ABSTRACT:
In a floating cover for inside a tank a plurality of spaced parallel support bars extend across the tops of laterally spaced horizontal pontoons that support them. Metal sheets covering the spaces between the bars have edge portions resting on the bars and clamped against them by clamping bars to form a deck. The deck may be provided with vertical sleeves, in which posts of different lengths can be mounted for spacing the deck different distances from the bottom of a tank.
