What is an invisible protective net?
Invisible protection net, also known as intelligent invisible anti-theft net, is a new building security product installed in windows, balconies and other places, which provides protection, anti-theft and anti-falling objects for home life and office. It is made of 2 mm thick stainless steel wire and tightly wound between the outer end faces of the window. Among them, the steel wire is a special 12+ 1 copper core conductor steel wire (protective conductor without copper core), and the copper core conductor is completely insulated from the outer steel wire layer, so it is impossible to make the copper core conductor communicate with the outer steel wire layer by burning or cutting. The steel wire spacing is fixed at 5CM, which can bear more than 85KG of tension and can ensure that thieves can't break it. Moreover, there is a spacing of 5CM between the steel wires, so people can't get into the gap, which plays a role in theft prevention. If a thief cuts or forcibly enters outside the doors and windows, the copper conductor in the steel wire will generate an open circuit signal, and the terminal alarm system will generate an alarm signal.
Five basic functions of invisible protective net

Disadvantages of invisible protective net
1, the anti-theft of this product mainly depends on the intelligent alarm system, so the alarm system must be kept in good condition at all times, and the battery should be replaced in time, otherwise the effect will be affected;
2, the installation quality requirements are high, improper installation will leave a security risk.
Invisible protective net literacy area
(1) Select the products of well-known enterprises. Well-known enterprises pay attention to brand cultivation and publicity, and the product quality is guaranteed. Because there is a binding mechanism such as market margin for agents, the market behavior is standardized, especially in the after-sales service of products, the rights and interests of consumers are guaranteed.
(2) Pay attention to the selection of special steel wire. The first factor that determines the quality of steel wire is the material of steel wire. At present, the steel wire with the best corrosion resistance on the market is 3 16 stainless steel wire, followed by 304 stainless steel wire. When the tensile strength of steel wire reaches 1000N, the finer the steel wire, the better.
(3) Pay attention to compare the installation quality. Be sure to make a field trip to the merchants before installation. First, judge the degree of standardized management of enterprises from the business premises; The second is to check whether there are various test reports of products and whether there is a complete enterprise management system, especially the installation operation procedures; Third, see if there is an overall installation project and check its installation quality on site.
(4) Don't unilaterally pursue low prices. We all like shopping. The cheaper the better. But while comparing the prices, we should not forget the quality of the products. We must pay attention to the quality when buying security products, because it is related to our property and personal safety.
How much is the invisible protective net?
The installation fee of invisible protective net is calculated in square meters, and the charging area = runway length * invisible protective window height. This calculation method is a common standard in the industry. The cost of the invisible protective net can vary according to the materials used and the regions, generally ranging from 120 to 150 yuan/square meter (including installation cost and material cost). If you are looking for a decoration team, the price can generally be cheaper.
Invisible protective net material
After knowing how much the invisible protective net costs, you also need to know the materials needed for decoration. A large part of the difference in the installation cost of the invisible protective net lies in this material. The required materials include aluminum, steel wires with diameters of 1.8 and 2.0MM, expansion screws, special steel wire positioning tensioners, rivets, alarms and connecting buckles. The main difference lies in aluminum and steel wire. Everyone should choose the diameter and model of steel wire according to their actual needs.
Install invisible protective net
The installation of invisible protective net is a very professional matter, so you must transfer to a professional installation team, and don't just find someone to install invisible protective net. After all, this is related to the safety of the home. The price of the invisible protective net has included the installation fee of the invisible protective net, so we don't have to pay the installation fee. The following small series introduces the steps of installing the invisible protective net for everyone:
1. The materials mentioned above need to be prepared before construction.
2. Measure the length and height of the balcony before construction, cut the length of aluminum alloy material according to the length of the balcony, calculate the building area according to the height and length, and calculate the required steel wire length.
3. Install the track, generally install the lower track first, which can be installed on the fence or on the floor. If the fence itself is made of glass, it is recommended to install it on the floor, while the fence is made of iron, aluminum alloy and stainless steel, which can be directly installed on the fence.
4. If the track is directly installed on the fence, stainless steel screws are generally used, the length is greater than 5 cm, and the screw spacing is controlled at 30 cm. If the track is installed on the floor, use expansion screws. The track at the ceiling position is fixed with expansion screws.
5. Pulling steel wire: fix one end of the steel wire on the first screw on the track of the invisible protective net, then wind the steel wire up to the first screw on the upper track, bypass the second screw, and then wind it down to the second screw on the lower track, and so on until all the screws are wound.
6. Position the tensioner with steel wire to tension the steel wire. The general practice is to pull the steel wire once from beginning to end, and then pull it one by one. After the invisible protective net is installed, it is necessary to ensure that the maximum distance between them is less than 7 cm.
7. If the balcony is too high, you can pull a steel wire horizontally in the middle, and then lock the horizontal and vertical steel wires with a cross buckle to increase the safety of the invisible protective net. If the height exceeds the use height of the cross buckle, it is necessary to reinforce the invisible protective net with large aluminum strips.
8. If necessary, an alarm device can be installed. Low-rise residents suggest that it must be installed. Invisible anti-theft net ensures home safety.
