A bin ladder construction includes a vertical ladder up the side of a grain storage bin and an inclined ladder from the upper end of the vertical ladder to the peak of the roof of the grain storage bin. Corner pieces of particular shape and configuration interconnect the inclined and vertical ladders. The ladders have hollow rungs open at both ends, and channel members extend through and beyond the ends of a pair of hollow rungs in the vertical ladder and in the inclined ladder. Triangular brackets mount the opposite ends of hand rails to the ends of said channels.
