1. Don't choose some three no-manufacturers and three no-products on the market in order to get rid of the cheap price of fire doors.
2. Do not arbitrarily lower the level of the fire door. When there is no fire or other accident, there is no difference in the function of the fire door and other doors. It is necessary to make a difference, that is, the fire door is more "heavy" and "higher" in quality and appearance. But don't forget that the original intention of our choice of fire doors is that when there is an accident, there is still room for recovery and a lifeline. In fact, it is equivalent to buying an insurance for yourself, so that you can be more assured and more secure.
