Strong, Affordable Protection
This Metal Garage is an outstanding way to protect your car or truck. It is built with a boxed eave roof and provides 252 square feet of storage space. The 12×21 garage provides completely enclosed storage space that is sure to protect your valuable vehicles and equipment for years to come. Total dimensions are 12′ wide by 21′ long by 10′ tall, and there is a roll-up garage door on the front of the building. All of our durable metal buildings are manufactured with top quality galvanized steel framing and roofing panels.

The boxed eave roof looks great, without sacrificing any quality. The roof has angled corners with overhangs on the sides. The roof panels, wall panels, and building trim can be ordered with as many colors as you need, adding your own personal touch to the structure. Whatever your building needs may be, our engineers are up to the challenge.

As long as you have a level building site, we will install your new metal garage in no time. We can install your building on almost any surface, including asphalt, gravel, or dirt (pictured). However, we recommend a concrete foundation for the best long term performance of your 12×21 garage. We provide concrete-specific anchors at no extra cost. We also include engineered foundation drawings to show how to set up your building site for installation. Pricing for our structures varies based on your geographic location, as well as your county’s local building codes and loadings. Be sure to let us know if you have any unique requirements for installation, and we will be sure to accommodate your needs.
