Good door locks are really expensive. Is it necessary? What should be done to choose the door lock?

Expert guidance: If you choose the door lock, then its anti-theft performance requirements are relatively high. At present, good door anti-theft locks use steel as the main material, and steel has higher hardness and firmness than cast iron.

The indoor door locks are mainly private, with decorative features, reflecting a home quality. Since there are many times of opening, it is necessary to have good quality. The first is wear resistance, which is related to the wear resistance of the material of the door lock. When purchasing, ask the dealer what kind of material is made. Because of the frequent use, the feel of the door lock is also very important. The feel of the door lock is determined by the spring. The quality of the spring determines the feel and service life when used. Some lock springs are not good, so it is easy to cause the handle to sag, thereby ending the life of the door lock. When you buy, you should try the toughness of the door lock spring. The feel of a good spring is very soft, not too soft or too hard. In the purchase process, you should also look at the plating of the door lock, that is, whether the handle of the door lock will fade. In general, the protective layer of a good door lock, that is, the coating will not be easily oxidized and worn. The plating of the door lock handle is related to the overall aesthetic of the living room, so this cannot be ignored.
