Quality braille signage is manufactured from PVC to a depth of 3mm. That is to say that injection moulded signage cause all graphics to be of a continuous nature. Undoubtedly hygiene and compliance to the Building Code of Australia are the most important factors. The letters and dots are fixed and will not dislodge as they are part of the moulding. Moulded signage means that there will be no adhesive failure on symbols, letters or braille dots, which in turn extend the life of each sign.
