- Panel Installation: Attach the metal panels to the frame. Ensure panels are correctly oriented and securely fastened. The shed features galvanized steel panels for durability.
- Door and Window Installation: Install the main double doors, side entry door, and windows. Ensure all doors operate smoothly and securely latch.
- Roof Installation: Install the sloped roof panels, ensuring proper overlap and sealing to prevent water ingress.

6. Maintenance
Regular maintenance will extend the lifespan and preserve the appearance of your shed.
- Cleaning: Clean the exterior panels periodically with mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the powder coating.
- Fastener Check: Annually inspect all bolts, screws, and fasteners to ensure they are tight. Re-tighten as necessary.
- Drainage: Ensure the area around the shed is clear of debris to allow for proper water drainage from the sloped roof.
- Snow Removal: While the shed has an 11-inch snow load capacity, heavy or prolonged snow accumulation should be cleared to prevent excessive stress on the structure.

7. Troubleshooting
If you encounter issues with your shed, consider the following common solutions:
- Misaligned Holes: During assembly, if holes do not align perfectly, slightly loosen surrounding fasteners to allow for adjustment. Re-tighten once aligned.
- Door Operation: If doors stick or do not close properly, check for obstructions in the tracks or hinges. Ensure the shed is on a level surface, as an uneven foundation can affect door alignment.
- Water Leaks: Inspect roof seams and panel overlaps for proper sealing. Ensure all fasteners are tight.
