A flatbed trailer is a type of open trailer used for transporting a wide variety of goods, equipment, and materials that do not require the protection of an enclosed space. Unlike enclosed trailers, flatbed trailers have a flat and open platform without sides or a roof, allowing for easy loading, unloading, and transportation of oversized or irregularly shaped items. They are commonly used in the transportation and logistics industry for carrying large, heavy, or bulky loads that cannot be accommodated in standard enclosed trailers.
