How to Assemble Metal Sheds
A metal is a cheap and easy way to provide for all your outside storage needs. Often sold in pre-fabricated kits, a metal shed comes ready to assemble from the manufacturer and can be put together, usually within a weekend, with a few common tools and two to three people. When assembling your metal shed, always follow the manufacturer’s instructions, however, most are built in a similar fashion.
Before You Build
Make sure you have all appropriate building permits to begin work.
Choose a site that is large enough for the shed, as well as large enough to provide access when building.
Thoroughly read over the manufacturer’s instructions before you begin.
Keep the parts well laid out, as they are often packaged in building order.
Laying the Foundation
Select a level site for building your shed. If it is not level, you will need to level it before you begin.
Dig out about 6 inches of soil for your concrete slab.
Fill your hole with 4-inches of compacted gravel.
Lay a layer of 6mil plastic over the gravel.
Construct a 2-inch-by-4-inch frame to hold your concrete slab.
Pour your concrete and level the slab. Allow 24-48 hours to dry.
Building the Shed Frame
Lay out the floor rails following the manufacturer’s plans, making sure to orient the door rail in the direction you would like it to face.
Add the support posts by attaching them into the floor frame. Do not screw the posts into the floor or screw down the frame just yet.
Add the doorjambs. Slide the door jambs into the floor railing making sure they are facing the proper direction.
Place the top rails onto the frame by connecting them to the shed posts. Make sure that the shed frame is still square.
Attach the ridge beam and rafters to the shed frame. Screw the rafters into the frame as directed by the manufacturer.
If supplied, secure the mid wall channel supports to the shed frame and secure with screws.
Adding the Shed Panels and Finishing the Shed
If included, add the gables to the shed by screwing them into rafters and top rails.
Slide the wall panels into the frame posts. To do this, raise the top frame rail slightly, position the panel in the frame and snap into place along the frame posts. Once all of the panels are in place, pull the top rails back down, locking in the wall panels.
If supplied, snap the corner panels and panel connectors into place in the same fashion as you added the wall panels.
Add the roof panels by sliding them in between the rafters and the ridge beam. Once the roof has been installed, slide the roof connectors in between the roof panels.
Once all the wall and roof panels have been added, screw the shed frame together with the supplied screws.
Attach the door by sliding it on to the hinges on the doorjamb.
