Many metal garage kits come in a wide variety of sizes. Available heights often range from 8' to 12' to 16'. Widths are commonly available between 12' and 50'. Siding is usually available in both horizontal and vertical alignment. This is really just a matter of preference and taste. Of course, color matters to many people, and many companies offer different colors for both roofing material as well as siding. Other options to think about include electric door openers and windows. Some kits include these things and others make you purchase them separately. To learn more please check out our website.
