PEKGRIL 24" x 36" Corrugated Plastic Poster Boards — 4 Pack
Product description
Each package contains four corrugated plastic panels measuring 24 inches by 36 inches with a 4 mm thickness. The boards are manufactured from 100% high-density polypropylene, giving them a lightweight feel while maintaining weather resistance and durability.
Both faces of each sheet are smooth and blank, making them suitable for painting, lettering, applying vinyl, gluing photos, or other decorative treatments. The even surface works well for permanent markers, paint, and adhesive materials.
These panels are waterproof and offer resistance to sun exposure, so they can be used outdoors for events, yard signage, and displays without immediate degradation. They’re also reusable for multiple occasions when handled properly.
Because they are lightweight, the sheets are easy to cut with a utility knife, trim to custom sizes, fold for temporary mounts, or shape to fit A-frame stands, H-stakes, or custom frames. They can be modified with grommets or holes for hanging or anchored with wire stakes for lawn placement.
Typical uses include real estate signs, yard sale signs, protest or event placards, photo displays, art projects, and DIY crafts. While sturdy for many applications, avoid exposing the boards to sustained high heat or direct sunlight for long periods to prevent warping.

- Smooth, double-sided surfaces for writing and graphics

VerdictThese 24" x 36" corrugated plastic panels offer a durable, reusable surface for signs, art, and DIY builds. At 4 mm thickness and constructed from high-density polypropylene, they resist water and sun exposure while remaining light enough to trim, fold, and install with common holders or stakes. They’re excellent for temporary outdoor use and crafting, though prolonged direct heat can cause warpin

Built to endure
These panels feel extremely durable and are a generous size. Lettering, painting, and drawing on them is enjoyable. They arrived intact and the four-pack is great value. Sturdy — I expect years of use and recommend them.

Too flexible for my purpose
Nice looking, but too soft for what I needed. I used them as dividers in a Pelican case and they didn’t hold their shape for that application.

Perfect for a photo display
Good quality boards. I used them to mount photos for my father-in-law’s memorial and they worked perfectly.

Did the job
Performs well for basic tasks, but avoid leaving it in direct sun or near heat sources since it can warp.

Versatile and dependable material
Good quality and value. Cuts easily with a box cutter and accepts permanent markers and vinyl. Lightweight for carrying at parades or rallies. I recommend adding grommets when hanging to extend life. Weather resistant and works with wire stakes; orienting signs horizontally helps resist wind. Overall, solid choice.
