Coroplast Sign are made of 5mm corrugated polypropylene sheet with a ribbed interior that looks like “plastic cardboard.” This structure keeps the sign light, rigid, and practical for fast communication across active jobsites, real estate properties, and temporary routes at events.
It accepts full-color printing on one or both sides, and grommets can be placed in any position you request. Signs are offered in fixed standard sizes.
The 5mm thickness of the Custom Coroplast Sign provides more strength than standard 4mm PVC sheets while staying light enough for fast installation. These signs work outdoors for short-term use and can last longer indoors. They support safety messages, directional signs, event routing, promotional displays, and every-day field communication.
A simple and functional material for consistent project communication.

Coroplast signs work well alongside the equipment already used to organize a jobsite. They can be mounted on temporary fence, placed on steel barricades, or added near water-filled barriers to keep routes, access points, and safety messages visible.
