Our 18×21 steel garage is great for storing one car or truck, with added space for heavy equipment.  Like all of our affordable metal buildings, this steel garage includes free shipping and installation.  There is an 8′ wide x 7′ tall garage door on the front of the building that can accommodate almost any car or truck.  You can customize this garage for anything you need, including adding an entry door or windows.  Choose from our wide selection of colors to find one that fits your style.

Metal Buildings Built to Last

Our carports and garages are designed to last a lifetime, with very little maintenance required.  Steel is more durable, less expensive, and requires less upkeep than other types of standard building materials.  We only use the highest quality galvanized steel on our metal building frames.  The roof and wall panels are heavy duty 29 gauge steel sheets.  We also strengthen the frame with extra bracing on the corners and center.  We guarantee that your garage will be free of leaks and other defects.

Easy Steel Garage Installation

We strive to make installation simple and easy.  All we require to install your steel garage is that you have a level installation site.  We can install our metal buildings on almost any surface, including concrete, asphalt, dirt, gravel, or even wood.  We recommend a concrete pad or cost saving footers for ease of installation, and we even provide concrete anchors at no extra charge.  Anchors for other surfaces are available upon request.  If you would like to install the structure yourself, any of our quality building designs can be purchased as a DIY building kit.  The kits are designed to be constructed using only common household tools, meaning you don’t have to be an engineer to build your new 18×21 garage!  Have questions? We have answers – call or chat with an advisor, or shop online to customize your own metal building today!
