Anti-theft doors, also known as security doors, are designed to provide both safety and protection, making them a popular choice in modern construction. These doors come in different security levels and are made from various materials, which can make it challenging for consumers to choose the best option. If you're a layperson looking to buy a high-quality security door, here are some key points to consider.
First, pay attention to the security level of the door. Security doors are typically classified into three levels: A, B, and C, with C being the highest level of security, followed by B and then A. Most security doors found in retail stores are Class A, which is suitable for general residential use. However, if you're looking for maximum security, consider upgrading to a B or C-rated door.
Next, check the quality of the door frame. The steel plate thickness should be at least 2mm, and the door itself should be at least 20mm thick, weighing over 40kg. When you remove the peephole, doorbell box, or handle, you should be able to see that the door panel has a steel thickness of at least 1.0mm. Inside, there should be reinforcing bars connecting the front and back panels. Some high-quality doors use fireproof, heat-insulating, and soundproof materials like asbestos as fillers. Tapping the door should produce a solid "thud" sound, not a hollow one.
The lock is another crucial component that determines the door's security. Make sure the lock is certified by the relevant authorities, such as the public security department. The lock area should be reinforced with steel plates that are at least 3.0mm thick to prevent forced entry.
Finally, don't forget to check the after-sales service provided by the manufacturer. After installation, ensure that all necessary items—such as keys, warranty documents, invoices, and service guarantees—are included and match what was promised. This helps protect your investment and ensures long-term satisfaction.
