Coroplast Signs


Coroplast is a printable corrugated plastic made of polypropylene that is commonly used for inexpensive and temporary outdoor signage. Similar to cardboard, Coroplast is constructed with two flat printable boards separated by perpendicular interior flutes that build thickness and strength. This makeup gives the signage the lowest price point available of all rigid printable substrates in addition to being lightweight, mobile, and 2-side printable. It’s a flexible graphic that can be utilized in indoor poster board as well as short term outdoor use. Dubbed “plastic cardboard,” Coroplast sees a wide variety of usage in the enterprise world, including:
  • Special event signage, Informational signs, Directional indicators, Menu boards, Temporary signage, Promotional advertisement, Election, campaign or town event indicators, Tradeshows, Short term yard signage.

Most commonly seen on the lawn or in front of a store, Coroplast signs are intended to be viewed from the front or the back. This twin wall signage is traditionally printed with only a couple of colors to remain eye-catching because it usually has a farther viewing distance than other signage types and needs to remain readable. Coroplast signage is used to increase the effectiveness of local or regional marketing or to generally spread awareness among the public.

With a weather-resistant plastic construction, low price point, and rigidity, it’s no wonder why Coroplast graphics are often found as lawn signs. Double-sided printing is also easily possible, maximizing the sign’s range of effectiveness.


Signs Done Fast can print Coroplast signage as large as 60”x120” in size. When purchasing a Coroplast graphic, Signs Done Fast also recommends one of these types of mounting hardware:

  • Purchasing a metal H-frame or wire stakes (Step Stake) and slide metal ends into the fluted side profile of the material and anchor the sign in the ground.
  • Using zip ties to attach the sign to a wall, pole, or other existing structure.
  • Utilizing double-sided tape as an adhesive.
  • Adding holes into the sign and using suction cups with hooks to hang the graphic.
  • Sliding the sign into a channel frame as an alternative to metal H-frame yard signs
  • Purchasing a cardboard easel or finding some other method of self-support.

Each method brings its own advantages and drawbacks. For organizations seeking blanket local promotion, the metal step stake allows both sides of the Coroplast sign to be visible. However, this method is limited to placing the signage in the ground soil. It’s also important to know that since Coroplast is available in many thicknesses the flute channel size varies and thus H-stakes / Step Stakes are not a 1 size fits all.


To maximize the effectiveness of Coroplast signs, Signs Done Fast suggests the following:

  • Print on each side of the Coroplast to enhance promotional visibility.
  • Use limited color selection so as not to clutter the image on smaller signs.
  • Reduce word dependency, allow the customer to process the full meaning in seconds.
  • Design a compelling graphic that makes consumers want to keep looking.
  • Make sure the brand logo is clearly visible when applicable.
  • Utilize wire stakes or a sign frame to make the both sides of the sign clearly visible.

Coroplast can last and maintain it’s quality for as long as 1-2 years outdoors. Coroplast signage does become brittle over time and will begin to crack after long term use.  All forms of printed signage fade over time depending on sun exposure, temperature, orientation, and moisture.

Coroplast is greatly suited for outdoor use since they are waterproof and weather resistant. Although close attention should be given to how they are installed as their stability can be affected by strong winds.
