FLAME SPRAY GALVANISING
Flame spray galvanising is the surface protection of component parts either in itself or as pre-treatment for further coating.
In addition to hot-galvanising and chemical galvanising flame spray galvanising is a good way to protect steel surfaces against corrosion. The application of flame spray galvanising is mainly limited to component parts, which may not be coated in other processes for technical reasons. For example, in the case of wrought-iron work the galvanisation using hot-galvanising is often not desirable as the liquid zinc used would affect the wrought-iron work too much. Another advantage of flame spray galvanising is the possibility to apply lacquer layers immediately onto the component parts and to achieve durable, good lacquer bonding. Think of the hot-galvanised railings, where colour is regularly peeled off and must be renewed.
Before flame spray galvanising the component parts must be blasted. Then zinc is applied onto the blasted surface in the thermal spraying process, wire flame spraying or arc spraying. The surface warming and the resulting shape distortion does not occur, or only occurs minimally, in the process of flame spray galvanising.
Flame spray galvanising is a production process, which is certifiable according to the federal immission protection act and the relevant ordinances.
We use wire flame spraying as well as arc spraying with zinc. To do this, we have a spraying stand, which may be approached with rail lorries. Our plant is fully certified.
