- a roof frame having a plurality of girders and deck sheeting disposed over the plurality of girders, the plurality of girders including a first pair of generally parallel, spaced-apart girders and a second pair of generally parallel, spaced-apart girders extending between and forming generally right angles with the first pair of girders, the deck sheeting having an opening therein between the first pair of girders and between the second pair of girders;
- a plurality of support angles mounted on the deck sheeting above the first pair of girders and the second pair of girders and forming a well in the roof frame; and
- an assembly mounted within the well.
- 2. A floating roof in accordance with claim 1, wherein the assembly comprises a manway assembly having a removable cover.
- 3. A floating roof in accordance with claim 2, wherein the removable cover has a flange at an outer periphery thereof extending over the plurality of support angles when the cover is disposed over the well.

- 6. A floating roof in accordance with claim 5, wherein each of the first pair of girders has a side surface with a grooved slot therein, and the pair of opposite flanges of the bleeder guide assembly are coupled to the first pair of girders by threaded fasteners secured within the grooved slots in the side surfaces of the first pair of girders.
- 7. A floating roof in accordance with claim 1, wherein each of the first pair of girders has a side surface with a grooved slot therein extending along at least a substantial portion of the length of the girder, and each of the second pair of girders has a side surface with a grooved slot therein and is coupled to each of the first pair of girders by an opposite pair of mounting angles and a plurality of threaded fasteners extending through the mounting angles and into the grooved slot in the side surface of the associated one of the second pair of girders and into the grooved slot in the side surface of each of the first pair of girders.
- 8. A floating roof in accordance with claim 1, wherein each of the first pair of girders and each of the second pair of girders has a top surface with a grooved slot therein, and the plurality of well support angles are mounted by threaded fasteners extending through the well support angle and the deck sheeting and into the grooved slot in the top surface of one of the girders of the first pair of girders and the second pair of girders.
