Syntex Industries offers high end tarps and roll tarp kits for dump trucks and truck boxes. All of our tarps are made of heavy duty 18 oz. vinyl material that is treated against UV rays and mildew. They are featured with welded seams for strength and waterproofing as well! Plus, all of our hardware is galvanized or aluminum, so it will not rust. We offer a two year limited warranty on all of our products.
