This 20 ft. by 30 ft. white polyethylene tarp from Core Tarps is a super heavy duty cover built for the outdoor and rural jobs that come up around a house, hobby farm, ranch, shop, or trailer. Use it to protect equipment from the weather, haul materials in a truck bed, cover firewood and hay, shield a roof until repairs are scheduled, or set up a quick canopy or ground sheet on the jobsite. Construction is woven 100 percent virgin polyethylene at 16 by 16 weave count, laminated on both sides, finished at 305 GSM, and rated at 20 mil thickness. Edges are double-stitched and rope-reinforced, with aluminum grommets set every 18 inches so tie-down with bungee cords, rope, or straps is secure on any side. The cover is fully waterproof, UV stabilized to slow sun fade, and treated for mildew resistance on both sides, so it holds up under rain, snow, sun, and damp storage. Sold at the finished hemmed size, so the 20 ft. by 30 ft. label dimension is what actually comes out of the bag, not the pre-cut measurement. Care is simple: hose off mud or debris, allow to air dry, and refold along the original creases for shelf or truck-cab storage. Backed by a 30 day Core Tarps manufacturer warranty against defects in materials and workmanship.
