Alcan has solution for surface variations

  • Comment

I was interested to read the article on cladding by George Demetri (AJ Focus, February 2002).

I sympathise with problems of surface variations experienced on some anodised aluminium rainscreen panels (as stated on page 19).

However, it has not been necessary to wait for new processes using aluminium coil to overcome this problem. Alcan's J57S aluminium sheet (featured on page 67), carries a product warranty of reproducible and uniform colour when it is anodised to appropriate standards.
