How it's used
Refers specifically to the heavy, retractable metal security gate found outside almost every apartment in Hong Kong. It is distinct from the main wooden door, which is usually referred to as 木門. People often use the classifier 道 when referring to these gates, emphasizing their role as a barrier.

Common mistake
Learners often forget that in Hong Kong, most homes have two doors: the inner wooden door and the outer metal gate. If you just say 門, people might be confused about which one you are referring to, so specifying 鐵門 is necessary for clarity.
