Each  Stainless Steel BrailleFace Braille Sign is formed from a single piece of  Stainless Steel creating a true continuous faced Braille Sign with no parts fixed to the sign in any way. This creates excellent durability with it being almost impossibly to forcibly remove any Braille or Raised components as well a delivering outstanding hygiene properties with no joins on the sign face that can harbour nasty bacteria. BrailleFace Braille Signs are also non-combustible.
