Unlike lighted signs, there are no working parts to maintain and no energy costs associated with them.
The only drawback is the unfortunate fact that any types of signage eventually fade due to the weather and the sun’s ultraviolet rays. These flat aluminum building signs will last anywhere from 5 to 7 years, and perhaps longer depending on the amount of sunlight and radiant heat that it receives.
The simplicity of these signs, however, make them much easier and therefore cheaper to replace.
