Powder Coating for Cladding
Aluminium cladding faces considerable wear and tear throughout its service life. UV exposure, driving rain, pollution and the demands of installation mean you need to specify the finish for long-term performance, not appearance alone.
At C&O Powder Coatings we work with aluminium cladding and rainscreen systems of all sizes, from individual feature panels through to full building facades. Our team supports customers from initial specification through to delivery. As a Qualicoat and Qualicoat Seaside certified applicator, every component leaves our plant independently verified to meet the standard.
Powder coating for cladding
Powder coating is a dry finishing process. It applies a protective layer to aluminium cladding components. The powder is electrostatically charged and sprayed onto pre-treated metal, then cured in an oven to form a coating resistant to weathering, impact and environmental damage.
For cladding systems, powder coating combines durability, a wide choice of colours and finishes and low ongoing maintenance. It is the most widely specified finish across the facade industry.
At C&O we regularly coat aluminium rainscreen panels, profiles and associated facade elements used across commercial, residential and public-sector projects. Whether customers work with standard modules or bespoke folded fabrications, our technical team advises on the most appropriate powder, finish and pre-treatment process for the specific application and environment.
Where powder coating is used
Powder coated cladding is specified across new-build and refurbishment projects, particularly for ventilated rainscreens on offices and residential apartment blocks and for façades on schools, hospitals and public buildings. Industrial settings, including the petrochemical sector, also rely on powder coating where long-term durability and corrosion resistance are essential. Architects specify it for feature elements too, including bands, soffits, column casings and architectural details tied into the broader building design.
Why choose powder coating for cladding
Powder coating contains no solvents and produces no volatile organic compounds, unlike wet paint systems. It also offers a broader colour range than anodising and stands up better to chipping and handling damage during installation. Repairs are far easier too, if localised damage occurs during the coating’s service life.
Powder coated cladding requires minimal maintenance. Regular cleaning with a mild detergent solution preserves appearance and performance, with frequency adjusted to suit the installation environment.
From an environmental perspective, powder coating produces no volatile organic compounds and generates minimal waste through powder recovery and recycling. At C&O we have run a chrome-free pre-treatment process for over 12 years, eliminating hexavalent chromium long before it became a regulatory requirement.
Finishes and colour options
Powder coating is available in a wide range of standard RAL colours, along with metallics, textured options and special finishes including anodised effects and natural stone effects. Our technical team advises on the most suitable finish for the installation environment, whether the requirement is colour consistency across large elevations, reduced glare on south-facing facades or a finish concealing handling marks on complex fabrications.
C&O customers choose matt, satin or gloss finishes to suit their designs. Where required, textures diffuse reflections or conceal minor handling marks. We advise on suitable finishes for different building types, exposures and detailing, so the coated surface looks good and performs well in everyday use.
External environment performance
Powder coating provides strong UV and corrosion resistance across the full surface of a cladding panel, including edges, fixings and joints, where inadequate preparation is most likely to allow corrosion to take hold. The electrostatic application process ensures even coverage across complex profiles and folds, which is particularly important for rainscreen systems where panel geometry varies.
In coastal locations or industrial environments, where airborne salts, humidity and pollutants place greater demands on the powder coating, C&O hold Qualicoat Seaside certification. This requires a deeper pre-treatment etch of 2g/m², compared to 1g/m² for standard Qualicoat, removing more contaminants from the aluminium surface and providing a more stable substrate for the coating to bond to.
Pre-treatment and coating process
At C&O, we clean and chemically pre-treat aluminium cladding components through a seven-stage process before applying any powder. This removes contaminants from the metal surface, improves adhesion and ensures the pre-treatment chemistry bonds correctly to the aluminium. We build quality control into every stage of production through our Total Quality Management process. We inspect each component multiple times before despatch rather than relying on a single check at the end of the line.
Standards and quality control
C&O is a Qualicoat and ISO 9001:2015 certified applicator. Independent auditors check our processes twice a year, including unannounced inspections, to confirm we meet the standard. Our internal testing laboratory checks coating thickness, gloss level and adhesion across batches, ensuring colour and finish consistency whether a project is delivered in a single phase or across multiple consignments.
Maintenance and lifespan
Regular cleaning helps powder coated cladding achieve its intended service life. A simple wash-down with detergent is enough to remove dirt, salts and pollutants which preserves both appearance and performance, with frequency adjusted to suit the environment.
Cladding applications
Powder coating suits a wide range of cladding applications. At C&O we coat rainscreen and facade panels for commercial, industrial, and residential projects, as well as panels for recladding and over-cladding buildings where appearance, safety and durability all need upgrading. Industrial and logistics facilities will often use powder coated cladding as part of their branding or to help large buildings integrate with their surroundings because of the wide range of colours and finishes available.
Whatever the sector, a consistent, well-applied powder coating protects the building and maintains its appearance over time.
Why choose C&O Powder Coatings
C&O has over 40 years of experience in powder coating cladding panels. Our in-house technical team supports architects, fabricators and procurement teams in deciding which powder coating colour and finish is best for their project and how it will perform in the intended environment.

Frequently asked questions
What does powder coating for cladding involve?
We clean and chemically prepare the aluminium, apply a dry powder and cure it in an oven to form a continuous, durable film bonded to the substrate. The film protects the metal from the environment
Is powder coating suitable for aluminium cladding?
Yes, powder coating is widely used on aluminium cladding across the facade industry, provided you specify the right pre-treatment and architectural-grade powders.
How durable is powder coated cladding?
When correctly applied and maintained, it offers a long service life with good resistance to UV exposure, weathering and everyday impact. Performance depends on the coating process used, the environment and maintenance.
What finishes are available for powder coated cladding?
Powder coating is available in a wide range of RAL colours, gloss levels, textures and metallic or special effects. Our technical team advises on the best finishes for your project.
