4. Setup and Assembly
Follow these steps for the proper assembly of your storage shed. Refer to the detailed diagrams in the accompanying video for visual guidance.
4.1 Foundation Preparation
Ensure the ground is level and provides a stable base for the shed. A recommended space of 3700mm x 4500mm is ideal for the 10x14 FT model.
4.2 Underframe Mounting
Assemble the base frame using the designated K810-1, K810-1R, K810-2, K812-2R, and T-F parts. Secure all connections with F1 screws as indicated in the video. Ensure all corners are tightly fastened to form a rigid base.
4.3 Wall Framing Installation
Attach the wall panels (W5-CD) to the underframe using F1 screws. Connect the top wall frames (K810-3, K810-3L) to the wall panels, securing them with F1 screws. Ensure all panels are aligned and firmly attached to the base and top frames.
4.4 Wall Mounting
Install the remaining wall panels (W5-D) along the sides, securing them to the frame with F1 and F2 screws. Ensure each panel overlaps correctly and is fastened securely to maintain structural integrity and weather resistance.
4.5 Door Frame Installation
Mount the door frame components (W5-CD, W5-D) at the designated entrance area. Secure these parts with F1 and F2 screws, ensuring the frame is plumb and square for proper door operation.
4.6 Roof Support Installation
Install the roof support beams (K810-3, UAD) and connect them to the top wall frames using F1 and F2 screws. Attach the roof support panels (K1014-5L, K1014-5R) to the beams, securing them with F1 screws. Ensure all connections are tight to support the roof structure.
4.7 Roof Panel Installation
Carefully place the roof panels (K1014-7L, K1014-7M, K1014-7R, K1012-7MM) onto the roof support structure. Make sure that each board overlaps exactly where it meets and that the screw holes are aligned. Secure each panel immediately after placement with F1 and V2 screws to ensure screws remain accessible. Do not wait until all panels are placed, as this will make some screw holes unreachable. Install the roof ridge caps (K812-10, K812-10M) and corner caps (GC, GE) using F1, F2, and F4 screws as shown.
4.8 Door Mounting
Attach the door panels (W5-KD, W2-HLD, W2-HRD) to the door frame using the provided hinges (DH) and F3 screws. Install the door braces (DBD) and the door handle (GL) with F1 and F2 screws. Ensure the doors open and close smoothly and the locking mechanism functions correctly.

5. Operating Instructions
Your Sannwsg 10x14 FT Outdoor Metal Storage Shed is designed for straightforward operation.
- Door Operation: The shed features a single hinged, lockable door. To open, unlock the door and pull the handle. To close, push the door firmly until it latches, then lock it for security.
- Ventilation: The shed is equipped with vents to promote air circulation and prevent moisture buildup. Ensure these vents are not obstructed to maintain optimal internal conditions.
- Lighting: Utilize the included solar light and magnetic work light for illumination inside the shed as needed. The solar light charges during the day and provides ambient lighting, while the magnetic work light offers portable, directed illumination.
6. Maintenance
Regular maintenance will extend the lifespan of your Sannwsg storage shed.
- Cleaning: Clean the exterior of the shed periodically with mild soap and water. Avoid abrasive cleaners or harsh chemicals that could damage the electro-galvanized steel and paint treatment.
- Inspection: Annually inspect all screws, bolts, and connections to ensure they remain tight. Re-tighten any loose fasteners.
- Drainage: Ensure the area around the shed is clear of debris to allow for proper water drainage from the sloped roof. This helps prevent water accumulation and potential damage.
- Rust Prevention: The metal garden storage shed adopts an electro-galvanized steel process and paint treatment for rust resistance. However, if any scratches or chips occur, touch up with appropriate rust-inhibiting paint to prevent corrosion.
7. Troubleshooting
If you encounter any issues with your Sannwsg storage shed, refer to the following common solutions:
- Difficulty with Door Closure: Check if the shed is level. An uneven foundation can cause doors to misalign. Adjust the foundation as necessary. Inspect hinges for any obstructions or damage.
- Water Leakage: Ensure all roof panels are correctly overlapped and all screws are securely fastened. Apply a silicone sealant to any gaps or seams if necessary, particularly around the base and roof edges.
- Loose Panels: Regularly check and tighten all F1 and F2 screws on wall and roof panels. Over time, vibrations or weather changes can cause fasteners to loosen.
- Missing Parts: If your shipment appears incomplete, contact customer support directly. The shed is shipped in two boxes, which may arrive on different days.
