What’s The Difference Between Powder Coating And Industrial Painting?

Choosing a finish for a metal component often comes down to two options: powder coating or industrial painting. At Hassell’s Engineering, we’re asked about the difference regularly, usually by customers weighing up durability against cost, or trying to work out which process suits their operating environment. Both protect metal, and both improve appearance, but the way they’re applied and the results they produce are quite different.

Industrial painting uses a liquid coating, applied wet and then cured, often in a controlled spray bake oven. This allows for a wide range of colours and finishes, along with tailored pre-treatment to suit the substrate. It’s a flexible process, well suited to bespoke fabrications and one-off projects where a specific finish or colour match is needed.

Powder coating works differently. A dry powder is applied electrostatically and then cured under heat, forming a hard, even layer once set. Because there’s no liquid involved, there’s no risk of drips or runs, and the finish tends to be thicker and more resistant to chipping.

Powder coating generally offers stronger resistance to knocks, scratches and general wear, which is why it’s often specified for components that will see rough handling or heavy daily use. Industrial painting still performs well in demanding conditions, particularly with the right pre-treatment, but it may need more careful maintenance over time depending on the environment the component sits in.

Industrial painting is usually quicker to turn around for smaller or bespoke runs, since it’s managed entirely on one site with full control over the schedule. Powder coating services often involve an external, specialist vendor, which can add a step to the process but brings access to a wider range of high-performance coatings and finishes.

Neither process is universally better. The right choice depends on the component and how it will be used, and on what finish the project actually calls for. What matters is working with a supplier who understands both options well enough to recommend the right one rather than defaulting to whichever is easiest to offer.

Hassell’s Engineering manages industrial painting in-house and works with an approved network of specialist vendors for powder coating services, so every project gets the finish that actually suits it.
