Metal Sheds

A metal shed is the rot-proof, rodent-resistant alternative to wooden: galvanised steel or coated aluminium, no annual treatment, and a much faster build (most assemble in a half-day rather than the full weekend a wooden shed needs). The compromise is condensation. Warm air in summer hits cool metal and produces drips inside. The fix is roof venting and a vapour barrier under the floor, both standard on better units. Sizes follow the same 6x4 to 10x8 grid as wooden sheds, but the wall thickness varies. 0.4mm steel is the budget tier and dents under a hard knock; 0.5mm and 0.6mm are the longer-life builds. Aosom UK and Buy Sheds Direct between them stock 500+ metal sheds from £7 to £3,280; Cherry Lane Garden Centres covers the £100-£600 mid-bracket. Metal sheds suit gardens where the shed sits in shade, since heat builds inside on south-facing sites. The grid below filters by size, wall gauge, floor included and door type.
