Zinc arc spraying is a superior method of applying a zinc protective coating instead of hot dip galvanising.
It has the advantages of being able to be applied to large items - much larger than can fit in a hot dip galvanising bath, it does not cause distortion as can the hot dip process, and it can be site applied or touched up. The coating thickness can be varied to suit the end use.
The completed material can be overcoated with a variety of finishes. It is commonly coated with an aluminium vinyl sealer, and it can be overcoated with most paints, or it can be left as is.
