The country has strict requirements for the production of anti-theft doors, categorizing them into four safety levels based on the resistance to destruction time: Class A, B, C, and D. Class A must withstand for at least 30 minutes, Class B for at least 15 minutes, Class C for at least 10 minutes, and Class D for 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 door leaf steel thickness must be at least 0.8mm. The weight of the door is generally over 40kg.
