2. Safety Information
Important Safety Precautions:
- Always consult local building codes and authorities before commencing installation. Compliance with local regulations is essential for safety and legality.
- Ensure the garage is installed promptly after delivery. Leaving components unsecured for extended periods can pose safety risks.
- Anchor the structure firmly to the ground. Proper anchoring is critical for stability and safety, especially in adverse weather conditions or when storing heavy items like vehicles or RVs.
- Use appropriate personal protective equipment (PPE) during assembly, including gloves, safety glasses, and sturdy footwear.
- Do not attempt to assemble the structure alone. A minimum of two people is recommended for safe and efficient installation.
- Keep children and pets away from the construction area.
3. Setup and Assembly
3.1 Site Preparation
Before assembly, select a level and stable site. The structure is compatible with various ground surfaces, including concrete slabs, asphalt foundations, level ground, floating slabs, and trench footings. Ensure the chosen location provides adequate drainage and clearance.

3.2 Unpacking and Inventory
The garage ships in two wooden crates. Upon delivery, inspect the crates for any damage. A forklift or equivalent heavy lifting equipment is required for unloading due to the weight and size of the crates. Verify all components against the packing list provided in the box. An additional 5% extra hardware is included to account for any minor losses during assembly.

3.3 Assembly Process
The KoreJetMetal barn garage is designed for easy assembly with pre-drilled parts and smart-connect brackets, requiring no welding. Follow the clear, step-by-step instructions included in your package. Ensure all connections are secure and tightened appropriately.
- Frame Assembly: Begin by assembling the heavy-duty 14-gauge and 16-gauge steel frame components. The frame utilizes 2.3-inch and 4.3-inch square tubes for structural integrity.
- Panel Installation: Attach the 26-gauge metal panels to the assembled frame. Ensure panels overlap correctly for weather resistance.
- Door Installation: Install the three roll-up doors and the side entry door according to the instructions. Ensure they operate smoothly and securely.
- Anchoring: Use the included 1/2-inch x 6-inch concrete anchors to firmly secure the structure to your chosen foundation. Proper anchoring is crucial for stability and wind resistance.

4. Operating Instructions
4.1 Roll-Up Doors
The garage is equipped with three large roll-up doors, each measuring approximately 98.4 inches in width. These doors are designed for easy manual operation to allow access for vehicles, large equipment, or other stored items. To open, lift the door evenly from the bottom edge. To close, pull the door down smoothly until it is fully seated.

5. Maintenance
Regular maintenance will extend the lifespan and ensure the continued performance of your metal barn garage.
- Cleaning: Periodically clean the exterior panels with mild soap and water to remove dirt, dust, and debris. Avoid abrasive cleaners or harsh chemicals that could damage the powder-coated finish.
- Inspection: Regularly inspect the frame, panels, and anchors for any signs of wear, corrosion, or loosening. Tighten any loose bolts or fasteners.
- Door Operation: Keep the tracks and moving parts of the roll-up doors clean and free of obstructions. Lubricate hinges and rollers annually with a silicone-based lubricant to ensure smooth operation.
- Drainage: Ensure the area around the base of the garage remains clear of debris to allow for proper water drainage and prevent moisture buildup against the structure.
- Snow and Wind: While designed for 35 PSF snow load and 100 MPH wind resistance, it is advisable to clear heavy snow accumulation from the roof and ensure all doors are securely closed during high winds.
