How to buy a safe box
2024-05-28
  • A safe box is a specialized container designed for secure storage. Based on their functions, safes are primarily categorized into fire safes, anti-theft safe boxes, anti-magnetic safe box, fire and anti-magnetic safe box, and fire and anti-theft safe boxes. Each type of safe box adheres to its own national standards, with fire and anti-theft safes being the most common on the market.

  • Anti-theft safes can be further divided into mechanical and electronic types, based on the mechanism of the lock. Mechanical safes, known for their affordability and reliability, were prevalent in early designs. They typically feature mechanical locks. On the other hand, electronic safe box use electronic locks, such as digital keypads and IC cards, offering greater convenience, especially in settings like hotels where passwords need to be changed frequently.

    The history of safes dates back to the Middle Ages. Medieval paintings often depict wooden cabinets used to store valuables like gold and silver, serving as prototypes for modern safes. Today, safes come in various forms, including wall safes and floor safes.

  • How to buy a safe box

    1. The difference is from the external packaging of products. Generally, safe products produced by regular manufacturers will clearly mark the product name on the product packaging, rather than deliberately blurring the concept and confusing the product. Such as: T-type collection cabinet, boutique safekeeping cabinet, electronic code safe, mechanical safe, etc. From these names, we can correctly distinguish the safe from the treasure chest.

    2. Open the outer package and check whether the product itself is labeled with CE and VDE marks. If it is labeled with CE and VDE marks, it should be a real safe.

    3. Carefully check the appearance of the product, and check the appearance of the product, the connection degree of door seam, whether the box is polished smoothly, the opening of lock, safety performance, etc.

    4. Open the product and distinguish it from the thickness of steel plate, especially the thickness of door plate. The steel plate thickness of door plate of safe products with good quality is no less than 10mm, and it is composed of a whole steel plate. In contrast, the steel plate thickness of products with poor quality is very thin, and it may be combined by two steel plates.

    5. Carefully check the box to see how the steel plates on all sides are connected. The box of a good safe is formed by one-time stamping of steel plates. There are almost no gaps on all sides, which has a very good anti prying performance. At the same time, tap the box gently and listen to the sound. The box of a good safe is completely composed of all steel plates, which will have a very clear sound when knocked. Some products are composed of two very thin iron sheets inside and outside, filled with sand in the middle, which will make a very dull sound when knocked.

  • 6. Purchase of anti-theft safe

    Most of the anti-theft safes in the market are A1, with various shapes and styles. Consumers can buy them according to their needs. No matter what style of anti-theft safes they buy, consumers should pay attention to the following aspects:

    ① The color of the paint film (or plastic sprayed film) on the external surface of the anti-theft safe shall be uniform, and there shall be no obvious cracks, gas robes, spots and other defects.

    ② For anti-theft safe with cabinet height ≤ 600mm, the upper, right and left clearance between cabinet door and door frame ≤ 1.5mm, and the lower clearance ≤ 2mm. If the gap is too large, the anti-theft performance will be reduced.

    ③ When the mass of class A and class B anti-theft safes is less than 340kg, there shall be installation and fixing holes, fixing parts and instructions for fixing, which shall be fixed in time according to the requirements of the instructions.

    ④ Generally, the thickness of the door plate of the anti-theft safe is 8mm ~ 10mm, and the thickness of the cabinet body is more than 6mm, so as to ensure the anti-theft performance. When purchasing, you should ask the store about the thickness of the steel plate.


  • Frequently Asked Questions
