System doors have excellent performance in terms of security and anti-theft.
Advantages of Materials
- System doors usually adopt materials such as thermal break aluminum alloy . This kind of material has high strength and is not easy to deform. The thermal break design not only enhances the stability of the door but also effectively prevents heat conduction. Moreover, aluminum alloy has strong corrosion resistance, can adapt to different climatic conditions, and can maintain good performance after long-term use.
- Some high-end system doors will also adopt a multi-layer composite structure. The outer metal material is hard and wear-resistant, and the inner layer can be filled with materials such as fireproof and soundproof ones. There may also be reinforcing bars in the middle layer. Such a structure makes the door as a whole very solid.
Lock System
- System doors are generally equipped with high-level anti-theft locks. For example, they adopt Class C lock cylinders, which have complex internal structures with various special-shaped pins and wafers combined. The shapes of the keys are also complex and diverse, with complex grooves on both sides or multiple sides, greatly increasing the difficulty of technical unlocking.
- Besides the lock cylinder, the bolt part of the door lock is also crucial. The bolts of some system doors adopt a multi-lock-point design, with bolts popping out at the top, bottom, left and right. When the door is closed, these bolts can be tightly inserted into the lock grooves of the door frame, making it very difficult for the door to be pried open by external forces.
Installation Process
- System doors have high requirements for installation precision. The connection between the door frame and the wall is tight and stable. It is firmly fixed on the wall by means of expansion screws and other methods. And during the installation process, materials such as sealant will be used to ensure that there is no gap between the door and the wall, leaving no space for criminals to pry the door.
- Accessories such as hinges of system doors are also very important. High-quality hinges can bear the weight of the door and can rotate flexibly. Meanwhile, they have strong anti-destructive ability to prevent the door from being easily removed.
