Coroplast Signs

Coroplast is a rigid corrugated plastic sheet made from polypropylene. It has a fluted core similar to cardboard but offers higher strength, moisture resistance, and durability. The material is lightweight, rigid, and weather resistant, which makes it suitable for both indoor and outdoor signage. Coroplast holds printed graphics well and resists warping, rotting, and moisture absorption. It works well for short-term and medium-term signage where durability and low cost matter. The material installs easily using stakes, frames, tape, or mounting hardware.

• Available in 4mm and 10mm thicknesses
• Indoor and outdoor use
• Ideal for yard signs, real estate, events, and political campaigns
• Resistant to moisture and warping

For best value, grouping multiple signs on one panel reduces material waste.
