Flatbed trailer is an open-deck transportation platform defined by its lack of sides and roof, enabling superior loading access. Its primary application is hauling oversized, heavy, or irregular cargo like construction equipment, machinery, steel coils, and wind turbine blades across industries . Common types include standard-length trailers, extendable flats for adjustable deck size, and specialized lowboy trailers for extra-tall loads, all designed for maximum versatility and logistical efficiency.
