About the vault door manufacturers, Xiao Bian has mentioned it many times in previous articles, but today I still want to talk to you about the issue of vault door manufacturers. Because Xiao Bian met a strange customer yesterday, he bought our set of vault door but it was troublesome for us to tear down the previous one. What has actually happened?
In fact, the manufacturer is not responsible for causing trouble. The customer had previously purchased a set of vault doors, but the use of results was unsatisfactory. From the beginning of the installation, it was not very smooth. I thought it would do as long as security can be achieved. I didn't expect it to be less than a year old.
The customer contacted the manufacturer several times and started to be controlled by people. It was simply impossible to find people behind. Angrily decided to change the door again, remove the original. This irresponsible factory gave us an opportunity, but this incident also tells a lot of friends who want to purchase the vault door. The manufacturer is really important!
If you do not talk about the problem of late maintenance of the manufacturer, it is just the quality of the previous product, and there will be differences. When we went to remove the door, we found that the door was poorly installed, and the size was not right. It was a bit of a forced installation. This is why the door started to cause problems in such a short time.
Small plants, whether they are molds or technologies, are not very stable, and they are prone to dimensional deviations and problems with installation. And for products such as the vault door, which have a relatively long life cycle, it is also very important for the manufacturer to maintain it at a later stage. The vault door manufacturers should be responsible for each and every one of the doors that are sold out. This kind of half-way running factory is really not reliable.
The purchase of the vault door has always been a matter of planning, safety, and confidence. If you choose to go to a bad manufacturer, it will only be bad, heart-warming, and annoying. Choose the regular large manufacturers, the quality of the vault door is guaranteed, the service is guaranteed, so that we can really enjoy the good life brought by the vault door.
