• Metal sheds are a relatively inexpensive way to store tools and other lawn equipment. They are also fairly simple to put together, as long as you follow the directions, and are usually set up in small areas of the yard. But metal sheds do have their share of issues that you must deal with, depending on your climate, and certain items that are better off not stored inside a metal shed.
  
  

Rust

• No matter what kind of protection or coating is on a metal building, eventually the metal will rust. It might present around drill holes or screws, metal edges that have become scratched or somewhere else, but it nearly always happens. The rust grows and spreads over time if not taken care of with a bit of sanding and application of a rust stopper. If left unchecked, the rust can create holes in the shed, leaks or weak spots.
  
  

Heat

• Metal buildings get hot and turn into an oven for whatever is inside. Due to this, you must take care about what you store inside a metal building. Don't store liquids that are under pressure or that can combust at high temperatures in a metal shed because there is no way to regulate the heat during summer months.
  
  

Condensation

• In the cooler months of the year, a metal building can get quite cold and the metal itself will hold the cold. As the sun starts to hit the metal later in the day and warm the outside of the metal, it can create condensation on the inside and outside of the building, which can lead to water damage on items stored inside the metal shed and increase the chances of rust.
