coating tenacity.
