Truck Trailer

What kind of truck or trailer needed to transport wood, steel and composite materials?

Im doing a report on the trucks construction, I need to know what type of trucks and trailers used for transporting lumber, steel and composites. Is it just a truck garbage or is a special trailer that is used to accommodate each different material? thanks a lot

My thoght first would be what is called a trailer of "flat bed". It's just a trailer with no sides or top. He dived through a point, or if small enough, can be pulled by a pick-up big as a F-150.
