[Galaxy Quest] Why were there giant, crushy metal things in the hallway in the original show?

Why did the Protector ship have random crushy metal things in the hallway?

The real reason is that they realized that the episode wasn't exciting enough if the crew could just safely walk there, so the writer added some drama by having the giant crushy metal things. Back then, it was more about getting an episode finished on time than it was about having it make sense to a legion of fans with too much time on their hands. 

Um. You know. (looks around sheepishly)

The current leading theories proposed at Galaxy Quest fan conventions are that they're a venting system for the plasma chambers connected to the ship's engines, or gravity stabilizers that need to highly regulate the ship's artificial gravity, or a malfunctioning security protocol.
