When your storage demands are serious, the Keter Stronghold 10 × 11.5 ft Outdoor Storage Shed in Graphite delivers. Built with Keter’s EVOTECH™ composite material, the Stronghold delivers the rich, authentic look and feel of natural wood grain on the outside while offering the structural strength of an engineered resin-and-steel system on the inside. The deep Graphite finish resists UV fading, moisture damage, and seasonal wear without ever needing to be painted or sealed. Six oversized transom windows plus a full-length roof skylight flood the interior with natural light, making the Stronghold spacious enough to function as a workshop or hobby space, not just equipment storage. Realistic 3D roof shingles complete the look of a permanent structure. With 706.3 cubic feet of interior volume, the Stronghold 10×11.5 stores riding lawnmowers, multiple bicycles, motorcycles, ladders, ATVs, patio furniture, and a season’s worth of tools at once. The extra-wide 60-inch double doors and sloped threshold floor let a riding mower roll straight in. The heavy-duty floor includes 18 anchor points to bolt the shed to any foundation. Steel reinforcement throughout delivers wind resistance up to 90 mph and a snow load rating of 30 lbs per square foot, and built-in ventilation on both sides keeps moisture, mold, and mildew away from stored belongings.
