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 display in a number of ways.

Corrugated plastic signs are not as flexible as 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 signs, up to 2 years.

The lightweight properties of Coroplast have made it a popular alternative to rigid Acrylic Plastic Signs and PVC Plastic Signs. Corrugated plastic is 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.

Common uses for Coroplast corrugated plastic signs include:

  • Yard Sign
  • Real Estate Signs
  • Garage Sale
  • Political Signs
  • Special Event Signage
  • Directional and Informational Signage
  • Industrial
  • Golf Tournament Sponsor Signs
  • Contractor Promotional Signs
  • Point of Purchase
  • Window Signage
  • Temporary Signage
  • Advertising Signage
  • Trade Shows

Custom Corrugated Plastic Signs can be made in one piece up to 4' x 8'. 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 and political signs.
