Aluminum – This is a substrate used primarily for, but not limited to, road and safety signage. It is light and very durable. Its outdoor life expectancy is 10 years or more.  

Some signs can be made with aluminum faces sandwiching a sheet of rigid or hard corrugated plastic. This combination makes the sign light, strong and durable. These signs are guaranteed to last 10 years outdoors.

Office Signage - Changeable lobby and office door signage generally made of anodized Aluminum. The edges of the signs clip onto plastic holders that have been attached to doors or walls (usually with double sided tape or screws). They can easily be popped off and changed as needed
