are typically made of metal (steel, tin, or aluminum) and are modular in style in the USA, while remaining flat-roofed permanent structures in much of the rest of the world. The carport is considered to be an economical method of protecting cars from the weather and sun damage. The metal carports in USA can be divided into Regular, Boxed-Eave, and Vertical roof styles. They differ in the sturdiness and how the roof panels are oriented.
