Look at the anti-theft tag
The country has a unified definition of the security level of the security door, a total of "A, B, and D" four levels, the best class A, and so on. However, there are only a few Class A security door products on the market. Take this 27-type metal wood carving panpan anti-theft door as an example, it belongs to Panpan door industry in high-end products, anti-theft level is B, "B" mark engraved on the top of the door frame, circled with a circle, many "cottage version" Security doors do not have such a sign. When picking at the scene, you can ask the salesman to open the door and see if there is a rating mark on the left side of the door frame.
Second look at the plate thickness
In general, the thicker the steel plate is, the better the quality of the anti-theft door is. 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.
Three to see the lock
The door lock is a key part of the security door. To distinguish whether the door lock is good or not, first look at the number of the lock control plug, and it is generally better to control the 2 plugs for each of the 2 locks. Anti-theft locks are divided into two grades: a and b, which means that professional locksmiths can open the door in less than 1 minute and 5 minutes.
Four look filler
Good anti-theft door stuffing has the functions of heat preservation, fire prevention, sound insulation, etc. It not only can be more safe but also can protect the door leaf, and it can better protect privacy. This 27-type metal wood panpan anti-theft door uses high-quality aluminum silicate rock wool as the filler of the steel plate sandwich. The regular security doors currently on the market are mainly filled with rock wool or honeycomb paper. The “cottage version†security door will be filled with ordinary cardboard or inferior cotton. So at the time of purchase, you can ask the salesman to open the cat's eyes, doorbell box, or handles to see what is inside.
In addition to the above 4 points, the price can also be used as a standard to judge the quality of security doors. Due to the high cost of security doors, in general, even if it is a single door, it must be 800 yuan. Therefore, you can ask the price before buying. If it is less than 800 yuan, then most of the quality is not good. In addition, it is best to buy a security store to find a regular store, and ask the sales staff for an invoice.
