Industrial powder coating is the go-to finishing method for metal components that need to perform reliably in demanding environments – durable, cost-effective, and capable of handling high volumes without compromising quality.
At Frederick Cooper, we’ve been finishing components for industry since 1879, handling everything from small complex fabrications to large-scale production runs across a range of substrates.
What Is Industrial Powder Coating?
Powder coating works by applying electrostatically charged powder to a grounded metal component, which is then cured in an oven to form a hard, continuous protective layer. It contains no solvents, emits little to no VOCs, and delivers a thicker, more durable finish than liquid paint in a single pass.
At industrial scale, consistent pre-treatment, process control and throughput management are what separate a coating that holds up in service from one that fails prematurely.
Our Industrial Powder Coating Process
Quality industrial powder coating depends as much on what happens before the powder is applied as on the application itself. Our process is structured accordingly.
- Inspection & Assessment Components are inspected on arrival. We check for existing coatings, surface contamination, alloy type, masking requirements, and any features that need protecting during the process. Identifying issues at this stage avoids problems and rework downstream.
- Metal Preparation Thorough metal preparation is the foundation of a lasting industrial finish. This includes degreasing to remove oils, release agents and fabrication residues, followed by pre-treatment to create a chemically receptive surface that the powder can bond to – and that provides first-line corrosion protection beneath the topcoat.
Where surface condition requires it, we also offer media and shot-blasting to remove existing coatings, mill scale or rust, and linishing, sanding and filling for surface refinement prior to coating.
Pre-treatment is not a step that can be skipped or rushed in industrial work. It is where coating failures start.
- Masking Threads, bores, mating faces and any features that must remain coating-free are masked before application. We offer bespoke mask cutting – both vinyl and traditional masking for complex or high-volume components.
- Electrostatic Powder Application Powder is applied electrostatically, giving it a charge that draws it consistently onto the grounded component. This delivers even coverage across flat faces, edges and recesses with minimal material waste.
- Oven Curing Components pass through our ovens at the temperature and dwell time specified for the powder chemistry and component mass. We have five powder coating lines, allowing us to manage different batch sizes, cure profiles and scheduling requirements concurrently.
- Inspection & Sign-Off Finished components are inspected for coating thickness, adhesion, and appearance before leaving the facility. In-house testing equipment is available for detailed verification. For customers requiring it, we can provide PPAP and PSW documentation.
Materials We Coat
We work across a full range of metals including aluminium, stainless steel, zinc and galvanised steel, mild steel, magnesium and copper. Each substrate has specific pre-treatment requirements – we have the process knowledge to handle them correctly.
Not sure which finishing process is right for your parts? Where powder coating isn’t the best fit, our wet paint spraying service may be.
Colour & Finish Options
Industrial powder coating doesn’t mean a limited finish palette. We coat to RAL, Pantone and BS colour standards as standard, with finishes available from high gloss and satin through to textured, matt and wrinkle effects. Whether you need a functional single-colour industrial finish or a precise colour match for a branded product, we can match your specification.
We work with a wide range of powder suppliers and can put forward solutions to specific powder requirements, including specialist chemistries for enhanced chemical resistance, heat resistance or outdoor performance.
