Most backyard storage sheds today are made from either resin (plastic) or metal. Both can keep your mower, tools and garden gear dry, but they age differently, need different care and suit different budgets. Here is how they compare.
What is a resin shed?
Resin sheds are made from plastics such as high-density polyethylene (HDPE) or polypropylene. Better models use double-wall or multi-wall panels and a steel frame or steel reinforcement inside for extra strength. The panels are usually UV-protected so they do not fade or crack in the sun.
What is a metal shed?
Metal sheds are usually made from thin galvanized or coated steel panels on a steel frame. They are often the lowest-cost option per square foot, especially in larger sizes.
Resin vs metal at a glance
| Resin | Metal | |
|---|---|---|
| Rust | Will not rust | Can rust if the coating is scratched |
| Dents | Flexes and resists dents | Thin panels can dent |
| Maintenance | No painting or staining; just wash it | Touch up scratches to prevent rust |
| Condensation | Less prone to condensation | Can drip with condensation in cold weather |
| Floor | Many include a built-in resin floor | Floor kit often sold separately |
| Assembly | Panels snap or screw together; usually simpler | Many small screws; more time-consuming |
| Cost | Higher than basic metal | Usually lower upfront |
Pros and cons of resin sheds
- Pros: no rust or rot, low maintenance, attractive finishes, often include floors, windows and skylights, easier assembly.
- Cons: higher price than basic metal sheds, and they need a level, solid base to stay square.
Pros and cons of metal sheds
- Pros: low upfront cost, available in large sizes, fire-resistant.
- Cons: can rust and dent, may need a separate floor, more parts to assemble, and condensation can build up inside.
Which should you buy?
Choose resin if you want a shed that looks good for years with almost no upkeep, especially in wet or snowy climates. Choose metal if your main goal is the lowest price for a lot of space and you are happy to maintain it.
Pick the right size
- Small lean-to (around 6 x 5 ft): fits against a wall or fence for tools, garden supplies and bins. See this 6 x 5 ft resin lean-to shed.
- Mid-size (around 8 x 10 ft): room for a push mower, bikes, tools and seasonal items. See this 8 x 10 ft resin shed with floor.
- Large (around 11 x 11 ft): space for a riding mower or snow blower plus garden equipment. See this 11 x 11 ft steel-reinforced HDPE shed.
- Garage-size (around 11 x 21 ft): wide double doors for vehicles, tractors and workshops. See this 11 x 21 ft storage garage kit.
Tip: measure the biggest item you plan to store, including handles, and leave room to walk around it. Check door width as well as floor size.
Frequently asked questions
Do resin sheds need a foundation?
Yes. Any shed needs a flat, level base. Common options are a concrete slab, pavers or a level wood platform. A level base keeps doors aligned and helps the shed last.
How long do resin sheds last?
A good-quality resin shed with UV-protected panels can last many years, and many come with a 10-year limited warranty. Check the warranty on the model you choose.
Can a resin shed handle snow?
Many resin sheds are built with steel-reinforced roofs and list a snow-load rating. Clear heavy snow from the roof after big storms either way.
