If you have a DuraMax 10x13 foot shed, this foundation allows you to eliminate the necessity of a concrete foundation for your shed. With this steel frame foundation, you just need to find a level area to place your shed, and you can have your shed easily installed. Once you put the metal foundation together, you can fill it with concrete in order to have a smooth floor, or you can put some type of wood over it. This added protection can increase the stability and longevity of your shed and allow you to get more use out of it than ever before.
