Abstract
A rail car sliding door includes a substantially rectangular frame having a pair of side frame members and top and bottom frame members which are secured to each other. At least one corrugated panel is secured to the frame. Top, bottom and side reinforcing channels are secured to a respective one of the frame members for door strengthening purposes. The top and bottom reinforcing channels extend over the side reinforcing channels to the door side edges for better bearing loads imposed on the door. The door may advantageously be provided with a corrugated metal panel in which substantially equal amounts of panel material are provided on each side of a plane which bisects the door thickness dimension. The door also may advantageously be provided with a hasp which is secured to the door by means of a U-shaped hasp securing member.
