Due to their susceptibility to rust, steel storage units should be avoided. Among metal storage units, rust-free aluminum is usually the most sensible choice in siding. Metal siding is hardly the most visually appealing choice.
Move It Out - When organizing your shed, it's important to consider what you use it for and the climate you live in. Keep in mind, many sheds are there to protect your items from the elements, rarely are they insulated enough to protect against extreme cold or heat. If there is anything currently in your shed, such as paint or liquids, you'll want to move those to a place that is more temperature controlled. Additionally, any pet food or paper is surly asking for a visit from any pests in the area. Move them inside the house where you can ensure their quality.
