ABSTRACT:
A grain bin floor panel formed from sheet metal. The grain bin floor panel is comprised of a first flange, a second flange, and a center support disposed between the first flange and the second flange. The center support is connected to the first flange by a first support surface and the second flange by a second support surface. To insure that the first and second support surfaces do not become separated from one another, the center support is configured with at least one staking. To provide the floor panel added strength, the first flange, the second flange, the center support, and the first and second support surfaces are preferably corrugated. To further increase the strength of the center support, the center support is preferably shaped as a triangle.
