tonneau covers, since they usually lock and are made from a harder composition, but they take more time to install and are designed for semi-permanent installation. Fiberglass, hard plastic, or aluminium tonneau covers are also common. Some may be painted to match the truck, are solid in construction, and can be locked. These covers are usually heavy and require gas struts to assist in opening and closing. They operate much like a vehicle's hood, typically opening from the tailgate end of the bed (back to front). Some have multiple compartments that open front to back, back to front, side to side, or even rise vertically. Fiberglass, hard plastic, or aluminium tonneau covers are sometimes installed as a factory option on new vehicles.

Another style of truck bed tonneau cover is a retractable unit, which is mounted at the front and sides of the bed and rolls up or retracts from the tailgate towards the cab. The retractable tonneau is typically made of vinyl, plastic or aluminium. Retractable tonneaus are more secure than soft
