Such an important hardware lock learns that these three hardware locks are not a problem.
The importance of hardware locks for a home is self-evident, because it is related to the safety of your life and property, so you must be careful when choosing a hardware lock, in order to ensure the safety of the entire home. Below, I will teach you how to choose from three aspects, choose high-performance hardware locks. 
First, look at the lock implementation standards
Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. We can feel the quality of the locks. Generally speaking, the heavy lock has a relatively high quality; the lock body can not be pointed, and the tip is easy to injure, especially the lock handle end, the lock tongue and the lock body are three positions; the lock spring is good. Flexible opening, high sensitivity and long service life. There are also a variety of styles of locks, so be sure to keep in line with the interior door decoration style.
Second, look at the lock material
The lock material on the market is basically divided into stainless steel, copper and zinc alloy. High-strength stainless steel, strong corrosion resistance, no discoloration, is the best lock material; copper is more versatile, mechanical properties are superior, and the price is higher; the lock high-quality zinc alloy is strong and wear-resistant, corrosion-resistant, and easy to form. Mostly used for mid-range locks.
Third, look at the surface treatment of the lock
The surface treatment is roughly divided into electroplating, spraying and coloring. The locks form a dense protective film on the surface of the product through surface treatment, which acts as anti-corrosion and anti-rust, making the lock more beautiful and durable. The dense protective film is also a standard for measuring the quality of locks. The locks of good quality are mostly plated, the coating is fine and smooth, even and moderate, the color is bright, and there are no signs of bubbles, rust and oxidation.
Of course, in addition to these more common, we have to consider some other points:
1. The place used and its importance;
2. The environment, conditions and requirements for use, mainly to open the door left and right, to open the door inside and outside should pay special attention to not to buy the wrong;
3. Coordination with the decorative environment;
4. If there are elderly people, children or disabled people in the family, try to use them as convenient as possible;
5. Lastly, according to your own economic strength, some locks have very strong safety performance, but they are expensive and not suitable for ordinary working-class people.
