Step deck trucks, like flatbed trucks, feature an open, level surface for carrying cargo. The key difference is that step deck trucks have a lower deck height, sitting closer to the ground than flatbeds. While flatbed trailers are typically about 60 inches above the ground, step deck trailers are even lower, making them ideal for transporting taller loads—those over 8 feet in height—that would not fit on a standard flatbed. This lower height helps avoid potential hazards, such as bridge clearances.

Step deck trailers have two deck levels—an upper and a lower—and are equipped with ramps for easy loading and unloading. Their closer-to-the-ground design also makes them safer for forklift operations during the unloading process.
