How do you see the quality of the security door? Is the quality of Dedun good?

First of all, don't choose the three-no brand, because3. No productThere is no guarantee of quality, and the after-sales service is not guaranteed, there are quality problems after buying back, I don't know who to repair, there will be a lot of trouble in the later stage; Secondly, choose the size that suits your door, you choose a brand product, and the manufacturer will arrange a special person to measure the size; Finally, look at the appearance of the security door, check the appearance and the quality of the lock cylinder.

Security door. The full name of the "anti-theft security door". It combines anti-theft and security performance. In accordance with the "General Technical Conditions for Anti-theft Security Doors".

It is stipulated that qualified security doors use chisels and screwdrivers within 15 minutes.

Ordinary hand tools such as crowbars and portable power tools such as hand drills cannot pry open or make an opening of 615 square centimeters in the door leaf or 150 square millimeters in the locking point.

Yesterday only installed the German shield anti-theft door, the door quality is super good, super quiet, especially the lock is very simple, the German patented technology is introduced, eliminating the cumbersome process of the traditional key lock door.

The brand of Deodun is OK, and the security door of my house is this brand.

1. Dedun is a big brand: there are many materials for anti-theft doors, metal materials, solid wood materials, and the sound insulation effect of anti-theft doors is very good.

2. The after-sales service of Dedun is very good, and the first year after the installation is free of charge, such as the door paint or other problems, you can find after-sales workers to deal with it for you, which is still good.

The workmanship of the door is not good, what German technology, I think it is still good in Chinese technology.

The quality of the Dedun is still OK, I have used the Dwandn at home for 2 years, and there is no problem at all. And compared with some doors on the market, Dedun's doors are much better, and the materials used in it are very real, better than the paper honeycomb used by other brands. And it is very soundproof, when my house is renovated, the door is closed, and there is no sound outside.

The quality of the security door is still very good, if it is suitable, you can buy it with confidence. Cost performance is still to look at the best and compare the quality to get the best choice, in other words, it can't be cheap.

However, it really doesn't mean that it's ***, and it may be pitted, so it is recommended to see more comparisons. Now as long as the anti-theft door is a regular product that meets the national standards, there is basically no need to worry about being broken into, so when looking at the door, the style and color of the door is more important.

Strong. Dendon security door has 6 lock points, all over the door frame on all sides, once the security door is locked, the 6 lock points are immediately blocked, to ensure the safety of the entire security door. And the three-dimensional lock core is adopted, the key cannot be copied, and the original three-dimensional special-shaped marble group is crossed in three rows and arranged in a dislocation.

Let me tell you about the use of the Deton security door for 4 years.

The fingerprint lock is completely broken because of the quality problem, after the warranty period, the after-sales service said, it will cost 2000 yuan to replace the lock, the warranty is 2 years, and it will continue to be replaced after 2 years. It's a pit.

If you buy this door, please forget that you have a fingerprint lock. There is a big problem with this smart hardware in his house. Use it as a normal security door.

This is the dialogue between the lock change and the after-sales service. It's literal. It cost 10,000 yuan to buy the door, and it takes 2k to change the lock, and it still needs to be replaced regularly.
