1. Site Preparation
Select a flat, level, and well-drained area for your shed. It is recommended to measure the foundation size first to ensure proper fit. Clear any debris, rocks, or vegetation from the chosen site.

3. Wall Panel Installation
Attach the galvanized steel wall panels to the assembled frame. Pay close attention to the orientation of each panel. Secure them using the provided screws and fasteners. Ensure panels are aligned to prevent gaps.
4. Roof Assembly
Install the sloped roof panels. The sloped design is crucial for preventing water and snow accumulation. Ensure all roof panels are securely fastened and overlap correctly to maintain weather resistance.

Maintenance
- Cleaning: Clean the shed exterior periodically with mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the painted galvanized steel finish.
- Fastener Check: Regularly inspect all screws, bolts, and connections. Re-tighten any loose fasteners to ensure the structural integrity and stability of the shed.
- Drainage: Ensure the area around the shed remains clear of debris to allow for proper water drainage from the sloped roof.
- Ventilation: Keep the air vents clear of obstructions to maintain proper airflow and prevent moisture buildup inside the shed.
- Rust Prevention: Although made from rust-resistant galvanized steel, promptly address any scratches or chips in the paint to prevent potential rust formation.
