The external aluminium profiles are as standard chrome free and surface treated with a polyester powder coating. This treatment offers a very strong and weather-resistant surface requiring only limited maintenance. In practice, this means cleaning it a couple of times a year with a soft brush or cloth and lukewarm water with a neutral cleaning fluid such as car shampoo.
Minor damage to the surface treatment will not affect the element’s durability since a natural oxide film quickly forms on exposed aluminium, preventing corrosion and white rust attacks.
However, for cosmetic reasons it may be desirable to repair such damage and Idealcombi’s Technical Department would be happy to provide advice and guidance. Call us on 01582 860 940.
