What material is a good interior door lock?

1. Pay attention to lock materials.

When buying an indoor door lock, you must pay attention to the material of the lock. Earlier we said that stainless steel locks are the best, in addition to stainless steel locks, copper locks and zinc alloy locks are also a good choice, copper locks have superior mechanical properties, but the price is also relatively high; The zinc alloy lock is strong and wear-resistant, and has strong corrosion resistance.

2. Observe the treatment quality of the surface of the lock.

Observing the quality of the surface treatment of the lock is also the key to measuring a good lock. At present, there are three main types of surface treatment of locks on the market, namely coloring, painting and electroplating, which are all in order to add a dense protective film on the surface of the lock, in addition to the role of anti-corrosion and anti-rust, but also to make the lock more beautiful. These three treatment methods are undoubtedly the best electroplating, the plating is smooth and uniform, the color is bright, there are no bubbles, and the anti-corrosion and anti-rust ability is first-class.

3. Check the lock implementation standards.

The locks are implemented according to the standards, and some foreign locks are implemented according to the QB standard, and the quality of the locks is also higher, so the imported locks are generally more expensive. Now some brands of locks in China have been implementing the QB standard, and only some small manufacturers are still implementing the original GB standard, so you must see the implementation standard of the lock when you buy.

4. You can feel the quality of the lock.

In addition to observation, we can also feel the quality of the lock. Generally speaking, the heavier the lock, the thicker the material used on the surface, the more resistant to wear and tear, and the higher the quality will be. On the contrary, the lighter the lock, the weaker the material, the lower the quality, and easy to damage.

5. Check whether the lock cylinder spring of the lock is sensitive.

You can open the lock cylinder repeatedly to see the sensitivity of the lock cylinder spring, if it is not very sensitive, do not buy it.

Indoor door locks are made of more materials such as zinc alloy, stainless steel, and copper. This is my home Huangding interior door lock, zinc alloy.

Zinc alloy, Cabe is good.

Jixin all-copper lock cylinder lock is better, durable, good usability, it is not recommended to use stainless steel lock cylinder, the key will be worn out for a long time, resulting in not being able to pull out.

I feel better than stainless steel

It also depends on the appearance.

Pure copper is also good.
