It's a steel door (w/ foam core probably). The threshold is aluminum but I hadn't checked to see if the strip that runs under the door is adjustable. There are visible screws holding it down but that's as far as I got.
Just finished up sealing the tile last night so I'll focus on the door this weekend, and hopefully get some pics up so you can see what I'm talking about.
The weatherstripping on the door looked like this (although the threshhold in the pic is not):
