Also known as hot dip galvanising, protects steel from corrosion by providing a thick sacrificial metallic zinc envelope, which completely covers the steel surface and protects it from the corrosive action of its environment. The galvanised coating provides outstanding abrasion resistance. Where there is damage or minor discontinuity in the sealing of zinc, protection of the steel is maintained by the cathodic action of the surrounding galvanised coating.
Metallic zinc is resistant to corrosive action of normal environments and hot dip galvanised coatings therefore provide long term protection for steel. By contrast, most organic paints used on steel need frequent renewal and when coatings are breached corrosion begins at the exposed area of steel, spreading rapidly beneath the coating film.
This is a type of dry coating, which is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form.
The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
Auspole takes pride in being able to supply custom, that is site specific, poles. Auspole can provide the pole profiles shown below, according to site requirements. All profiles have the option of being tapered, stepped, or mid-hinged.
