Abstract

The disclosure relates to an in-line process for producing a coating by galvanising an elongate member with a coating that comprises zinc and aluminium. The aluminium is in a range of 5-20 wt%. The process comprises cleaning and applying a flux that is free from alkali metal to an external surface of the member, drying the flux on the member and pre-heating the member and passing the pre-heated member through a bath comprising the coating of zinc and aluminium and them removing the coated member. The flux may comprise acidic zinc chloride and ammonium chloride. The disclosure also relates to a bath suitable for an in-line coating process and an air wiper suitable for an in-line coating process.
