Looking to assemble an Arrow or Scotts metal storage shed? Here’s a simple yet practical step-by-step checklist to get you going smoothly.
Plan Your Project:
Location/Permits/Setbacks/Size/Design/Foundation
-
Measure the space and decide on the shed size and style. Measure what you want to store in your shed and make sure it will not only fit inside, but will fit through the shed doors.
-
Check local building codes and permits.
-
Choose a flat, level location with good drainage. If a level space is not available, ensure it’s in an area where you can build a level base.
-
For the smoothest setup pick a day that’s dry and not windy.
Shed Assembly:
Step 1: Gather Your Tools and Inventory Your Kit
What you’ll need:
- Drill or screwdriver
- Clamps
- Tape measure
- Level
- Ladder
- Safety gloves and goggles
Open your metal shed kit and verify all parts are present. Follow the instruction manual exactly — skipping ahead can cost time later.
Step 2: Build or Prepare the Base
-
Build a level base (concrete, timber, or pavers).
-
Assemble the shed's perimeter base frame (usually included with the shed).
-
*Install the floor frame kit inside the perimeter base frame.
-
Secure the floor frame kit according to the manual.
-
Make sure everything is square and level before proceeding.
Step 3: Assemble the Shed Frame
-
Assemble wall frames, corner posts, and roof trusses.
-
Keep checking for square corners and level edges.
Step 4: Install Wall Panels
-
Start with one corner and work your way around.
-
Overlap panels as instructed.
-
Fasten panels securely but don't overtighten (this can warp the metal).
Step 5: Assemble and Attach the Roof
-
Attach roof beams or trusses.
-
Install roof panels starting from one side.
-
Use all provided fasteners and weatherproof washers.
Step 6: Hang the Doors
-
Assemble and install doors, hinges, handles, and any locks.
Step 7: Anchor the Shed
-
Anchor the shed to your base using anchor bolts or screws.
-
Seal any gaps with silicone or metal sealant to make it weather resistant.
Step 8: Final Touches
-
Check the entire shed for alignment and tighten all screws.
-
If you used a floor frame kit, add the plywood floor.
-
Clean your workspace and enjoy your new shed!
Learning how to assemble a metal shed doesn’t require a contractor — just a solid plan, the right tools, and a little patience. If you’re a DIY homeowner looking to protect tools, bikes, or seasonal gear, building your own metal storage shed is a practical weekend project with long-term rewards.
Take it one step at a time, don’t rush the prep work, and you’ll end up with a solid structure you can rely on for years to come — and the satisfaction of saying, “Yep, I built that.”
Do I Need a Floor Frame Kit?
A floor frame kit keeps your metal shed square during assembly by tying the base together, preventing twisting for proper wall and roof alignment. It provides a level base for a wood floor, adds stability, and raises the shed off the ground to protect against moisture, pests, and rust. Whether you need one depends on your base setup and long-term shed performance goals.
When You DO Need a Floor Frame Kit
-
If you don’t have a concrete slab, wood, or paver foundation.
-
If you’re building the shed directly on grass, dirt, or gravel.
-
If you want to install a wooden floor inside the shed.
-
If the shed kit specifically says "floor frame kit recommended" for stability.
When You MIGHT NOT Need One
-
If you already have a poured concrete slab (best option).
-
If you’re using large pavers or a pre-leveled deck base.
-
Some people skip it and just anchor directly to the base, but this can make the shed less rigid and may cause issues if the ground shifts.
