Do developers need to change security doors when handing over houses?

In my opinion, there is no need to change it. This depends on whether the developer has a conscience. If people in a community basically don't change their security doors, the quality will be better. However, if you say that there are valuable things at home, and then you are not at ease, then you can consider changing it to your choice. However, the security door configured by the developer is for its own benefit, but it will also take into account the safety of the community.

Now the common security doors on the market are all made of steel, and other security doors also occupy a certain market. Common security door materials are: steel, stainless steel, copper, steel-wood structure, aluminum alloy. Advantages of steel doors: the most common, high market share, low and reasonable price. Disadvantages: the external lines are hard, so it is difficult to integrate with modern interior decoration.

In China, the level of security doors is divided into four levels: A, B, C and D. The quality of A-level security doors is the best, followed by B, C and D. This division is determined according to the filler of security doors and the length of anti-theft time. Whether to change it or not depends on the quality of the security door equipped by the developer. If the developer uses an A-class door, there is no need to change it.

Sometimes the doors provided by developers are not security doors, but "engineering doors". These doors are generally not strong, and the lock core is likely to be Grade A or Grade B. Thieves can easily pry it open, which is not safe at all, and it is likely to cause great losses to family property.

Then when we buy security doors, we should be careful not to choose too thin door bodies. The security door that is too thin has poor performance and the lock core is not very good. Fingerprint locks are very popular in the market now, compared with their safety and practical performance. Even if you forget your keys at ordinary times, you won't be embarrassed when you enter the house.
