A. There are many factors that will contribute to the longevity of your sign. The type of material the sign is made from will be the biggest factor. Other things to consider are the type of environment the sign will be installed in. Will it be placed in an interior or exterior location? What type of regular maintenance do you plan to perform on your sign if any? Is it likely that the sign will be damaged or vandalized where it is installed? Will the sign be exposed to standing water, dust and dirt or a salty air environment? When answering these questions it is important to consider what material will work best for your application.
