Every new facility must be accessible to all persons, including people with sight problems. For this reason, it is a requirement by law to install braille signage in every entryway, including offices and restrooms. It is important to note that braille signs can be made from different materials, such as acrylic and metal. Notably, you should pay attention to the rasters. The objective is to use materials on the braille characters that will ensure persons with eye problems can instantly make out what the sign says. This article highlights common materials for braille rasters.
Lost characters are one of the main issues facility managers have to deal with in as far as custom braille signs are concerned. It is usually the case on braille signs where the rasters are glued to the surface. That is why you should pull all the stops to find a sign fabricator who uses epoxy for braille characters. This is because epoxy is incredibly strong once it is mixed with a hardener and allowed to settle. When applied to braille spots, the epoxy adheres tightly onto the surface, thereby eliminating any possibility of the rasters falling off in the future. Additionally, epoxy braille characters are extra smooth and friendly to users' fingers.
Another material you should look at when ordering custom braille signs is acrylic. From far away, acrylic rasters can be easily confused for epoxy rasters mainly because both are transparent. The only difference is that acrylic braille characters are cloudy and not as clear as epoxy. This makes them easily identifiable to persons with partial eyesight issues. Another advantage that plastic dots have is that they can withstand direct ultraviolet rays. Therefore, they are not easily discoloured by direct sunlight, and this ensures the braille sign remains pleasing to the eyes of clients with normal eyesight.
When you cannot afford braille signs with acrylic or epoxy rasters, then rubber comes in hand. However, that does not mean that rubber rasters cannot perform their function. While rasters made from acrylic or epoxy feel tactile, the rubber feels soft to the touch. The advantage here is that even people with sensitive hands can comfortably use rubber braille signs without hurting their fingers. Unfortunately, rubber rasters readily attract dust and dirt; therefore, they are not the easiest to maintain. The only way you can keep the rubber rasters clean at all times is to clean them every morning and every evening.
