Does the thought of buying cheap Corrugated Plastic Signs worry you? Just because corrugated plastic signs are cheap, doesn’t mean they have to look cheap.

Cheap corrugated plastic signs aren’t quite as “cheap” as you may have heard. The public perception of Coroplast corrugated plastic signs is that they are cheap because the materials are obviously so cheap. When compared to other sign materials, corrugated plastic sign sheeting is indeed much cheaper to buy. However, what you may not realize is that it takes exactly the same amount of time and material to design and decorate a corrugated plastic sign as it does an aluminum sign. So the reality is, the only cost difference to make an aluminum sign instead of a Coroplast sign is the difference in the raw material cost of the aluminum panel itself. For example, the cost difference between aluminum metal signs and Coroplast corrugated plastic signs is only about $4.00, for a standard 18” x 24” sign. And yet an aluminum sign looks more professional and will last at least 5 times longer than a Coroplast corrugated plastic sign. Just thought you might like to know.
