Achieving a quality finish is paramount.  To help prevent colour variation or ‘tiger striping’ it is important to supply 'anodising quality' sheet.

The industry is being supplied both quality and inferior sheet for anodising.  We are suggesting the following steps to alleviate these problems.

• We require anodising grade alloy 5005 H34.  This available through Garmco or Aleris Distributors.  Garmco is out of Bahrain,  Novelis J575 and Aleris out of Germany both products provide the anodised finish with metallic lustre.  
  We recommend trials be run on any alternative aluminium due to varying chemical compositions and to ensure the expected finish is achievable.
• For large facades please provide a 'Mill Certificate' with metal.
• Metal must be free of any tape, adhesive or oil residue.
• Small contact marks are visible on the front face and 50mm wide contact marks are visible on the back of panel.  (See Production Gallery for details)
• Tags required for clamping purposes should metal be cut to size.
• Welding rod to be 5356 alloy.
