Our sheds come standard with 5/8” OSB flooring on 24” centered floor joists. If you are storing anything heavy you will need to upgrade the floor. We offer 12” or 16” centered floor joist construction upgrades from our 24” standard centered floor joists. Also, we offer 5/8″ or 3/4″ pressure treated plywood flooring which is a stronger superior floor material than our standard 5/8″ OSB flooring. If you upgrade your floor and are storing an extreme weight we offer floor joist hangers which help reinforce the strength of the floor upgrades. If you won’t be going in the shed often and are simply storing patio furniture, a push mower and basic garden tools our standard floor will suffice.
