How much area of the office can be opened with single fire rate doors, and how much area should be opened with double fire exit doors? I believe many people are not clear. The following Golden House Door Factory will introduce to you, how big is the office with double doors?
1: The setting of double doors has little to do with the office area, but has to do with the size of the door opening;
2: Generally 1m and below are single-opening, 1.2m is semi-fixed and semi-opening, 1.5m and above are double-opening, of course the width is greater than 1.2m, and double-opening doors can also be used.
