Thermal Spray Galvanising - Anti Corrosion Overview
Thermal spray galvanising, provides a long life coating for up to 40 years and is suitable for all applications up to 420° C. This process is often specified in preference to hot dip galvanising to avoid the risk of distortion.

What is Thermal Spraying ?
Thermal spraying is a process of applying pure or alloyed metals as coatings onto a wide range of base materials. The metals applied are not paints with metal particles but solid metals that are melted, atomised and sprayed to make a coating.
The atomised molten metal particles cure instantly as they land onto the base material that is normally grit blasted ﬁrst. The grit blasted surface provides the perfect key to produce a well adhered coating.
In most applications, coatings are sealed after metal spraying.
Thermal Spray - Zinc - TSZ 02E
Thermal Spray - Aluminium - TSA 01E
Applied using the same method as zinc, aluminium TSA 01E, is specified when the coating is subjected to especially harsh situations, particularly those encountered in deep sea environments. It can also used as a base coat for Arctec 28E AT – Non Slip Aluminium Titanium coating, where a predetermined thickness is sprayed to meet the necessary heat dissipation values. The video opposite shows an inspection cover being coated with aluminium in preparation for it’s aluminium titanium top coat.
TSA 01E, is also used as a temporary non-slip surface on lightweight decking boards for theatre and concert stages.
