The surface condition of Aludium’s products depends on the application in which it will be used or the degree of transformation the customer will apply. Almost any surface state is possible including:
- Bright or dull aspect
- Mill finish
- Oiled or degreased
- Raw or protected
- Topography variations.
The condition of Aludium’s finished materials can be classified as:
- Pre-painted quality: Aluminium provided in raw condition after cold rolling which is suitable for painting. The metal can be offered finished (oiled) or in degreased condition.
- Anodising quality: Includes all products with a finish suitable for anodising. Anodising requires specific alloys and special production processes to obtain the best surface finish, free of defects. Defects in the metal will be amplified by the anodising process.
- Pre-anodised quality: Metal suitable for anodising which is delivered to the customer after being anodised by a third-party.
