A metal garage is a good option for a place to securely store your vehicle and protect it from the elements. This storage structure can also house power tools and gardening items. Using a prefabricated kit can make this home improvement job a simple one.

Step 1 - Apply for Building Permits

Contact your local government office. Speak to a building inspection officer about your plans. Apply for the necessary permits to build your metal garage. This job will take at least a full day to complete.

Step 2 - Safety

Put on your protective eyewear, work gloves, and work boots before you begin to work. You will need the help of at least one person. Be careful working with any power tools and maneuvering yourself up and down the ladder.

Step 3 - Determine a Location for the Garage

Determine the best place for situating your new garage. You will need an area of land that drains well and is level.

Step 4 - Lay the Foundation

You will need a concrete slab foundation for your garage. If this job is difficult for you, contact a contractor to lay the concrete. If you choose to do the work yourself, you will need to lay the foundation two weeks before you begin to erect the garage. Build a frame for the concrete with the lumber and L brackets. Read the instructions provided by the manufacturer of the concrete. Mix the concrete and pour it into the frame. Allow the concrete at least two days to cure completely.

Step 5 - Read the Manufacturer Instructions

Be sure to read through all of the instructions provided by the manufacturer before you begin to work on the metal garage. Check to be sure you have all of the parts that are supposed to be in the kit.

Step 6 - Separate the Parts

Separate all of the metal garage kit parts into the frame members, the sides, the roof, the doors, and the hardware.

Step 7 - Assemble the Frame

Use your power drill, pliers, and wrench to assemble the garage frame. Begin at one corner of the frame. Align the holes in the frame. Use the bolts to secure the frame parts together. Assemble the roof frame.

Step 8 - Attach the Panels

Secure the panels to the frame. Position each panel, one at a time. Secure the panels with screws.

Step 9 - Attach the Roof Panels

Use the necessary hardware to attach the metal doors to the garage. Be sure they fit properly and they open and close securely. Attach any necessary handle hardware to the doors.
