Are Plastic Polypropylene Signs Durable Outside?

If you are investing in outdoor signs - whether for commercial promotion, event marketing or real estate signs - durability is non-negotiable. As a polypropylene sign manufacturer with 14 years of production experience, let Henan Enda Company explore the durability of polypropylene outdoor signs with you.

Polypropylene (PP) is a thermoplastic that can withstand harsh conditions. Its properties make it a good choice for making outdoor signs:

Waterproof & moisture-resistant: Unlike paper or cardboard signs that soak up rain and mildew, PP plastic repels water completely. Even after heavy downpours or morning dew, the sign stays dry. This makes it perfect for rainy regions or areas with high humidity.

UV-resistant to fading: Sunlight’s UV rays are a common enemy of outdoor signs, causing colors to fade and text to blur. PP signs, especially when used in conjunction with UV printing technology (which we use), resist sun damage for months—even years. This enables commercial logos to remain vibrant even in the hot summer.

Impact & scratch-resistant: PP plastic features a unique hollow structure, making it less prone to deformation and damage. Unlike glass or thin metal signs, it can handle minor impacts without damaging the design, keeping your information intact.

The use of PP logos in real outdoor scenarios can also prove their durability:

All-weather adaptability: Whether it’s freezing winters or hot, dry summers, PP signs hold their shape and quality. We’ve had customers use our PP signs for seasonal campaigns (like Christmas or Halloween) and reuse them year after year.

Low maintenance: Unlike wood signs that need repainting or metal signs that rust, PP signs require almost no upkeep. A quick wipe with a damp cloth removes dust or dirt, and they’re ready to look like new again.

Easy to install and maintain pp plastic signboards

PP signs don’t just last—they’re also easy to work with:

Lightweight & easy to install: They are much lighter than metal or wood, so they are very easy to install. We offer H stakes that can be easily installed on your yard or farm lawn.

Customizable for any need: You can customize the polypropylene plastic outdoor signs you need at Enda. From the thickness of the board (1.8-15mm or custom) and the size (standard size 18*24cm or custom), to the shape and pattern of the signboard, you can have one-stop customization here. We have professional staff to confirm your specific needs with you and produce the most satisfactory outdoor sign for you within 3 to 15 days.
