As soon as the winter solstice took place, the temperature became very low as soon as the winter arrived, and people's reactions also became somewhat dull. Together with the New Year, the thief, a thieves who could not be reached, began to prepare for the “new yearâ€. Fire and theft prevention was particularly important in winter. . The first thing that comes to mind is to pick a good door, so how do you choose a security door? For everyone's personal and property safety, next to tell you the security door selection techniques. First, look at the level of security doors The higher the safety level, the thicker the steel plate Anti-theft door national security standard for security door products is divided into "A", "B", "C", "D" 4, A is the highest level, followed by decreasing, respectively, "J", "Y", "B "," "D" to indicate that the thickness of the door frame steel plate corresponding to 2mm, 2mm, 1.8mm and 1.5mm. Locking points for security level It can be seen from the anti-destruction time and the locking point that the anti-theft door grade is qualified. Class A security door> 30 minutes, the locking point between the door frame and the door leaf> 12; B> 15 minutes, the locking point> 10; C> 10 minutes, the locking point> 8; D> 6 Minutes, lock points >6. The same level, the heavier and safer If the same level, the greater the weight, the more lock points, the more dense steel skeleton, the more security protection of the locks, the quality is relatively good. Since it is difficult to see the skeleton of the security door, the owner can refer to the product section (profile) provided by the dealer and can also judge from the weight. In general, the greater the weight, the denser the internal steel skeleton and the more secure and secure the door. Second, look at the lock point, not as much as possible As some manufacturers do publicity at the lock point, customers feel that the more lock points the better, and the unknown factory locks all reach fifteen or six. Today I would like to say that the more lock points are not better, the security door can only be locked in three directions, ie side and up and down. The more lock points, the more chance of failure, and in case there is a problem with which lock point, the door may not be opened. From an anti-theft point of view, all the lock points are controlled by one place, and there is no more meaning to them. Choose a lot of security doors for good sales, in the side also added a lock up and down, in fact, this is really not much use, but it is easy to cause failure, do not have to go to buy more than a few lock points. Third, watch the filler A good product has a steel skeleton in the door leaf, filled with polyurethane foam or fire retardant, poor product filled with honeycomb paper, no skeleton, detection methods: open the cat's eye to see it, and now there are individual manufacturers will fill in the cat's eye extension, Then, as stated in the contract, the filler is required to be stretched, and the keyhole can be detected before installing the door handle. Fourth, look at the wall thickness of security doors In general, the thicker the steel plate is, the better the quality of the anti-theft door is, and the minimum standard of the country's anti-theft door plate thickness is 1.5 mm. To determine the thickness of a steel plate, the easiest way is to “push and push itâ€: Push the door, the thick steel door pushes hard, the thin one is lighter, and the knocking door sounds thick and boring. , crisp, empty, it should be fake. Panpan's anti-theft door is made of high-quality cold-rolled steel. The thickness of the door frame and the door leaf are 2mm and 1mm, respectively. The steel plate is thick and pushes hard. Fifth, look at the level of the cylinder Anti-theft door locks are divided into A-level locks and B-level locks, as well as Super B-level, this time based on the technical opening and destructive opening time, the specific time of a Baidu will know, I am not here. Suggest that you can choose B-level, you can not judge, let the seller write the lock on the contract for the B-level. Six, see the security door specifications Anti-theft door to pass the quality, size and appearance should also meet the needs of the home, do not forget to forget the importance of matching the space with the size of the space. There are four types of security doors in general, with heights of 2050mm and 1970mm, and widths of 860mm and 960mm, which can be combined with each other. When you purchase, you must consider setting a margin of about 20mm for easy installation and adjustment.
