Powdercoating of Aluminium:

Powder coating is a type of coating that 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 applied electrostatically with compressed air and is then cured under heat to allow it to flow and form a "skin."  Powder coating comes in two types namely Polyester (exterior) and Epoxy Polyester (interior). There is a wide range of colours available to suit any design or concept. All powdercoating done by Cloud 9 on aluminium is Polyester powdercoating. Powdercoating is maintenance free and just needs to be cleaned as is required using soapy water.

All powdercoating of Aluminium that is done by Cloud 9 is done at SABS 1796 (the SABS Mark for powdercoating) approved powdercoating factories. Due to the fact that the powdercoating is done in accordance with the SABS 1796 mark it is guaranteed for 15-years. The guarantee applies to fading and peeling of the coating.

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. Powder coating is mainly used for coating of metals, such as "whiteware", aluminium extrusions, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.

Galvanizing of mild steel:

Cloud 9 has all structural steel Hot-dip galvanized. It is the process of coating steel with a thin zinc layer, by passing the metal through a molten bath of zinc at a temperature of around 460 C. When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that stops further corrosion in many circumstances, protecting the steel below from the elements. Galvanized steel is widely used in applications where rust resistance is needed, and can be identified by the crystallization patterning on the surface (often called a "spangle").














All steel used in structural situations is galvanized in accordance SABS ISO 1461 the relevant mark for galvanizing. The galvanised steel is then Degreased, Primed with a galvanizing etch primer and then painted using Exterior quality enamel paint.

Powder coating produces a high specification coating which is hard, abrasion resistant and tough. The choice of colours and finishes is almost limitless.
