Our heavy-duty canvas tarps are made from 100% Cotton, talk about a sustainable product! Canvas is great for protecting anything that needs to release moisture and heat. We do not recommend canvas tarps for over-the-road hauling, try one of our Heavy Duty Vinyl Tarps.
We use the very best thread from Champion Threads in Gastonia, NC. Polyester thread is the most versatile choice for industrial sewing. With the strength of nylon plus UV and mildew resistance, this construction will certainly keep our tarps protecting you through the heaviest of winds and rain.


Given its durability, this component will certainly outlive every other part of the tarp. Now that’s saying something!

We insert rust-proof #4 brass grommets every 1′- 2′ that has an ID of 1/2″. Our panels are double chain stitched together with rot-resistant thread. All hems are 1-1/2″ flat hems and double lock stitched for the best durability. We use Canvak on all of our canvas tarps for the best in water, mold, and mildew resistance. This makes our tarps 18oz after treatment. Canvas is breathable to let moisture out and most importantly keep your valuables dry.
This Heavy Duty Canvas tarp has many uses around the home, construction site, farm or wherever you need to keep valuables covered. With Old School construction and reliability, it’s hard to beat a Tarp Nation canvas tarp.
