Norman was pulling her down on to the hard metal floor.

There were more hits; he could feel each one shake the metal floor.

And only his feet made any sound on the metal floor.

The sound of one foot tapping on the metal floor.

There's no seat back there, just a cold metal floor.

The hard metal floor felt cold to Grant's bare feet.

And now he had passed through the metal floor of the cage.

The opening was wide enough to show a fragment of a metal floor.

Then- slowly- he eased himself down on the metal floor.

The metal floor rang with the sound of heavy footsteps.
