In-line coating is commonly carried out in ceramic or metallic baths.
Our special metal alloy vessel has shown its strength and long lifetime. Easy access to the wire field and limited amount of zinc aluminium alloy in the bath are the two attractive parameters of this solution. When the aluminium content is going ahead of the concentration applied in Galfan®, ceramic baths are taking over. Both top heated and immersed thermal plungers have shown their reliability for such alloys.
Nitrogen wiping technology is applied successfully for those alloys. As sometimes space is missing to put a new zinc aluminium coating bath, FIB has developed a specific “off-line” technology to apply Galfan® coating on pre-galvanized wires.
