Custom Coroplast (Corrugated Plastic) Signs

Close up of the Corrugated Plastic Sign Material

Corrugated plastic, also known by the brand name Coroplast®, is a tough, waterproof, plastic sign material which resembles the appearance of “plastic cardboard”. The hollow-fluted design of Coroplast makes this sign material extremely lightweight, easy to handle and simple to display in a number of ways.

The lightweight properties of Coroplast makes it extremely versatile, and has made it a popular alternative to rigid Acrylic Plastic Signs and PVC Plastic Signs. Coroplast signs are also commonly preferred over poster board and foam core mounting board. Foam core is not waterproof and the surface is much more sensitive to damage than corrugated plastic.

Here are the key points to know about custom Coroplast plastic signs:

  • They have a slightly ribbed surface
    that looks like "plastic cardboard"
  • They're ideal for short term outdoor
    use (Good for 1-day event signs
    and last up to 2 years)
  • They'll last for decades indoors
  • They are completely waterproof
  • The standard 3/16" thickness
    (4mm) feels similar to stiff cardboard
  • Coroplast is readily available
    in a highly rigid, 1/2" thickness
  • They have high tolerance for
    cold and hot weather temperature
  • Coroplast plastic signs can be one-sided or
  • They are easy to display and mount
  • Coroplast serves as a popular alternative to
    foam core mounting board
Plus, custom Coroplast signs are highly versatile
  • Coroplast custom signs can be made
    any size you want
  • Any design, artwork, photo or logo
    can be used
  • And you can choose from virtually any
    color you want.

I didn’t have a ton of money to sink into my advertising but I needed to get my message out. I found coroplast plastic signs to not only be cost effective but I found them to be of very high quality and durability. My financial return was great and although my budget has grown, I still use these signs because of their easy placement and low cost.

"When do plastic signs that look like “plastic cardboard” become a good choice?"

Coroplast Signs Just because corrugated plastic signs are cheap doesn’t mean they have to look cheap. Most people looking at signs don’t know what they’re made out of anyway — nor do they really care. When you look at signs, what do you see? The message, the colors and any graphics, right?

You can dramatically increase the effectiveness of your advertising display by focusing on these design elements. With an attractive layout and color scheme, an otherwise ordinary piece of “plastic cardboard” can be turned into a highly effective sign for your business. When you’re ready, our Art Department can create an alluring, eye-catching design for you!

"Are the Coroplast plastic sign myths true?"

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.

Corrugated plastic signs

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.

"How long do Coroplast plastic signs last?"

Corrugated Plastic Signs are the ideal material for real estate and political signage

Corrugated plastic signs are intended for both interior signs and short term outdoor signage. Coroplast signs used outdoors last up to 2 years, while indoor Coroplast signage can last for decades.
