What are the functions of a burglar-proof door? As the name implies, they serve the purpose of preventing burglary and can protect our homes. When choosing a burglar-proof door, one must pay attention to the quality of the product, as there are many brands and varying prices on the market. With so many types of burglar-proof doors, how are they categorized?

Now, there are many types of security doors on the market, which can be categorized into three types: grille security doors, solid doors, and composite doors.

2. The grille-style security door, commonly seen in daily life, is typically made of welded steel pipes. Its advantages include good ventilation, light weight, and aesthetically pleasing design, with a relatively low price. The upper part consists of grille-style steel pipes or steel disks, while the lower part is made of cold-rolled steel plates. It employs multi-locking points for enhanced security against forced entry. However, it is not as effective as a fully enclosed security door in terms of burglary prevention.

3. The solid doors are made by extrusion of cold-rolled steel plates, with all panels being steel. The thickness of the steel plates is mostly 1.2mm and 1.5mm, offering strong impact resistance. The door leaves are filled with rock wool thermal insulation and fire-resistant materials between double steel plates, providing functions such as theft prevention, fire resistance, thermal insulation, and sound insulation. Generally, solid security doors are equipped with features like peepholes and doorbells.

The composite security door is a combination of a solid door and a grille-style security door, featuring anti-theft capabilities, as well as protection against mosquitoes and flies in summer, ventilation for cooling, and sound insulation for warmth in winter.

5. Categorized by structural features, there are mainly sliding grille security doors, swing grille security doors, plastic bas-relief security doors, and multi-functional luxurious security doors. For general consumers, residential security doors primarily refer to swing grille security doors. Swing doors are currently the most in-demand type of security door in the market. Some standards refer to this type of door as a household door or entrance door, indicating it serves as a dividing line between indoor and outdoor spaces. Therefore, in addition to security, they also involve aspects such as thermal insulation, soundproofing, and aesthetics.
