The thickness of the door frame steel plate should not be less than 2cm. The thickness of the door leaf should not be less than 2cm. The thickness of the front and rear steel plates should be between 0.8-1cm, and there should be a frame and reinforced version inside the door leaf, so that such a door is safe and complete.

You need to check the workmanship of the entire door, such as welding points. A good door should have good workmanship and no rough spots. There should be rubber seals embedded in the door frame so that there is no harsh metal clanking sound when the door is closed.
