Keter Stronghold 10×11.5 ft Graphite Resin Outdoor Storage Shed

When your storage demands are serious, you need a shed that lives up to its name — and the Keter Stronghold 10 × 11.5 ft Outdoor Storage Shed in Graphite does exactly that. Built with Keter’s innovative EVOTECH™ composite material, the Stronghold delivers the rich, authentic look and feel of natural wood grain on the outside while offering all the structural strength of an engineered resin-and-steel system on the inside. The deep Graphite finish is bold and contemporary, resisting UV fading, moisture damage, and the wear of every season without ever needing to be painted or sealed. Six oversized transom windows — three across the front, three across the back — plus a full-length roof skylight flood the interior with natural light from every angle, making the Stronghold spacious enough to function as a proper workshop or hobby space, not just a place to pile equipment. Realistic 3D roof shingles complete the aesthetic, giving the shed the polished look of a permanent structure that actually adds value to your property. With a massive 706.3 cubic feet of interior volume, the Stronghold 10×11.5 comfortably stores riding lawnmowers, multiple bicycles, motorcycles, ladders, ATVs, full sets of patio furniture, and an entire season’s worth of tools — all at the same time. The extra-wide double doors measure a full 60 inches across, wide enough to roll a riding mower straight in without maneuvering, and the sloped threshold floor means no lifting required. The heavy-duty floor supports even the heaviest equipment and includes 18 anchor points to permanently bolt the shed to any concrete, paver, or wooden foundation. Steel reinforcement throughout the double-walled panels delivers wind resistance up to 90 mph and a snow load rating of 30 lbs per square foot, while built-in ventilation on both sides keeps moisture, mold, and mildew away from stored belongings year-round. A padlock-ready latch with a 3-point locking system keeps everything locked up tight. An optional Keter shelving kit is available separately to maximize wall storage even further. ▣ Specifications Specification Detail SKU 1319 GTIN 3253924869896 Color / Finish Graphite — EVOTECH™ wood-look resin composite, UV-resistant Shed Size 10 ft × 11.5 ft (~115 sq ft floor area) Exterior Dimensions 120.1″ W × 137.8″ D × 98.8″ H Interior Dimensions 114.9″ W × 128.3″ D × 92.5″ H Storage Capacity 706.3 cubic feet Wall Technology EVOTECH™ double-walled resin composite with steel reinforcement Roof Style Classic peak (gable) roof — steel reinforced, 3D shingle design Natural Light Full-length skylight + 6 transom windows (3 front, 3 rear) Ventilation Built-in two-sided ventilation — prevents mold and mildew Door Width 60″ (152.5 cm) extra-wide double doors with sloped threshold Snow Load Capacity 30 lbs per sq ft Wind Resistance Up to 90 mph Security 3-point locking system — padlock compatible (lock not included) Floor Heavy-duty floor included — 18 anchor points for ground fastening Optional Accessory Compatible with Keter Shelving Kit (sold separately) Assembly Shed kit — basic tools only, instructions included
