Door and window hardware accessories look the same as locks

Due to different materials and workmanship, the price of locks ranges from a dozen yuan to several hundred yuan. At present, the lock cylinders in the market are divided into A grade, B grade, super B grade and so on. Consumers can identify the quality of the lock cylinder by the number of marbles. In general, multi-row marble locks are superior to single-row marble locks, and multiple-row stealth marble locks are superior to ordinary multi-row marble locks. According to the manager of Jiangnan Hardware Store, the cost of the B-class lock core is much higher than that of the A-class lock core. Therefore, most of the lock brands launched in the market are A-class locks. If the security door key has only one row of marbles, it is basically a Class A lock cylinder. If you feel that it is not safe enough, you can replace it with a B-class or Super-B lock cylinder to improve the overall anti-theft performance of the security door.

In addition to the lock cylinder, the quality of the hardware is also critical. The material of the lock is generally aluminum alloy, Stainless Steel and copper. Among them, the strength and durability of the aluminum alloy are the worst, and the copper is the best, but the price is also high. The same is the copper lock, the workmanship and quality of each brand are also very different, it is difficult for ordinary consumers to distinguish. The only way for consumers to buy a lock is to compare. The locks of big brands are very fine, and the joints are tight. The work of low-end locks will look rough. It is understood that brand locks are favored by more and more businesses and consumers.
