Our shed floors start with 4x4 foundation runners (AKA skids) that are pressure treated and ready for ground contact with a .60 lumber retention rating. The number of runners depends on the width of the shed.

Number of runners by width:
  6' wide shed - 2 runners
  8' wide shed - 3 runners
  10' wide shed - 5 runners
  12' wide shed - 5 runners
  14' wide shed - 7 runners

These runners are not included with the 2x8 Floor Joists option due to their ability to lift the shed floor all on their own. This if for airflow purposes.

NOTE: Numbers displayed without measurement are nominal.
