Barley Chalu Ltd offer the application of a comprehensive range of architectural grade polyester powder coatings for the home improvement / fenestration systems & general extrusion market. This represents a cost effective route to achieving a durable and colourful finish, ensuring quality products and innovative technologies are available to meet current and future needs of our customer base.

Finely divided polyester powders are given a polarised electric charge from a high voltage generator. The particles, being similarly charged repel each other and seek an earth (the article to be coated). The coated components are heated to 200^oC for 10 minutes causing the powder to melt, flow and chemically react to form a continuous film which is firmly anchored to the substrate. Electrostatic coating, as the process is known, provides good coverage as the powder tends to 'wrap around' the profile.

Colours can be chosen from the extensive RAL or BS colour ranges in matt, satin or high gloss or can be matched to any customer specification in flat, metallic or textured finishes.
