The country has strict requirements for the production of anti-theft doors, categorizing them into four levels (A, B, C, D) based on the resistance to destruction time. Level A must withstand at least 30 minutes, Level B at least 15 minutes, Level C at least 10 minutes, and Level D at least 6 minutes.
Security doors are available in two materials: steel and stainless steel. The steel thickness of the door frame must be at least 1.5mm, and the steel thickness of the door leaf must be at least 0.8mm. The weight of the door is generally over 40kg.
