You don't need to change the whole set of locks, you can change the lock cylinder, about 100 yuan, and you need to add 30-50 yuan for door-to-door installation.
Security doors range from more than 1,000 to more than 6,000, depending on your own needs and what kind of brand and style you like.
Large equipment: 1 shearing machine, 1 bending machine, 4-5 punching machines, 2 electric welding machines, 1 cold pressing machine, 1 oven, spray table, pickling phosphating tank.
1500 out of 1000 for grade D, about 2500 for grade A, which is the price of a single door of the national standard.
It is 3 0-50 yuan, if you ask someone to replace it, it may cost about 150 yuan, you can go to the door lock website to see if you are sure.
