A Frame is the orange structure generated when a Quarry is placed and powered.

When the Quarry is removed/destroyed the Frame will remain until removed by the player.

As long as the Quarry is powered it can regenerate, so any damage to the Frame will be almost immediately repaired (with no loss of function).

The only use for Frames, apart from in a Quarry, is as decoration or to be recycled into Scrap using a Recycler.
