Security doors serve a primary function of preventing theft, with aesthetic appeal being a secondary consideration. When purchasing, it is crucial to focus on the anti-theft performance and overall quality. In terms of manufacturing, southern-made security doors often emphasize style and fashion, offering an attractive appearance, while northern-made doors tend to prioritize material thickness and durability, sometimes at the expense of aesthetics. Therefore, when buying, it's essential to balance both appearance and functionality. Opting for well-known brands is generally recommended, as they are more likely to meet industry standards. A genuine security door uses approved materials and technologies, and if the price seems unusually low, it may not meet the necessary anti-theft requirements. This is especially important in rural markets, where cheaper options might lead to higher long-term losses due to poor quality.
The design and structure of a qualified security door include several key elements:
1. **Door Size and Opening Direction**: Standard household doors come in four main sizes, represented by four digits indicating width and height. For example, a door opening of 1 meter wide and 2.1 meters high would be labeled as 1021. Common sizes include 0920, 0921, 1020, and 1021. The opening direction can be inward or outward, and each can be left or right-handed, depending on user preference.
2. **Surface Quality and Safety**: A high-quality security door meets national standards. The steel frame should be at least 2mm thick, while the front and back panels of the door leaf should be between 0.8mm and 1mm. Inside, there’s a reinforced skeleton and filling material like foam, asbestos, or honeycomb board to increase structural strength. The surface should be smooth, free of bubbles, and evenly painted. The door should weigh over 40kg, and rubber seals are commonly used to prevent harsh metal sounds during operation.
3. **Hardware Safety**: The lock is the most critical component. It should be certified by the relevant authority and offer features such as resistance to drilling, cutting, smashing, pulling, and technical entry. Locks can be either mechanical or electronic, with multi-point locks providing better security by locking at multiple points around the door frame. The bolt extension length should be at least 14mm for Class A and 20mm for Class B doors. The outer casing must be strong, with protective measures against drilling near the locking mechanism.
4. **Hinges**: Hinges connect the door to the frame and support the door body. They are typically built-in or external, with a shaft diameter of at least 12mm. The edges should be welded or stamped for added strength.
When purchasing a security door, consider the following factors:
- Ensure the manufacturer has a valid "Production License Registration Certificate" from the public security department.
- Verify that the product has a recent inspection report from an authoritative agency, matching the batch number and model on the actual door.
- Check for a product tag code, including the security level (A, B, or C), with C being the highest level of protection.
- Inspect the materials for thickness and finish, ensuring the steel plate is smooth and heavy.
- Evaluate the construction for even joints and fine craftsmanship.
- Test the lock for smooth operation and ensure the door opens and closes without sticking or making noise.
- Confirm that the gap between the door and frame is within acceptable limits (no more than 3mm on sides and top, 5mm at the bottom).
- Ensure the door includes an anti-theft chain that is securely installed and easy to use.
- Always request a detailed invoice and contract, including the name, size, quantity, price, and total amount.
- Keep contact information for the seller and manufacturer to address any potential issues promptly.
By paying attention to these details, you can make an informed decision and choose a reliable, secure, and aesthetically pleasing security door.
