Temporary Material - 6-12 Month Lifespan
Corrugated plastic is designed for temporary outdoor use (6-12 months). UV exposure will cause brittleness and fading over time. For permanent outdoor signage or long-term applications, consider our UV-protected polycarbonate or acrylic sheets.
Frequently Asked Questions
How long do corrugated plastic signs last outdoors?
Twinwall polypropylene typically lasts 6-12 months outdoors before UV exposure causes brittleness, warping, or fading. This makes it perfect for temporary applications like political campaigns, seasonal real estate signs, or short-term events. For permanent outdoor signage, consider UV-protected materials like polycarbonate or acrylic.
What's the difference between 4mm and 10mm corrugated plastic?
4mm (0.157") is the standard thickness for yard signs, real estate signs, and lightweight applications - it's easier to cut and more economical. 10mm (0.390") is heavier-duty with greater rigidity, better for larger signs, construction site signage, or applications requiring extra durability. Both last 6-12 months outdoors.
Can I print on twinwall polypropylene?
Yes, white twinwall polypropylene is excellent for printing. It accepts screen printing, digital UV printing, and vinyl graphics. The smooth white surface provides vibrant colors and sharp text, making it the standard material for yard signs, political signs, and retail displays requiring custom graphics.
How do I install corrugated plastic signs?
Corrugated plastic signs install easily using H-stakes (wire stakes) pushed into the ground for yard signs, or with zip ties, screws, or adhesive for other applications. Cut to size with a utility knife and pre-drill holes if using screws. The lightweight material is simple to transport and install without special tools.
