The difference between 9 cm and 7 cm of security doors is the difference in thickness.

The national standard door generally has four specifications, the height is 2050mm and 1970mm two heights, the width is 860mm and 960mm, the combination can be *960, the height of 2050mm is the total height of the door frame, if the user's door height is 2070mm, you can buy 2050mm height, you need to leave a margin of about 20mm, it is easier to adjust when installing.

In addition, 9 cm security doors are generally made of aluminum alloy, steel plate and other materials and closed, while 7 cm security doors are mostly made of steel plates, wood boards and other materials.

Therefore, the 9 cm security door can not only provide better security performance, but also better sound and heat insulation. However, it should be noted that the thickness of the security door is not the only consideration, but also the material, lock cylinder, structure and other factors of the door.
