🌟 Why choose 4mm Coroplast?
- Economical: the most cost-effective option for high-volume promotional, political, and directional signage — order in packs from 5 to 100.
- Full-color impact: printed in vibrant, full-color with UV-cured inks that lock in your design and resist fading in direct sunlight.
- Exceptional durability: rigid corrugated plastic that's inherently waterproof and unaffected by water, oils, and solvents.
- Versatile placement: ideal for outdoor staking, indoor displays, or mounting — with optional H-stakes for ground installation.

| Sides | 1-Sided or 2-Sided printing |
| Mounting | Optional H-stakes; vertical flutes |
| Use | Indoor & outdoor |
⚠️ Important: ordering for H-stakes
To make sure your sign works with standard H-stakes for ground installation:
- Vertical flutes: signs are produced with vertical flutes (the internal channels running up and down) so the stake slides in cleanly.
- Landscape layout: the 18X24 sign is oriented 24″ wide × 18″ high to keep vertical flutes while staying in standard landscape format.
Note: because of the corrugated flute structure, a very subtle linear effect (faint lines) may be visible on the surface — this is normal and gives the sign its rigidity.

Yard sign FAQs
What are your yard signs made of?
Every sign is printed on rigid 4mm corrugated plastic (Coroplast) — the industry standard for outdoor yard signs. It's lightweight, waterproof, and holds up to sun, rain, and wind, with full-color UV-cured ink that resists fading.
Are these yard signs waterproof and safe for outdoor use?
Yes. Coroplast is inherently waterproof and unaffected by regular exposure to water, oils, and solvents, making it ideal for outdoor staking. Prolonged direct UV exposure may gradually soften print vibrancy over time, but our UV-cured inks are built to resist fading.
Do the signs come with stakes?
Stakes are optional. Choose H Stakes included to add ground stakes to your pack, or None if you already have hardware. Signs are produced with vertical flutes so standard H-stakes slide right in.
What's the difference between 1-sided and 2-sided printing?
1-sided prints your artwork on the front only — great for signs placed against a wall or fence. 2-sided prints front and back so your message is visible from both directions, perfect for signs in the middle of a yard or median. With 2-sided selected you can upload separate front and back artwork right in the proof tool.
How many signs can I order?
Signs are sold in packs of 5, 10, 25, 40, 50, 60, 80, and 100. The per-sign price drops as your pack size grows — the proof tool shows your per-sign cost as you choose.
What size are the yard signs?
These are the standard 24″ × 18″ yard sign size, oriented landscape (24″ wide × 18″ high) for H-stake compatibility — the most popular size for political, real estate, and event signage.
