High-capacity powder coating for steel, aluminium and fabricated components, supporting industrial, manufacturing and construction projects across Hertfordshire, Essex and London.
Industrial powder coating is a finishing process where dry polyester or epoxy powder is applied electrostatically to metal components and cured in an oven at 180–200°C. The cured coating forms a hard, durable layer that protects metal against corrosion, impact, chemicals and weathering — making it the standard finishing method for structural steelwork, fabricated assemblies and production components across the UK.
Spraytech provides industrial powder coating from two facilities in Bishop’s Stortford, Hertfordshire. We operate six ovens with up to 10 metres of capacity, handling everything from small brackets and enclosures to long structural steel sections and heavy fabricated assemblies. Our 48-hour average turnaround on standard work means your production or construction schedule stays on track.
We support a wide range of industrial applications:
Structural sections, beams, brackets and fabricated assemblies coated to specification for construction, infrastructure and engineering projects.
Batch production runs of enclosures, frames, panels and components with consistent colour and finish quality across every item.
Batch production runs of enclosures, frames, panels and components with consistent colour and finish quality across every item.
Components and assemblies finished to customer specification, ready for integration into larger products and systems.
Steel fabricators choose Spraytech because we understand the demands of fabrication and construction projects.
Our powder coating facility is designed to handle large volumes, heavy components and complex items, making us a reliable partner for industrial-scale projects.
We maintain strict quality control to ensure uniform coating across all items, whether for batch production or repeat orders.
We understand the importance of keeping production and project schedules on track, delivering consistent turnaround times for industrial clients.
Every job includes appropriate preparation, including cleaning and shot blasting where required, ensuring strong adhesion and long-term durability.
We have supported a wide range of projects across construction, manufacturing and infrastructure sectors throughout the UK.
We act as an extension of your production process, not just a supplier.
Project review and specification assessment
We review drawings, finish schedules and specifications to confirm the coating system, colour, film thickness and any testing or certification requirements before work begins.
Surface preparation and pre-treatment
Components are degreased, shot blasted to ISO 8501-1 Sa 2½ standard and chemically pre-treated. Mild steel receives iron phosphate; aluminium receives chromate-free conversion coating. Items are coated within 4 hours of blasting.
Powder coating application
Powder is applied electrostatically by experienced operators who adjust gun settings for each component geometry, ensuring even film thickness across flat surfaces, recesses and complex fabrications.
Controlled curing process
Items are cured at 180–200°C for 10–20 minutes. For heavy structural sections, metal temperature is monitored with thermocouples to ensure the full cross-section reaches cure temperature.
Final inspection and quality checks
Film thickness, adhesion, colour accuracy and surface finish are checked on every item before dispatch. Coating thickness readings are recorded and available on request.

Industrial powder coating is a finishing process used to protect and enhance metal components, providing a durable and corrosion-resistant coating.
We coat mild steel, aluminium, galvanised steel, cast iron and stainless steel. Each material receives a specific pre-treatment process — shot blasting and iron phosphate for steel, chromate-free conversion coating for aluminium — to ensure long-term adhesion and corrosion resistance.
Our average turnaround for standard industrial work is 48 hours from receipt of prepared components. Larger programmes are scheduled to align with your production or construction timeline. We confirm turnaround at the point of quoting.
Yes. We measure film thickness on every item using a digital coating thickness gauge and can provide batch test reports and thickness records on request. This documentation is often required by specifiers and main contractors as part of quality assurance.
Yes. Shot blasting and chemical pre-treatment are included as standard on every industrial job. We do not charge separately for preparation unless it is requested as a standalone service without coating.
