What happens here

Begin by laying out the 4x4 pressure-treated skids on the ground, ensuring they are properly spaced to support the shed. Next, place the 2x4 floor joists perpendicular to the skids. When positioning the joists, crown them (orient them so the natural bend faces upwards) to minimize sagging. For a 4-foot span, 2x4s are adequate, but for wider spans, consider using 2x6 joists for increased strength. Secure the joists to the skids using a nail gun and galvanized nails, which are essential for pressure-treated lumber to prevent corrosion.

Goal: Construct the shed's floor frame

Tools and materials

  • 2x4 Floor Joists — Constructing the main support for the shed floor
  • 4x4 Pressure-Treated Skids — Creating the base foundation for the shed floor
  • Galvanized Nails — Securing pressure-treated lumber
  • Nail Gun Milwaukee FUEL — Fastening joists to skids
  • Tape Measure — Measuring spacing and joist lengths

Let's get started. Start by laying out your 4x4 skids. And then you'll put your joists on top of that. You can check the span chart table to see which size you need to use. Here I am placing the crown of the joist facing upwards. I used 2x4s on a 4 ft span. Anything larger than that, you'll probably want to use a 2x6. You can do your layout on 12, 16 or 24 inch centers. I would say 16 is fine, but if you want it to be very strong , you can choose a center of 12. Nail all of these joists to the skid and be sure to
