This laminated tarp is ideal for industrial and construction sites as well as cargo hauling. The white vinyl tarp is manufactured from a high-density 13 oz., 18 mil PVC material that is both waterproof and UV resistant. Grommets are strategically positioned along all four edges that also feature double-stitched hems and heat-sealed seams, making it a cinch to tie-down and protect cargo for easy transport. Tarp Surplus' vinyl tarps also do a standout job warding off grease, oil, mildew and acid.
