Abstract: This disclosure relates to a system and method for insulating a mill product during a transporting and storing process. The system includes a platform, an insulated enclosure, and an actuator system. The platform is capable of supporting the insulated enclosure and the mill product. The insulated enclosure includes a first clamshell enclosure member and a second clamshell enclosure member supported on the platform. Each enclosure member has an open position and a closed position. When each enclosure member is in the open position, the mill product supported on the platform within the enclosure may be accessed. When each enclosure member is in the closed position, the mill product is thermally insulated within the enclosure. The actuator system can move the clamshell enclosures between their open and closed positions.
