Also can choose this type of lock. If the nobody is like a high value room like a warehouse. Choosing the above lock is obviously not enough. So you should choose high-strength materials with anti-prying process of the volume gate.

Noise
      The biggest drawback of the traditional roll gate is the noise. Open the door of the piercing, the wind of the dynamic ring. Rushing loudly. Disturbing dreams. So if you have a living room. You should choose a door with a silencer.
