Aluminum signs are made entirely of aluminum. For the sign to be durable and ridged, the aluminum must be thick, which becomes expensive.
Thick aluminum offers durability and resistance to rust and corrosion.
Aluminum composite signs, on the other hand, consist of a polyethylene core sandwiched between two thin sheets of aluminum. This makes them more cost-effective as ess aluminum is used, while providing the same durability and resilience to corrosion.
