Hanging: All parts should have openings in them so they can be hung for coating. We can coat parts that are not able to be hung but please discuss with us first! When parts are hung, there will be a hook mark. If you want to control where the hook mark is then you need to specify where that part is to be hung by.
Masking: Powder coating is very tough and difficult to remove. If you require areas to be masked please get us to do it or ask us to provide masking tape. Normal masking tape is not suitable for heating to 200 C. It masks so well that you will damage the coating trying to get it off. We mask threads with removable masks as standard practice.
Colours: Unless one of the powder manufacturers makes powders specifically to your colour, a standard range of colours, textures and ripple finishes is available. Ask us for a colour chart. Customer colours can me made in as little as 20kg. Rough cost $80 per kg.
Weathering: Do not put yellow, orange or red in the sun. These colours will severely fade after 6 months. Fade or chalking on dark strong colours will occur and be much more noticeable than for weak colours. Do not put rippled or textured powders out doors as they will harbour moisture which will lead to premature corrosion.
Ripple Finishes: Powders can be made as a ripple or wrinkle finish which gives a wavy appearance to the coating. This is good for hiding surface defects such as grinding marks.
Hammertone Finishes: Mimics of the traditional paint finish are available but colour and weathering ability is restricted.
Textured Finishes: The appearance of a texture as a rough surface that diffracts light. The amount of roughness is controllable by the applicator.
Metallics: Powders are available in a range of metallic finishes. They do not ‘flip’ as much as a paint equivalent would.
Appearance: Powder coating is an industrial finish and not automotive one. There will be inclusions in the surface. The film build is between 40 um and 140 um depending on the powder and exhibits more orange peel than paint. (1000 um = 1 mm)
Fencing/Gates: All fencing and gates must be made from glavanised steel and welded with silicon bronze or stainless steel welding wire. The welds are the first part to corrode. If within 5 km of the sea, all parts must be hot dip galvanised and painted, not powder coated.
Sharp Edges: Powder coating & paint shrinks away from sharp edges during curing. This exposes the edge to the environment and accelerates corrosion. We recommend all edges have a minimum radius of 2 mm.
Perforated Steel: Because of the huge surface area and the sharp edges in the steel, only use perforated steel indoors in low corrosive environments for aesthetic purposes.
