NSP Coatings Ltd offer Hot Zinc Spraying of steel and aluminium components both 'as srayed' and as a primer for powder coating.
For 2013 we have invested in a new Arc spray unit allowing us to take on larger jobs and acheve higher production rates with a wider range of finishes.
In the METALLISATION FLAMESPRAY process, the raw material in the form of a single wire is melted in an oxygen-fuel gas flame. This molten material is atomised by a cone of compressed air and propelled towards the workpiece.
molten zinc spray solidifies on the component surface to
form a dense, strongly adherent
suitable for Corrosion
Protection or component Reclamation.
Major advantages of the Flamespray process are that the zinc coating is available for almost instant use with no drying or curing times and there is no risk of damaging the component.
Hot Zinc Spray is ideal for external applications such as architectural metalwork as well as for use in corrosive environments.
Our Hot Zinc Spray process uses Metallisation Wire 02E Zinc (Zn).
Surface pre-treatment is achieved through grit blasting to SA2.5 to provide the best possible key for the zinc layer.
Zinc is applied to spec, normally 50-100 microns.
Zinc spray is suited for items upto 2.5 tons and 13m in length.
