At Salop Design & Engineering, our advanced Powder Coating facilities are designed to deliver premium surfaces finishing with outstanding durability, consistency, and process control. With two state-of-the-art automated lines, we are one of the leading providers of high-volume and precision powder coating in the UK—offering turnkey finishing solutions from pre-treatment to final cure.
Why Use Powder Coating?
Powder coating is a highly durable, environmentally friendly finishing process used across multiple sectors including automotive, defence, aerospace, architecture, and industrial equipment. The electrostatically applied powder forms a uniform, tough, and aesthetically pleasing finish that outperforms most other paint applications in corrosion resistance, UV stability, and impact strength.
Technical Benefits:
Advanced Automated Lines
Our two automated powder coating lines include precision-controlled spray booths, inline pre-treatment tunnels, and continuous bake ovens. These lines are capable of handling high-throughput production volumes with minimal operator intervention, ensuring consistency and reduced human error.
Static Application Technology
Using electrostatic spray guns, we achieve a uniform powder deposition even on complex part geometries and hard-to-reach areas. This ensures full coverage with minimal overspray and material waste.
Material & Colour Versatility
We offer a wide range of powder formulations including polyester, epoxy, and hybrid coatings in gloss, satin, or textured finishes. RAL, BS, or custom colours are available, with rapid changeover capabilities for flexible batch scheduling. Colour changes can be completed in under 10 minutes, minimising downtime and improving responsiveness for mixed production environments.
Exceptional Corrosion Protection
With salt spray test results exceeding 1000 hours (ASTM B117), our powder coatings provide robust corrosion protection suitable for outdoor and industrial environments.
Environmental Compliance
Powder coating generates zero VOC emissions and requires no solvents, making it compliant with REACH and environmentally preferable to traditional wet spraying.
Environmental Compliance
We regularly conduct cross-hatch adhesion testing, impact testing, salt spray testing, and film thickness validation to ensure all coatings meet customer specifications and international standards.
Multi-Stage Pre-Treatment Systems
Both lines include automated multi-stage pre-treatment systems (typically involving alkaline degrease, rinse, phosphate conversion coating, and deionised rinse) to ensure optimal surface preparation. This process is critical to achieving strong powder adhesion and long-term corrosion resistance.
Controlled CuringProcess
Our curing ovens feature precise time and temperature controls to ensure full cross-linking of the powder resin. This produces finishes with excellent mechanical properties—abrasion resistance, chemical resistance, and high gloss or matte retention.
Large Component Capacity
Our systems can accommodate components up to 3.5 metres in length and 1.5 metres in height, suitable for panels, frames, enclosures, subassemblies, and decorative structures.

Industry 4.0 Technology Integration
Our powder coating lines incorporate Industry 4.0-ready technology with real-time process monitoring, data logging, and intelligent system feedback. This ensures consistent quality, predictive maintenance scheduling, and enhanced traceability—adding value for customers in regulated or safety-critical sectors.
Application Example:
Our powder coating lines are used to finish high-precision components such as automotive subframes, HVAC panels, battery housings, telecom enclosures, and defence-grade fabrications. These parts require superior corrosion protection and uniform aesthetics for both functional and appearance-critical applications.
