What Is Coroplast?

Coroplast is corrugated plastic: a lightweight, fluted polypropylene sign material used for yard signs, temporary site signs, event signs, political signs, directional signs, and short-term outdoor displays.

Coroplast is popular because it is economical, weather-resistant for temporary use, easy to cut, and rigid enough for lawn stakes or simple mounting. It is a smart choice for corrugated plastic yard signs, corrugated signs, real estate open-house signs, event parking signs, and construction wayfinding.

Use Coroplast for short-term campaigns, yard signs, temporary notices, event signs, job-site directions, school signs, and promotions where speed and cost matter more than premium finish.

For long-term storefront signage, polished interior displays, high-impact retail graphics, or rigid architectural panels, Sintra, Dibond, acrylic, aluminum, or foam core may be better options.
