Coroplast Sign Design in Mountain View, California

Do you know what Coroplast is?


Ever see those real estate signs on the lawns of houses for sale? The ones that are held up by two thin metal rods that are pushed into the ground? If you ever see one of those, walk up to it and have a look.


Coroplast is more commonly referred to as “plastic cardboard”. It is a plastic material that has corrugated edges to it.


Why Coroplast?


If signs and banners were a family, Coroplast would be that one cousin we all have who walks around in the winter snow in a t-shirt, flip flops and shorts. It is rugged, heavy duty, water proof and makes for a great indoor or outdoor sign material.


The hollow fluted design (corrugated) of these signs make them extremely light weight, easy to handle and simple to use and display in a wide variety of ways. They can be either indoor or outdoor signs.


Signs that are made out of Coroplast are generally preferred to cardboard, foam core mounting board, and poster board. These other types of materials are not water proof and their surfaces are much more susceptible to damage than corrugated plastic.


Foam core mounting and poster boards are generally relegated to middle and high school science projects. If you want a sign, you’re going to want to print it on material that can stand the test of time and temperature. Standard thickness is 3/16" and goes all the way up to ½”.

The beauty of these signs is their rugged durability. They can easily withstand very hot or very cold temperatures. Real estate agents in the South Pole love this kind of material because they won’t rot or damage in sub-zero temperatures in the middle of a howling blizzard.


You can also print almost anything on this material. Any color, any picture or graphic logo. It will all stick and take. There are many color options to choose from and the signs come in a wide variety of sizes as well.


If you store or display them indoors, these signs will last for decades as they are made out of a rugged plastic material that will not rot or fade. If stored outdoors, the overall lifespan can be anywhere from 2-5 years, depending on usage and a few other factors.
