Galfan^® Lines (Zn- 5% Al Alloy)

The eutectic point mixture of 95% zinc and 5% aluminum forms an alloy that exhibits excellent corrosion resistance by combining the sacrificial characteristics of zinc with the hard and less porous nature of aluminum oxides. The coating is formed in a fine lamella structure with a thin ductile alloy layer against the steel. Coating life can be 2 to 4 times as long as pure zinc coatings of the same mass when subjected to similar corrosive environments. The ductile nature of the Galfan® coating lends itself well to formability and redrawing. Galfan coatings also withstand heat better than zinc and therefore can be welded into mesh without losing corrosion resistance at the weld and also permit higher operating temperatures for ACSR wire.

With eight QED Galfan^® installations on 3 continents, we have gained exceptional equipment experience and significant process knowledge. Our Galfan lines incorporate the latest state-of-the-art technology with Siemens PLC panels, patented combustion systems, mass-flow control and high speed wiping systems.

The double dip process has proven very reliable and successful in making quality Galfan^® wire. With or without heat-treatment the process line usually involves; pickling, fluxing, drying (optional) galvanizing, wiping (pad or N2), pre-Galfan flux (optional) and finally Galfan^® with nitrogen wiping.
