電梯門套與普通門套的區別

The difference between elevator door frames and ordinary door frames

1、電梯門套是由兩個部分門套構成的：

1. The elevator door frame is composed of two parts:

一部分是電梯構造自身的鋼門套，也是我俗稱的“小門套”。

Part of it is the steel door frame of the elevator structure itself, also known as the "small door frame".

一部分是由裝飾材料做的裝飾門套，也就是我們大多數設計師認為的電梯門套。

Part of it is a decorative door frame made of decorative materials, which is what most designers consider to be an elevator door frame.
