We also offer automatic powder management systems, for boosted efficiency and automatic recycling of overspray – and can advise on custom coating solutions.
Purposes of spray painting metal
Metal spray painting, both manual and automatic, is significant across many South African industries.
For example, applications range from industrial spraying of steelwork, structural steel and pipes to coating of construction or agricultural machinery and spraying of metal furniture and appliances.
The process of coating metal components can dramatically improve their durability, reliability and aesthetic value.
Depending on their type, metal coatings can:
- protect metal against corrosion, abrasion and/or specific types of chemical damage
- provide lubrication to reduce friction
- add either non-stick or non-slip properties
- create a thermal barrier or improve fire protection.
Powder coating metal
Powder coating typically achieves a thicker coating than wet spray painting. This can provide a superior finish, with greater corrosion resistance and durability.
Initial costs may be higher, however. Powder coating also isn’t as versatile as wet spray painting, in terms of being able to mix, match and touch up colours.
Overall, the intended application and your budget will help determine which is the best choice.
Choosing a spray system for metal coating
It’s worth getting expert advice before deciding on the best spray system for a metal coating application. Also bear the following considerations in mind.
Spray system technology
Each type of spray system – air-atomising (HVLP or LVLP), airless, air-assisted airless or electrostatic – has pros and cons in terms of cost, transfer efficiency and application speed.
The best choice will depend on factors like:
- the type and volume of coating that’s required
- whether the work will occur on- or off-site
- your budget (and any potential for saving on existing costs).
The required metal coating type – whether solvent- or water-borne – is also a consideration. For example, not all sprayers and nozzles are designed to support high-solids coatings.
Spray unit ergonomics
For manual spraying, ease of use is an important consideration. Opt for a spray gun that’s reasonably lightweight, with a soft two- or four-finger trigger. Also check for easy adjustment of spray speed and pattern, and ease of cleaning.
Possible advantages of automation for your business
Automating even part of a metal finishing process can lead to significant savings in time and materials, and result in better, more consistent finishes.
