We are pleased to be able to provide the best quality Braille signage available on the market. The process not only involves engraving but drilling and placing epoxy dots in the holes to produce the most tactile Braille signage available. These signs are manufactured to exceed Australian and New Zealand standards and are a lot more durable than standard engraved signage. Made from 2 or 3mm Satin Acrylic with ADA Alternative Acrylic tactile symbols and text. These materials are UV Stable.
