Outsunny Outdoor Storage Shed Dark Gray 11’×13′ Galvanized Steel

Clean lines, serious storage — the Outsunny 11 × 13 ft Outdoor Storage Shed in Dark Gray is a full-size galvanized steel structure built for backyards that demand both capacity and a refined, understated look. Constructed entirely from galvanized steel with a sleek Dark Gray painted finish, this shed delivers the inherent advantages of metal construction — fire resistance, zero rot, zero warping — without any of the maintenance demands of wood. The galvanized roof is fully waterproofed and features a sloped striped profile that efficiently channels rain and prevents standing water from accumulating on the surface. Four ventilation slots, two on the front wall and two on the rear, generate continuous cross-airflow through the interior, keeping humidity levels low and preventing the kind of moisture buildup that causes stored tools, equipment, and seasonal items to deteriorate. The neutral Dark Gray finish pairs with any outdoor setting and holds its color well against UV exposure and the elements.

With interior dimensions of 130″ W × 146.5″ D, this shed offers abundant room for lawn mowers, bicycles, power tools, garden supplies, pool accessories, patio furniture, and much more. The double sliding doors open to a combined width of 54.25 inches — a smart space-saving design that requires no swing clearance and makes moving large or awkward items in and out completely effortless. A built-in locking mechanism secures the doors when the shed is unattended (lock not included). The included foundation kit anchors the structure to any flat surface for immediate stability, and can be paired with wood boards to create a fully sealed floor base that keeps mud and groundwater away from stored belongings. Pre-cut and pre-drilled steel panels simplify the assembly process, though at least three adults are recommended to handle the panels safely during installation.
