Coroplast Source?

[JHinman]

The bottom of my TT is corrugated plastic, sometimes referred to as Coroplast.

Is this the same thing yard signs are made of, or are there different types of plastic used for this?

I am thinking of patching the underside of my trailer, and perhaps covering some areas the manufacturer left blank. If it is the same material, I should be able to get some from a local sign shop.

Thanks!

Yes it's the same, most common thickness for signs is 4 mm, I believe you can get up to 10mm. Double check your thickness.

You can probably also get it from any good plastics supplier, probably for less than a sign shop will charge. Around here (Milwaukee) I get plastic products like this from Midland Plastics. You're in a large city, so there should be something equivalent near you. They usually sell to the public, and will usually cut large sheets to smaller sizes for free or a minimal fee.

I would give check sign shops in your area. It’s been awhile (6 yrs), but I bought 4’ x 8’ sheets from one near me. When I called around for it, prices varied anywhere from $15 to $60 per sheet.
