What are the components of a burglar-proof door?
A security door consists of a lock, door frame, and door leaf. Security doors are primarily categorized into five types based on their material: steel, steel-wood composite, stainless steel, aluminum alloy, and copper. Each material has its own unique characteristics and performance, resulting in varying prices. Security doors are also classified based on their structural characteristics, with common types including sliding security doors, hinged security doors, plastic relief security doors, and multi-functional luxury security doors. For most consumers, the most common type of security door is the hinged security door. Hinged security doors are currently the most in-demand type of security door on the market. Some standards refer to this type of door as a partition door or entrance door, indicating that it is a door that separates indoor and outdoor spaces.
Different anti-theft door structures and characteristics
1、Perimeter-style anti-theft doors are the most common type, typically made of welded steel pipes. Their main advantages are ventilation, lightweight, aesthetically pleasing design, and relatively low cost. These doors consist of a perimeter-style steel pipe or steel plate upper section and a cold-rolled steel plate lower section, with multiple locking points to ensure anti-theft capabilities. However, they are less effective than solid-core anti-theft doors in terms of anti-theft performance.
2. Solid doors are manufactured using cold-rolled steel, with steel plates of typically 1.2mm and 1.5mm thickness, offering high impact resistance. The door leaf consists of two layers of steel plates filled with rock wool insulation and fire-resistant material, providing anti-theft, fire protection, thermal insulation, and soundproofing properties. Solid-core security doors typically include features such as peepholes and doorbells.
3. Composite anti-theft doors consist of a solid door and a mesh-style anti-theft door, offering features such as anti-theft protection, summer mosquito and fly prevention, ventilation and cooling, and winter warmth and sound insulation.
