Non-vision grilles are also available in:

Mill Finish: Please note that 'mill finish' means untreated aluminium and is useful if you wish to provide your own finish. A 'mill finish grille' may naturally have light scrapes and abrasions from the manufacturing process. We can polish the scratches out if no finish is to be applied. This finish is referred to as "polished aluminium".
