Coroplast is a tough, waterproof, 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 have made it a popular alternative to rigid Acrylic Plastic Signs and PVC Plastic Signs. Corrugated plastic 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
extremes
- Coroplast plastic signs can be one-sided or
two-sided - They are easy to display
and mount - Coroplast serves as a popular alternative to
foam core mounting board
- Coroplast 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.

We offer more colors for Coroplast corrugated plastic signs than anyone out there on the web!
The Coroplast sign material itself comes in a number of colors. However, if the color you need is not available, the magic of digital printing can take care of that for you! So you can now choose from ANY color under the sun when designing your new signage!
Big or Small, We Do It All!
We offer more sizes of Coroplast signs than anyone else out there on the web! The Coroplast sign material comes in sheets up to 4' x 8', so that is the largest size Coroplast sign available without seams. Larger sizes are possible if multiple sheets are installed together on a flat surface. Coroplast plastic signs are 3mm (approx. 1/8" to 3/16") in thickness. 18" x 24" is the standard size used for most real estate signs, political signs and yard signs.
While we routinely cut Coroplast into custom sizes, we usually only cut it into rectangular or square shapes. We do not cut Coroplast corrugated plastic into very customized shapes. The material does not lend itself to intricate cuts or shaping. Any custom shaping must be kept to a minimum.
Corrugated plastic signs are easy to display! They fit all standard real estate frames, or you can use the more economical Coroplast sign stakes designed for custom yard signs. Coroplast plastic signs have hollow "flutes" that run either horizontal or vertical. The material comes standard with vertical flutes to allow for easy installation of these optional Coroplast sign stakes. But if you prefer horizontal flutes, just let us know and we'll make sure you get what you request.
Coroplast can also be attached to a door, hung inside a window or from ceilings using:
- Frames or stakes
- Suction cups
- Double-sided tape
- Velcro®
- Grommets and eyelets for hanging signs
- Or Coroplast signage can be self-supporting with the use of an easel)

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. Sincerely, Barney Stowes |

Frequently Asked Questions About Custom Coroplast Plastic Signs
Coroplast is a tough, waterproof, corrugated 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.
As you can see in this photograph, Coroplast plastic has hollow flutes on the inner core of the sign material. Corrugated Coroplast has semi-smooth plastic on both the front and back of its core, and its slight ridges can only be seen up close.
Corrugated plastic signs are intended for interior signs (lasting for decades) or short term outdoor signs. Coroplast signage displayed outdoors lasts up to 2 years.
Many materials are stronger than a printed Coroplast sign, however the most common replacement is aluminum.
When it comes to the rigidity of a sign, a vinyl banner is much more flexible than a Coroplast yard sign.
Full color Coroplast signs are the perfect solution when a sign is needed for a short term outdoors. Some of the applications that are most popular are:
- Yard Signs
- Real Estate Signs
- Garage Sale
- Political Sign
- Special Event Signage
- Directional and Informational Signage
- Industrial Signs
- Construction Site Signs
- Golf Tournament Sponsor Signs
- Contractor Promotional Signs
- Point of Purchase Displays
- Window Signage
- Temporary Signage
- Advertising Signage
- Trade Shows
Coroplast is an extremely light weight yard sign. Because of its light weight it is a popular alternative to poster board and foam core mounting board.
Coroplast is not made to withstand winds, however if you place it in a metal frame it will increase the resistance that the Coroplast can withstand.
Coroplast is designed for short term use outdoors. Depending on the vinyl that you choose and the weather conditions your sign is exposed to, your sign can last up to two years in the sun.
Coroplast is not intended for long term use and does not stand up to winds very well. However, if the sign is for temporary use and will be outdoors for only a short period of time, it is often the best answer to your signage needs.
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!
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.
Corrugated plastic signs are not as flexible as the vinyl banner material or as rigid as solid plastic sheets. Although custom corrugated plastic signs are commonly used outdoors, high winds can damage the corrugated sign material. 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 lasts as long as 15 years.
Typically your custom Coroplast sign will ship within 48 hours of your final approval of your proof. If you need it faster than that, just let us know!
Are you concerned that your custom Coroplast brand, corrugated plastic sign may not turn out the way you want?
After all, our sign shop is probably hundreds of miles away from you so how can you be certain your order will turn out right? Fortunately, it only takes seconds to transmit full-color custom coroplast plastic sign designs from our computer to yours because e-mails travel so fast these days.
Upon order approval, here’s how the process works:
- First, your order goes straight to the Art Department
- Our Graphic Designer will then e-mail you a proof
(a “proof” is a picture of what your sign will look like) - Once you review the layout, let us know if you would like to see any changes, and …
- If you have any changes, we will e-mail you proofs as needed until you’re completely happy with your design.
There are a few things to look at for the guarantee of an Coroplast sign. The workmanship is always guaranteed by us for one year. The manufacturer guarantees the Coroplast plastic itself for up to two years.
The other consideration is the vinyl that you choose for your sign. There are two levels of vinyl that we offer, and they each have a different warranty. Intermediate vinyl lettering is intended for short term outdoor signs and is rated for 3-5 years. Our High Performance Vinyl Graphics will last 7-10 years outdoors, even under extreme environmental conditions.
