      The advantages of anti-theft door components are mainly reflected in safety, durability, functionality, and adaptability. Different components achieve a balance between anti-theft effect and user experience through collaborative design. Starting from the core components, analyze their technical characteristics and application advantages as follows:
1、 Door frame and leaf: the fundamental guarantee of structural safety
1. Door frame: Stable installation and anti pry core
      Material advantages: Cold rolled steel plates or galvanized steel plates with a thickness of 2mm or more are commonly used, with high strength (tensile strength ≥ 345MPa), strong impact resistance, and the ability to resist external impact or pry bar prying.
Installation design:
      The door frame and wall are fixed with expansion bolts (usually ≥ 4 fixing points) to prevent overall disassembly;
      Some products have "anti pry grooves" on the inside of the door frame, and when the door leaf is closed, the locking tongue/locking point is embedded in the groove, forming a "bite structure", which increases the difficulty of prying the door.
      Sealing and Sound Insulation: EPDM rubber sealing strips are installed at the edge of the door frame to enhance sound insulation while preventing water and dust (with a sound insulation level of over 30dB), balancing safety and comfort.
2. Door leaf: multi-layer protection and resistance to damage
Composite structure design:
      Outer layer: 1.0-1.2mm thick steel plate, surface treated with phosphating and spray coating, rust resistant (no rust after salt spray test for ≥ 48 hours), and wear-resistant (not easily scratched by keys);
      Middle layer: filled with fire-resistant rock wool, honeycomb paper or polyurethane foam to enhance insulation and sound insulation performance, while also strengthening the door leaf's resistance to deformation (such as not easily sinking under external impact);
      Inner layer: steel plate+decorative panel (such as wood grain transfer printing, PVC film coating), beautiful and easy to clean.
      Thickness advantage: The standard anti-theft door leaf thickness is ≥ 60mm, and the product can reach 90mm. The internal skeleton (such as square tube keel) enhances rigidity to prevent violent kicking of the door and deformation of the door leaf.
2、 Lock system: the core component of anti-theft technology
1. Mechanical lock body: prevents technical opening and violent damage
      Number of locking points: The standard anti-theft door lock body should have at least 6 locking points (upper and lower hooks+side locking points). When closing the door, the locking points should be evenly distributed around the door leaf to prevent a single point from being breached.
      Lock tongue material: Made of 304 stainless steel or copper, with high hardness (Rockwell hardness ≥ 50HRC), resistant to sawing and drilling; Part of the lock tongue is designed as a combination of "slanted tongue+square tongue", with slanted tongue facilitating automatic locking of the door, and square tongue preventing violent impact on the door.
Lock cylinder level:
      A-level lock cylinder: simple structure (such as a single/cross key), anti lock technology opening time ≤ 1 minute, only suitable for low security demand scenarios;
      B-class lock core: adopting blade and edge column structure, with anti technology opening time ≥ 5 minutes, mainstream in the market;
      C-level lock core (super B-level): mostly consisting of double row blades and serpentine slots, with an anti lock technology opening time of ≥ 270 minutes, and a complex key slot (such as mother and child beads, curved wire slots), it is currently the most anti-theft mechanical lock core.
2. Intelligent locks: Upgraded convenience and security
      Biometric recognition technology: fingerprint recognition (live capacitive, false rejection rate ≤ 0.1%, false recognition rate ≤ 0.001%), facial recognition (3D structured light, anti photo/video forgery), to avoid the risk of key loss or duplication.
Electronic protection function:
      Anti peephole activation: Built in "anti peephole paddle" to prevent tools from being inserted into the lock through the peephole;
      Abnormal alarm: trial and error alarm (automatic locking after continuous input of incorrect password/fingerprint ≥ 5 times), violent activation alarm (vibration sensor triggers buzzing alarm);
      Remote monitoring: Some smart locks support Wi Fi connection, and the mobile app can view real-time door opening records and remotely authorize temporary passwords (such as temporary use by visitors).
3、 Hardware Accessories: The Key to Durability and User Experience
1. hinges: load-bearing and anti destructive design
      Material and Structure: Made of 304 stainless steel or cast steel hinges, with a single load-bearing capacity of ≥ 80kg (standard door weight is about 40-60kg), to prevent the door leaf from sagging; Some products are "hidden hinges" with no exposed screws on the outside to avoid being disassembled by pry bars.
      Rust prevention treatment: The surface is treated with electroplated nickel chromium or Dacromet, and there is no rust after salt spray testing for ≥ 1000 hours. It is suitable for humid environments (such as bathrooms and outdoor doors).
2. Cat Eye and Anti Cat Eye Devices
      Cat's Eye: Using an optical glass lens with a viewing angle of ≥ 120 °, it can clearly observe the situation outside the door. The inner diameter of the lens is ≤ 16mm to prevent tools from entering and prying the lock;
      Anti peephole device: Equipped with a knob or baffle inside, the peephole can be closed at night to prevent outsiders from peering into the room through the anti peephole tool.
3. Lower gear (threshold): Waterproof and anti pry design
      Using steel plates with a thickness of 1.5mm or more, with a water stop edge at the bottom to prevent rainwater from flowing back; Part of the product thresholds are welded together with the door frames to enhance overall integrity and avoid violent damage.
4、 Additional functional components: scene adaptation and humanized design
1. Integrated fire and anti-theft components
      Some anti-theft doors have passed fire certification (such as GB12955-2008 fire protection standard), and the door leaf is filled with fireproof rock wool (fire resistance limit ≥ 1.5 hours), which has both anti-theft and fireproof functions and is suitable for high-rise residential and commercial buildings.
2. Soundproofing and insulation optimization components
      Multiple sealing strips are added to the gap between the door frame and the door leaf, and filled with honeycomb paper or polyurethane. The sound insulation level reaches 35dB or more (equivalent to a library environment), and the insulation performance reaches K value ≤ 3.0W/(㎡· K), suitable for street facing residential areas or scenes with high sound insulation requirements.
3. Anti pry alarm device
      The door frame or lock body is equipped with a micro switch, which triggers an audible and visual alarm (volume ≥ 80dB) when forcefully pried, and pushes the alarm to the mobile app to scare away intruders.
