Metal sheds made from thin sheet metal covering (galvanized steel, aluminium, or corrugated iron) attached to a metal frame. Metal sheds are a good choice when long-term strength and resistance to fire, rot, or termites is desired. Some types of metal sheds that have thin walls are easily scratched, which may makes some types of thin metal sheds a poor choice for vandal-prone areas or for high-traffic activities such as small businesses. In cold climates, metal sheds with thin walls need to have snow cleared from the roof, because the thin metal may be damaged by a heavy accumulation of snow and ice.

Plastic shed kits utilising heavy moulded plastics such as PVC and polyethylene are more expensive than sheet metal sheds. PVC resins often have more resistance to denting and chipping than wood and tend to be more stable. Plastic shed kits sided with vinyl are typically among the least expensive types of shed construction.

Wooden sheds have a natural look that can blend in well with garden environments. Despite the strength of wood, over time it can decay, split, warp or become prone to mold and mildew, so wood sheds should be treated for protection. Wood sheds need regular maintenance, such as keeping plant matter and fragments from piling up beside the walls and on the roof, and periodically re-staining or varnishing the wood.

Vinyl sided sheds are built with standard wood framing construction and oriented strand board on the walls covered with standard vinyl siding. Vinyl-sided sheds never need to be painted, they are generally stronger than plastic or metal sheds, and are usually built to conform with the local building codes.
