Source for legitimately heavy-duty shade tarps?

[Gern Blanston]

We need to replace some older 20'x20' black/gray shade tarps for our conduit-framed garages. Despite retailers insisting their tarps are heavy-duty, they're often junky and last just a year or two. Can anyone recommend a supplier that sells the noticeably thicker tarps with the heavy grommets? We need them relatively quickly, but happy to pay more for quality.

I have had really good luck with tarps purchased from a place I found online....I don't think I can just blurt out the name of the place, but here are a couple of hints.
the first word rhymes with farps
the second word is + spelled out

they have a lot of different kinds to choose from

Thanks so much! I will check them out. No, I hope I'm not flouting any rules here by asking for retail recommendations. I'd just like to keep from prematurely sending tarps to the landfill.

You can also find repurposed billboard vinyl online, longer lasting, stronger and heavier than any woven tarps that I've seen... It's also designed to resist uv and not start flaking and making dust after a few months in the sun.
