As the saying goes, we have a house before we have a home. Sometimes we put some expensive things in our home, so now we need a better security door. The security door has a variety of products, and the price of the security door is not the same, which makes people see things in a blur. Xiaobian brings you an introduction about the price and brand of the security door, hoping to provide some reference for the majority of netizens. Next, let's take a look at it with Xiaobian.

1. Introduction to the price of security door

1. Regarding the price of security door, it is not a fixed price, mainly depending on the brand, grade, quality, material, thickness and local consumption of security door, which are all important factors affecting the price. When you choose, you can go shopping at

and choose a brand with high cost performance and high quality.

2, the price of security doors is generally very small. The price of ordinary security doors is about 1-15 yuan, and the middle price is about 2-26 yuan. The slightly better price is more than 3 yuan, or even more expensive. You can choose the right price according to your own budget and actual situation, and don't blindly pursue it.

second, the security door selection skills

1. The country has a unified definition of the security level of the security door. * * * Set "A, B, C and D" level 4, with Grade A being the best, and so on. However, there are quite few Grade A security door products on the market now. Take this 27-type metal wood carving Panpan security door as an example. It belongs to the high-end product of Panpan door industry, and its security level is Grade B. The symbol "B" is engraved on the top of the door frame and circled in circles. Many "cottage version" security doors do not have this symbol. Many "fake" security doors do not have this type of sign. When shopping on the spot, we can ask the salesperson to open the door, and there is no rating on the left side of the door frame.

2. Generally speaking, the thicker the steel plate is, the better the quality of the security door. The minimum thickness of the security door is 1.5mm.. The simplest way to judge the thickness of steel plate is to "push and knock": push the door, the thick security door of steel door pushes hard, thin and light; Knock on the door, the sound is thick, dull and firm. It's crisp and empty, so it's probably fake. Panpan's security door adopts high-quality cold-rolled steel plate. The thickness of door frame and door leaf is 2mm and 1mm respectively. The steel plate is thick and difficult to push.

3. The door lock is the key part of the security door. To distinguish the quality of the door lock, first look at the number of lock control plugs. Generally, it is better to control two plungers for each of the two locks. Anti-theft locks are divided into two grades: A and B, which means that professional locksmiths can open the door for no less than 1 minute and 5 minutes.

4. Panpan's security door is equipped with a newly developed patented lock-Xiaoshuai lock body+super B-class Manshen lock core, which has the best security performance. It is said that it takes 4 hours to open, and the mutual opening rate is almost zero. However, the performance of the lock is better, and anti-theft also brings some inconvenience to everyone. If many users of the security door respond, the lock is too complicated and sometimes it is particularly troublesome to be accidentally locked by the shackle.

5. Good anti-theft door filler has the functions of heat preservation, fire prevention and sound insulation, which is not only safer, but also protects the door leaf and privacy. This 27-type metal wood carving Panpan security door adopts high-quality aluminum silicate as the filler of steel interlayer. Conventional security doors sold in the market are mainly filled with rock wool or honeycomb paper. The "cottage version" of the security door will be filled with ordinary cardboard or inferior cotton. Therefore, when you buy, you can ask the salesperson to open the cat's eye, doorbell box or handle and other places to see what's inside.

3. Brand of security door

1. Panpan is a very popular product in China. It is one of the top ten brands of security doors. It is the choice of China brand products. Generally speaking, Panpan security doors are relatively cost-effective, and people choose most of them.

2. Feiyun is also a very famous brand of security door. Feiyun is a famous brand product in Harbin, which has certain strength in the production of doors.

3. Wang Li, a well-known trademark in China, a brand in China, a first-line brand, Yongkang in Zhejiang, and Wang Li Group Co., Ltd. in China, the security door of Wang Li is exquisitely processed and has excellent quality, and its performance is more outstanding than that of other brands.

4. Qunsheng, a well-known trademark in China, a leading brand in the industry, a large-scale residential supplier, and the door industry of the drafting unit of national environmental protection standards, has a very good brand reputation and is well received by the public. Qunsheng is a popular brand, and its price is slightly lower than other similar brands.
