The Utility 4000AE Aluminum and Steel Combo Flatbed features a patent-pending crossmember system that uses a combination of both 3" and 4" deep aluminum crossbars. The trailer comes with a 47,000-lb standard coil haul package and is designed to weigh less than some all-aluminum flatbeds. This flatbed is designed to be efficient and productive to offer long-term value and lower cost of ownership for users.
