Details of Door Lock

·Observe the surface treatment of the lock

The surface treatment of door locks is broadly divided into three types: electroplating, spraying and colouring. It is understood that each lock will form a dense protective film on the surface of the product through surface treatment, which plays the role of corrosion and rust prevention, making the lock more beautiful and durable, thus ensuring the service life of the lock. If the door lock does not undergo a sound surface treatment, it is easy to rust when it is in use.


·Check that the product packaging is fully marked

The production information of the product includes the execution standard of the product, the grade, the name and address of the manufacturer and the date of production. It is understood that certain small-scale enterprises may cut corners in the selection of materials in order to reduce costs. Therefore, we recommend that you must choose a manufacturer that is large and well-known.
