Metal locks are made of a variety of materials in our daily life, and they have various processing technologies with different specifications. How to choose a lock for your door? The tips on purchasing a lock are as the following.
Checking materials of locks
The lock materials on the market are basically divided into stainless steel, copper and zinc alloys. Stainless steel has high strength and good corrosion resistance, and it does not change colors. Stainless steel is the best material for making locks. Copper is more common to manufacture locks, and it has superior mechanical properties and higher prices. Locks made of zinc alloys with good quality have good wear resistance and good corrosion resistance. Zinc alloys are easily manufactured and mostly used for mid-end locks.
Checking surface treatments of locks
There are three kinds of surface treatments for locks, which are electroplating, spraying and coloring. A layer of dense protective film is formed on the surface of the lock so as to protect the lock from corrosion and rust, making the lock more beautiful and durable. A layer of dense protective film is also a measure of the quality of the lock. Locks with good quality are processed by electroplating. The coating is delicate, smooth, uniform and bright in color and has no bubbles and signs of rust and oxidation.
Checking the standard of locks
Foreign countries have very strict standards for metal locks, so the quality of imported products is relatively good. You can use your hand to weigh the lock. In general, if the lock is heavy, its quality is relatively good. There should not be sharp corners for the lock body. The sharp corner easily hurt people. We should especially pay attention to the edge of the lock handle, the lock tongue and four corners of the lock body. Locks with good lock springs can be used flexibly and have longer service life. Locks also have a variety of styles, and they must be consistent with the style of the interior doors.
