- Keep children and pets away from the assembly area to prevent accidents.
- Do not exceed the weight limit of 70kg/m² (approximately 150 lbs/sq.ft) for the roof. Excessive snow or debris accumulation must be cleared promptly.
- Wear appropriate safety gear, including gloves and eye protection, during assembly.
- Inspect all components for damage before assembly. Do not use damaged parts.
- Ensure the assembly area is clear of obstructions and level.
- In case of severe weather conditions (heavy snow, strong winds), consider disassembling the structure or taking additional precautions to secure it.

4. Setup and Assembly
Assembly of the COSIEST 12x25 FT 2-in-1 Carport Storage Shed requires careful attention to detail and adherence to the following steps. It is strongly recommended to have at least three people for assembly.
- Site Preparation: Choose a level, stable area for installation. Clear any debris, rocks, or vegetation. Ensure adequate space around the structure for assembly.
- Unpack and Organize: Carefully unpack all components and lay them out according to the parts diagram. Group similar parts together for easier access.
- Assemble Base Frame: Connect the horizontal and vertical base frame pipes using the provided connectors and fasteners. Ensure all connections are secure but do not fully tighten bolts until the entire frame is assembled.
- Erect Vertical Supports: Attach the vertical support pipes to the base frame. Gradually raise the structure, securing each vertical support. This step requires multiple people to hold the frame steady.
- Install Roof Frame: Connect the roof frame pipes to the vertical supports. Ensure the roof pitch is correctly oriented.
- Attach Roof Panels: Carefully lift and secure the galvanized steel roof panels to the roof frame using the designated fasteners. Overlap panels as instructed to ensure water resistance.
- Assemble Storage Section: Construct the enclosed storage section frame and attach the wall panels. Install the door assembly according to the specific instructions for that component.
- Final Tightening: Once the entire structure is assembled and aligned, systematically tighten all bolts and fasteners.
- Anchoring: Securely anchor the carport to the ground using the provided anchoring hardware. For concrete foundations, use expansion bolts. For soil, use ground stakes. Ensure anchors are driven deep enough to provide maximum stability.
Refer to the detailed assembly diagrams included in your packaging for specific component identification and step-by-step visual guidance. Do not deviate from the instructions.
5. Operating Instructions
The COSIEST 12x25 FT 2-in-1 Carport Storage Shed is designed for sheltering vehicles and providing secure storage. Follow these guidelines for optimal use:
- Vehicle Parking: Drive vehicles into the carport section carefully, ensuring adequate clearance on all sides. Avoid contact with the frame or roof panels.
- Storage Use: Utilize the enclosed storage section for tools, equipment, or other items. Ensure the door is securely closed and locked when not in use to protect contents from weather and theft.
- Weight Distribution: When storing items, distribute weight evenly within the storage section. Do not lean heavy objects against the walls or frame.
- Ventilation: If storing items that require ventilation, ensure the storage section is not completely sealed.
- Weather Conditions: In anticipation of heavy snow, high winds, or other severe weather, take extra precautions. Clear snow from the roof promptly to prevent exceeding the weight limit. Consider temporary bracing or additional anchoring in extreme wind conditions.
6. Maintenance
Regular maintenance will extend the lifespan of your COSIEST Carport Storage Shed and ensure its continued safety and functionality.
- Regular Inspection: Periodically inspect the entire structure for loose bolts, damaged panels, or signs of corrosion. Tighten any loose fasteners immediately.
- Cleaning: Clean the roof and panels regularly to remove dirt, leaves, and other debris. Use a mild soap solution and a soft brush or cloth. Avoid abrasive cleaners or harsh chemicals that could damage the finish.
- Snow Removal: During winter, promptly remove snow accumulation from the roof to prevent structural stress and potential collapse. Do not use sharp tools that could damage the roof panels.
- Anchoring Check: Verify that the anchoring system remains secure, especially after strong winds or heavy rain. Re-secure or replace anchors as needed.
- Corrosion Prevention: If any scratches or chips appear on the metal frame or panels, touch them up with rust-inhibiting paint to prevent corrosion.
- Door Maintenance: Lubricate door hinges and latches periodically to ensure smooth operation.
7. Troubleshooting
This section addresses common issues you might encounter with your carport storage shed.
| Problem | Possible Cause | Solution |
