Flatbed trailers are commonly used to carry large heavy machinery or equipment of unusual shapes. Flatbeds are essential in the construction, manufacturing and agricultural industries. With no sides or roof, a flatbed allows for quick and easy loading of goods that would be unable to load in a Dry Van. A popular type of Flatbed trailer is the step deck or drop deck with approximately 2 feet of lower deck and low-profilewheels to accommodate taller loads, without hitting low bridges or tunnels.
