A supported floor for use in a grain storage and/or drying bin is disclosed that is constructed of interlocking perforated flooring or panels of two designs each with a plank portion and subjacent flanges which alternate with each other. The first panel design has flanges which are outwardly turned to form a hat-shaped transverse cross section. The second panel design has channels which are inwardly turned resulting in a C-shaped transverse cross section. To assemble the supported floor, the hat-shaped panels are rested on supports which are arranged on the base of the bin in a predetermined manner. These supported hat-shaped panels are positioned in spaced relation to one another so that a C-shaped panel can be fit between each adjacent pair of the hat-shaped panels. Thereafter, the C-shaped panels are positioned in the respective spaces and interlocked with the hat-shaped panels. To gain access to the bin floor, any of the C-shaped floor panels can be lifted without affecting the hat-shaped panels.
