What Is Polished Aluminium?

Polished aluminium undergoes a finishing process resulting in a smooth and reflective surface. The process usually entails an initial grinding to remove any imperfections followed by sanding to smooth the surface. Higher grit sandpaper is applied to achieve an even finer finish and finally, a polishing compound is used to create the mirrored look. Polished aluminium alloy maintains its lightweight and corrosion-resistant properties whilst giving a more aesthetically pleasing appearance overall.

Brush polishing is a method in which metals like aluminium are finely sanded using light grade bristles or sandpaper. This gives the metal a very tasteful matte appearance with an almost grain like directional finish. At Aluminium Online, we stock a broad range of products, including polished aluminium flat bar, polished aluminium sheet, polished aluminium angle, polished aluminium angle trim and more.

  • A brushed finish features fine lines
  • A matte finish is created by using fine abrasives resulting in a smooth surface with little shine
