Established in 1999, FUYU door lock has gradually become one of the most famous door lock manufacturers in China because of high quality, high added value, variety and variation.


To be shipped, Fuyu Hardware employees are carefully checking every door lock.


  The door locks are produced and tested from a series of processes such as lock core, lock body, die casting, assembly, and so on. After every lock is made, the production staff should check all the locks they have done, then use the digital spring tension tester (endurance tester), lock durability tester, salt spray testing machine. A series of testing procedures, such as lock tongue closure life test, torsion spring durability test, image measuring instrument (digital size detector), etc.

   We clean the surface again, check it completely, pack it again, count the quantity before shipping. The procedure is complex, but Fuyu Hardware employees take each procedure seriously, in order to produce high-quality products.
