Iron entrance doors with security features blend architectural beauty with robust anti-intrusion technology. The door panel is constructed from high-strength steel (5–6mm thick), with multi-layer cores (anti-dent outer layer, honeycomb energy absorber, reinforcing grid) that resist forced entry—testing shows no penetration after 45 minutes of attack with tools like crowbars. Locking systems are high-security, featuring multi-point deadbolts (top, bottom, sides) engaging into steel strike plates embedded in the frame, operated by anti-drill, anti-pick cylinders. Hinges are tamper-proof, with non-removable pins and anti-pry plates, constructed from hardened steel (55HRC) to withstand cutting. Additional security options include ballistic steel inserts (NIJ IIIA rating), explosion relief vents, and vibration sensors that trigger alarms when tampered with. Smart security features like biometric readers (fingerprint, iris scan), encrypted RFID locks, and smartphone-controlled access systems can be integrated. These doors undergo rigorous security testing (EN 1627 Class 4), making them suitable for high-risk residential areas, commercial properties, or institutional buildings.
