Abstract: A fabricated steel ladder is provided particularly adapted for use on the sides of railroad cars and the like wherein the ladder rungs are formed with ends turned in 90 degrees in a manner so that cracks are avoided in the steel grains adjacent the inner radius of each turned end. A special indentation is formed on the inside surface of the turned end adjacent to the point of bending--the indentation causing a desired material flow so as to avoid cracking while increasing the material strength. The rung ends are cold headed during assembly with the other components of the ladder structure which avoids the necessity of separate fasteners used in prior art designs, and insures that substantially no radial clearance will be left between the rung ends and the apertures in which they are mounted and furthermore insures that the rung will be firmly affixed to the ladder stiles in an axial sense so as to eliminate looseness and rattle in the resulting structure.
