Material & Durability

Rigid 4mm corrugated plastic construction; engineered to be weather-resistant where oils, solvents, and water have no effect at regular temperatures, ensuring long-lasting endurance.
Versatility

The go-to choice for high-volume outdoor advertising, temporary directional wayfinding, and durable indoor signage that remains lightweight and easy to transport.
Design & Aesthetics

Full-color printing with a subtle linear flute texture; the surface is optimized for high-contrast graphics that remain vibrant even under direct sunlight thanks to UV-cured ink technology.
Ideal Uses

Political Campaigns, Yard Signs, Real Estate, Healthcare, Educational Institutions, and Retail.
Features

Optional grommets for hanging, compatible with metal H-stakes for ground mounting, and a waterproof build that stands up to rain and humidity without warping.
Special Instructions

When using H-stakes, ensure your sign is ordered with vertical flutes and that the width is larger than the height. Please be aware that the corrugated structure results in a very subtle linear effect on the surface. For the best visual results on this textured material, we recommend bold fonts and high-resolution artwork submitted at 300 DPI.
