Arrow is one of the country's leading brands of metal storage sheds. Most Arrow sheds are designed for simple do-it-yourself installation requiring only standard hand tools. It's possible to assemble a shed by yourself, but the work will go much quicker with a helper or two. For an optional foundation, Arrow recommends concrete or pressure-treated wood. With or without a foundation, it's a good idea to start with a subbase of 4 to 6 inches of compacted gravel, for a stable surface that drains well.
Lay out and fit together the rails and corners of the floor frame (do not fasten them yet). Set the wall posts into the slots of the floor rails. Set the door jambs in the same fashion. Fit the slots of the top rails and door rail over the ends of the wall posts, then slip the top corner pieces over the ends of the top rails.
Check the floor frame for squareness by measuring diagonally between opposing corners; the frame is square when the dimensions are equal. Prepare the ridge beam and secure the beam to the front and rear top rails, using the screws provided. Install the rafters with screws. Bend the tabs on the roof cross braces and set the tabbed ends into the rafter slots. Install the midwall channels in the same fashion. Attach the wall diagonal braces.
Assemble the halves of the gable ends and secure them to the front and rear top rails with screws. Slip each wall panel into the top rail channel, then snap the edges of the panel into the slots on the wall posts. Snap the corner panels into the slots on the corner wall posts. Join all neighbouring wall panels with the provided snap-on connectors.
Install the roof panels in the same fashion as the wall panels. Secure the roof trim over the bottom ends of the roof panels with screws. Inside the shed, fasten the wall posts to the top rails and floor rails with screws. Install the ramp at the bottom of the door opening. Assemble the door handle, then hang the doors using the preinstalled hinges.
Anchor the building, using the appropriate anchor kit for your type of foundation/installation. There are kits for anchoring into concrete slab foundations or into the surrounding ground.
Lightweight metal sheds can be damaged or moved by high winds. Always anchor a metal shed according to local building code requirements; check with your city's building department for recommendations. Always read and follow the detailed assembly instructions that come with the shed. While broad instructions will work for the basics of all sheds, some details may vary, depending on the model.
