High-Quality Surface Finishing for Architectural Steelwork and Feature Metalwork
Architectural metalwork requires a combination of visual appeal, durability and technical performance. Components must achieve the desired aesthetic finish while also providing reliable protection against corrosion, weather exposure, UV radiation and everyday use. At TMF – Total Metal Finishing Ltd, we provide specialist architectural metal finishing services for architects, fabricators, contractors, designers and manufacturers throughout the UK. Our in-house capabilities include shot blasting, chemical pre-treatment, powder coating, wet paint systems, Electrophoretic Deposition (E-Coat) and Aluminium Thermal Spray (TSA). These processes allow us to deliver high-quality finishes that enhance architectural metalwork while protecting steel and aluminium components in demanding environments. From feature staircases and commercial developments to public infrastructure and bespoke architectural fabrications, TMF provides controlled finishing solutions where appearance and performance are equally important.

Industrial Shot Blasting
Precision surface preparation for high-performance industrial coating systems. At TMF – Total Metal Finishing Ltd, shot blasting is far more than a cleaning process — it is a precision surface engineering operation that creates the foundation for every successful coating system. Whether components are destined for powder coating, wet paint, Electrophoretic Deposition (E-Coat) or Aluminium Thermal Spray (TSA), long-term coating performance depends upon the quality of the surface preparation carried out beforehand.
Metal Pre-Treatment
Preparing metal for long-lasting protective coatings. At TMF – Total Metal Finishing Ltd, pre-treatment is one of the most important stages of the finishing process. Before powder coating, wet paint or E-Coat can be applied, the metal must be properly cleaned and chemically prepared — helping coatings bond correctly, improving corrosion resistance and extending the life of the finished product.
Industrial Powder Coating Services
Durable powder coating for industrial and engineering applications. At TMF – Total Metal Finishing Ltd, we provide high-quality industrial powder coating for customers across manufacturing, construction, rail, agriculture, automotive and heavy engineering — from one-off prototypes and fabricated steelwork to high-volume production.
Wet Spray
High-performance wet paint finishes for industrial and engineering applications. At TMF – Total Metal Finishing Ltd, we provide industrial wet paint spraying for manufacturers, OEMs and engineering businesses across the UK — from one-off fabrications to large production batches.
Electrophoretic Deposition (E-Coat) Services
Advanced corrosion protection for complex metal components. When corrosion resistance matters, E-Coat is one of the most effective finishing systems available. At TMF – Total Metal Finishing Ltd, we provide high-quality Electrophoretic Deposition (E-Coat) for manufacturers, OEMs and engineering businesses across the UK. Using our modern E-Coat facility, we deliver a consistent, fully enclosed coating that protects complex metal components from corrosion while providing the perfect foundation for powder coating or wet paint. Whether you're producing one-off prototypes or high-volume production batches, we'll recommend the right coating solution to maximise product life and minimise maintenance.
Aluminium Thermal Metal Spraying (TSA)
Long-lasting corrosion protection for steel structures. At TMF – Total Metal Finishing Ltd, we provide Aluminium Thermal Metal Spraying (TSA) to protect steel components operating in some of the harshest environments — from offshore structures and marine equipment to bridges, industrial plant and heavy engineering projects.
Finishing Solutions for Modern Architecture
Architectural metalwork is often exposed to conditions that can affect both appearance and coating performance.
Selecting the correct preparation and coating system at the design stage helps maintain the appearance, durability and performance of architectural components throughout their service life.
- Rain and moisture
- UV radiation
- Atmospheric pollution
- Coastal exposure
- Temperature changes
- Condensation
- Abrasion
- Public interaction
- Cleaning chemicals
- Mechanical wear
Components We Finish
TMF provides finishing services for a wide range of architectural metalwork. From one-off bespoke projects to repeat production programmes, every component is processed with the same attention to finish quality and consistency.
Surface Preparation
A high-quality architectural finish starts with effective surface preparation. TMF's shot blasting and cleaning processes remove mill scale, corrosion, surface contamination, manufacturing residues, previous coatings and oxidation.
Correct preparation improves coating adhesion, reduces the risk of defects and helps maintain finish performance over time.
Chemical Pre-Treatment
Where required, components undergo controlled chemical pre-treatment before coating. For architectural applications, where surface appearance is highly visible, effective pre-treatment is essential to achieving a consistent and reliable result.
- Improved coating adhesion
- Enhanced corrosion resistance
- Greater coating consistency
- Increased durability
- Improved finish retention
Powder Coating for Architectural Applications
Powder coating is widely used throughout architectural metalwork due to its combination of appearance, durability and colour flexibility.
- Balustrades
- Handrails
- Gates
- Railings
- Feature steelwork
- External architectural components
- Excellent colour consistency
- Strong weather resistance
- UV stability
- Wide RAL and BS colour selection
- Matt, satin and gloss finishes
- Fine and coarse textures
- Metallic finishes
- Good impact resistance
- Low maintenance requirements
Wet Paint Systems
Some architectural projects require specialist liquid coating systems due to design requirements, size, environment or specification. Wet paint is particularly suitable for larger fabrications, specialist applications and projects where future maintenance or refurbishment needs to be considered.
- Bespoke colour matching
- Specialist coatings
- High-build protective systems
- Decorative effects
- Repairable finishes
- Large structure coating capability
Electrophoretic Deposition (E-Coat)
E-Coat provides consistent corrosion protection, particularly for fabricated components with complex shapes and enclosed areas. When combined with powder coating or wet paint, E-Coat provides an additional layer of protection while maintaining a high-quality external appearance.
- Fabricated assemblies
- Enclosed sections
- Complex architectural fabrications
- Hidden structural components
Aluminium Thermal Spray (TSA)
For architectural projects located in aggressive environments, Aluminium Thermal Spray provides a highly durable corrosion protection solution. TSA can also be incorporated into duplex coating systems where extended service life and reduced maintenance requirements are key considerations.
- Coastal developments
- Bridges
- Waterfront architecture
- Public infrastructure
- Landmark structures
- Marine-exposed steelwork
