There are a number of materials that manufacturers use to construct storage sheds. There is a wide range in durability and quality in these various products. Many use OSB or particle board in their flooring and siding because it is less expensive than other products and they just don’t point this out to their customers as they are presenting their product. Many customers don’t really think about this, they are just looking at price.
Some manufacturers will use a coated OSB, which they will say is as good as pressure treated plywood. This is really not the case, as scratches in the coating can lead to water retention in the OSB. Some use non pressure treated plywood in their flooring and siding, which is better than OSB, but still will absorb moisture and eventually cause problems in with the wood. The best solution is to use pressure treating materials in the flooring and siding. This gives you the protection you need in a storage building. It will resist moisture and give you a shed that should last a lifetime. Our Storage Building Sheds New Bern NC use all pressure treated materials in our flooring system and carries a lifetime warranty to back it up.

So, don’t be fooled by hollow promises from lesser quality products, Go Graceland and get the peace of mind of knowing that your shed is build of the best pressure treated materials and you don’t have to pay more to get the best.
