Our prefabricated metal buildings are built in one of several manufacturing facilities across the United States and then are delivered to the jobs site where they are installed. While we build smaller units, our line of prefabricated steel buildings start at 26' wide and can be as wide as 60' wide. We offer side heights up to 20' tall on units that are 40' to 60' wide and can build those units as long as you need. Read more at https://www.metalcarportsdirec....t.com/prefab-metal-b
