Abstract: In a grain bin floor panel having first and second floor surface extending outwardly from a central support leg to respective first and second side support legs, the central support leg includes first and second upright portions and a lower portion connected between respective lower ends of the first and second upright portion. The first and second upright portions are connected to respective ones of the first and second floor surfaces at the upper ends of the upright portions and are spaced apart from one another at respective lower ends. The lower portion is generally concave such that the lower ends of the first and second upright portions together with the lower portion forms a concave quadrilateral.

Abstract: Floor support members in a grain bin floor system support perforated floor panels spanning above a plenum space at the bottom of a grain bin. Each floor support member includes a top rail including a horizontal top flange at a top end of the floor support member and a bottom rail including a horizontal bottom flange at a bottom end of the floor support. Each floor support member further includes a plurality of columns connected between the top rail and the bottom rail such that a top end of each column is abutted with the top flange of the top rail and such that a bottom end of each column is abutted with the bottom flange of the bottom rail. Clinching is used to fasten each column to the top and bottom rails.
