Mill Finish Processing

Mill finish is basically bare aluminium,it is the natural appearance of the aluminium,the extrusion profiles without any surface treatment as it comes from the extrusion die.it is simple products after the extrusion processing.The appearance is natural color of aluminium in sliver,as without any surface,there will be some die lines as surface texture,but without any external mechanical or chemical finishing or colouration.

Our extrusion process produces high quality mill finish aluminium.
All profiles come out smooth and uniform because of our carefully monitored production process.The extrusion dies are carefully maintained so they enhance the smoothness of the profile surface. Be free from Oil Stain, Dent, Inclusion, Scratches, Stain, Oxide Decoration, Breaks, Corrosion, Roll Marks, Dirt Streaks and other defect which will interfere with use.
