Our 18 oz vinyl tarps are very thick with rust resistant brass grommets at corners and every 24”. These tarps are waterproof, and include UV, oil, acid, and grease resistance. These tarps would be great as an agricultural, industrial, truck, or construction cover. They also work well for roofing and athletic/recreational activities. Finished size approximately 3-5% or 6" shorter. Strong tarp, great for any heavy duty activity!
