Abstract: A trailer (100) is provided that transports coils (20) in a trough formed by at least one pair of longitudinally extending spaced-apart support members (8,8') that extend upwardly away from each other towards the bed plane (BP) of trailer (100) such that a peripheral portion of coils (20) are engaged by support members (8,8') below bed plane (BP). Trailer (100) preferably includes containment structures (10, 10') to provide a cage-like structure about support members (8,8') and coils (20) and further preferably includes protective covering over coils (20) in the form of clam shell like sections (16, 16') as well as bar members (32) on opposite sides of each coil (20) that are operative to prevent coils (20) from telescoping.
