We cut these 4mm signs from extruded PP hollow sheets. The fluted design keeps them light, but they are stiff enough to stand up outside on their own.
Paperboard or foam will go soft and curl when it rains. These PP signs don't. They hold their shape in the rain and sun, which saves you money because you don't have to replace them halfway through a campaign.
Most of our customers stick with 4mm. It's the industry standard. You get the stiffness you need without paying extra for shipping heavy boards.

FAQ
Q: Why is 4mm considered a standard thickness for lawn signs?
A: It's stiff enough to stay upright outside but light enough to keep shipping costs down. That's the main reason people buy it.
Q: Are these signs fully waterproof?
A: Yes. PP doesn't soak up water, so the size and shape stay the same even if they sit in the rain.
Q: Do they work with standard H-stakes?
A: Yes. The hollow flutes fit standard wire H-stakes, like the ones used for real estate signs.
Q: Which printing methods are recommended?
A: UV printing works best for small batches or detailed logos. Screen printing is cheaper if you're ordering a large quantity.
Q: Can the signs be reused?
A: Yes. Just take them down carefully and store them flat. You can use them again for the next event.
Q: Can I request custom sizes or shapes?
A: Yes. We do custom cutting and die-cut shapes. We can also match Pantone colors for your brand.
