ABSTRACT:
A door for railroad boxcars has a balsa core sandwich construction in which a balsa core is sandwiched between thin fiberglass skins and reinforced at the perimeter by steel tubes to provide an economical and lightweight door that exhibits the requisite structural strength. The door has a concavo-convex configuration that prevents thermally induced warpage from deforming the door in a manner to cause significant interference in its opening and closing movement.
