Aluminium Powder Coating

Powder coating is a versatile surface treatment available in a wide range of colours and finishes.

The process uses electrostatic attraction, creating an electric field between negatively charged powder particles and the item being coated, which causes the particles to adhere to the metal surface. The metal is then heat-treated, enabling the coating to flow, and creating an attractive, even and hard-wearing finish.

The powder coating process begins with a series of pre-treatments that clean the metal and prepare its surface for optimum adhesion. Items are loaded into baskets and manually processed through a number of tanks, before being loaded on to a conveyor. The powder coating is applied manually for the best results, before being cured in the oven at a temperature of 160 to 200 degrees C for around 20 minutes.

When cool enough to handle, the parts are checked for quality and packed according to customer requirements.

We are also able to achieve 1000 acetic hours salt spray results on aluminium profiles.

Quality control is a vital part of our powder coating service. We work within guidelines set by British Standards, and hold the following accreditations:

• BS EN ISO 12206:2004 Coatings of aluminium & aluminium alloys for architectural purposes
• BS EN ISO 9227:2006(ASTM B 287) Acetic salt spray test
• BS EN ISO 7253 Neutral salt spray test
• BS EN ISO 1519/3900 Conical mandrel bend test
• BS EN ISO 2409 Adhesion test
• BS EN ISO 2360 Thickness test
• BS EN ISO 2813 Gloss level test
• We are also ISO 9001:2015 accredited.

Our coating service is used for an almost infinite range of applications and aluminium extrusions, wherever an attractive, hard-wearing coating is needed. Some of the typical industries we work with include:

We can supply a total of 200 stock powder coating finishes, and cater to a wide range of colour requirements, including BS 4800 colours, RAL colours, and bespoke colours on request.

Aluminium Powder coating is a quick and relatively inexpensive process. Unlike anodising, it can give good results on metal with small surface defects, reducing the preparation time needed.

Liquid finishes contain solvents that harm the environment and require energy-intense treatment. Aluminium Powder coating is non-toxic and uses less energy during application.

Aluminium Powder coating is one of the many extrusion, fabrication and finishing services we supply in our plant in Herefordshire. Place a single order, and we’ll give you a complete solution.
