How to choose a lock?

1. Pay attention to the material of the lock

    The lock materials on the market are basically divided into stainless steel, copper, zinc alloy and so on. Stainless steel has high strength, strong corrosion resistance, and does not change color. It is the best lock material; copper is more versatile, has superior mechanical properties and higher prices; high-quality zinc alloy locks are strong and wear-resistant, have strong corrosion resistance, and are easy to form. Mostly used for mid-range locks. When choosing, if you consider the cost performance of ordinary life locks, it is recommended to consider zinc alloy locks.

    2. Pay attention to the surface treatment of the lock

    The surface treatment of locks can be roughly divided into electroplating, spraying and coloring. The locks form a dense protective film on the surface of the product through surface treatment, which plays a role of corrosion and rust prevention, making the locks more beautiful and durable. Dense protective film is also a measure of the quality of locks. Good quality locks are mostly electroplated. The coating is fine and smooth, uniform and moderate, with bright color, and no bubbles, rust and signs of oxidation. The surface treatment of the lock is not only for aesthetics, but also related to the service life and quality of the lock. Therefore, the surface treatment of a good lock must be passed.

    3. Pay attention to the implementation standards of locks

    Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. For domestic hardware locks, we must pay attention to its certification and implementation standards when purchasing. Under certain circumstances, choosing a relatively well-known big brand lock is relatively safe in terms of quality. In addition to these, we can also feel the quality of the lock by hand. Generally speaking, the quality of heavy locks is relatively better; the lock body should not expose the tip, which is easy to hurt people. Pay special attention to the three positions of the lock handle end, the lock tongue and the four corners of the lock body; the lock spring is good The locks are flexible to open, have high sensitivity, and have a long service life.

    In addition, when choosing hardware locks, especially indoor door locks, in addition to considering the quality of the locks, the style of the locks is also relatively important. It is best to choose a door lock that is consistent with the style of the indoor door.
