Although door of security against theft is steel qualitative door, steel hardness achieves national standard, but when opening close door still should push as far as possible pull gently. A long time of violent impact will make the security door parts loose, reduce the service life oh.

It is suggested that close people do not tear the protective film on the door fan before finishing decoration, because metal tools cause scratches easily to the door fan, or cause irreparable damage.  

3. Hardware maintenance  

After installation and use for a certain period of time, metal friction may be emitted. This does not mean that the product has a quality problem, or there is a component damage, most likely due to the lack of lubrication of the hinge, lock tongue. Regular in the door hinge, lock oblique tongue and other mechanical rotating parts to add a little lubrication grease, keep the door and lock flexible opening and closing, but also can make the parts used for a longer time.
