Frequently Asked Questions

What are blank corrugated plastic signs typically used for?

Blank corrugated plastic signs are one of the most cost-effective signage materials available, widely used by political campaigns, real estate agents, contractors, lawn care companies, screen printers, vinyl sign shops, schools, charities, and nonprofit organizations. Their lightweight, weather-proof construction makes them ideal for both temporary outdoor display and indoor applications.

Why choose the 18" × 24" portrait format over a standard horizontal sign?

The portrait orientation is ideal when your design has more vertical content—such as a phone number stacked below a name, a tall logo, or real estate-style layouts. It offers the same 432 square inches of display area as the popular 24" × 18" size, just rotated 90 degrees for a different visual impact.

What colors are available and is there a price difference?

Blank signs are available in White or Yellow. White is the standard choice and most popular for printing and vinyl applications. Yellow is available at a slight additional cost per sign. Keep in mind that ink colors may appear differently when printed or painted on yellow material. Select your color at checkout.

Which direction do the flutes run on the 18" × 24" signs?

The flutes run vertically—top to bottom along the 24" dimension. Sign stakes slide up into the flutes from the bottom for a secure, tool-free installation compatible with our 15" and 24" H-stakes.

Are grommets available on the 18" × 24" blank signs?

Yes, grommets can be added for hanging or fence mounting applications. This option is not available online—please contact our team or call 1-800-513-1695 for details and pricing.
