Quality

With over 40 years of leadership in the continuous anodising industry and proven on-site performance of its product in many locations around the world, Coil not just respects international quality standards, but sets the norm for quality in continuous anodising.

Coil is certified ISO 9001:2015.

In order to guarantee the integrity and longevity of the continuously anodised product, Coil carries out regular testing to ensure:

  • Consistent gloss levels of the surface finish
  • Consistent anodic film thickness
  • Consistent colour
  • Quality of sealing
  • Corrosion resistance
  • Weather resistance

For many years, the QUALANOD standard has been the accepted standard for anodising. However, this standard was developed for batch anodising where the production parameters are much less precise, greater colour and gloss variation is accepted and where the anodic film is not flexible, rendering post transformation more difficult.

Coil has recently introduced the QSCA standard for continuous anodising, which is expected to become the new standard for architectural specifications for the continuously anodised product.

A summary of the various quality standards and testing procedures can be found below:

LONG TERM PERFORMANCE

 

In addition to production and laboratory testing Coil has carried out an extensive survey of buildings in various locations throughout Europe to verify the long term on-site performance of the product.

The conclusions, which can be found in the report below provide conclusive evidence of the durability of the anodic layer and its superiority over painted aluminium.
