The regulation signs are made of
Aluminum. This material is used for outdoor and regulation signs. It is extremely durable
and will last for many years. Aluminum is available with or without radius
corners or holes. It is also available in different thickness. With this substrate
we primarily use 2-mil vinyl. Aluminum can also be screen-printed.
Aluminum blanks are available in different thickness. 16 gauge is the one
mostly used in the sign industry. The government road signs are made out of
12 gauge.
