"Three notes" for hardware locks
First, pay attention to the lock material
The lock materials on the market are basically divided into stainless steel, copper, zinc alloy and the like. High-strength stainless steel, strong corrosion resistance, no discoloration, is the best lock material; copper is more versatile, mechanical properties are superior, and the price is higher; the lock high-quality zinc alloy is strong and wear-resistant, corrosion-resistant, and easy to form. Mostly used for mid-range locks. When choosing, if you consider the cost performance of ordinary living locks, it is recommended to consider zinc alloy locks.
Second, pay attention to the surface treatment of the lock
The surface treatment of the lock is roughly divided into three types: electroplating, spraying and coloring. The lock forms a dense protective film on the surface of the product through surface treatment, which acts as anti-corrosion and anti-rust, making the lock more beautiful and durable. The dense protective film is also a standard for measuring the quality of locks. The quality of the locks is mostly electroplated, the coating is fine and smooth, even and moderate, the color is bright, and there are no signs of bubbles, rust and oxidation. The surface treatment of the lock is not only for the sake of beauty, but also relates to the service life and quality of the lock. Therefore, for a good lock, the surface treatment must be passed.
Third, pay attention to the implementation standards of locks
Foreign countries have very strict standards for hardware locks, so the quality of imported products is relatively high. And domestic hardware locks, we must pay attention to its certificate and implementation standards when purchasing, under certain circumstances, choose relatively well-known big brand locks, the quality is relatively more assured. In addition to these, we can also feel the quality of the lock by hand. Generally speaking, the weight of the lock is relatively good, and the lock body can not be exposed. The tip is easy to hurt. In particular, pay attention to the lock handle end, the lock tongue and the lock body. The lock spring is good. The locks are flexible to open, high in sensitivity and long in service life.
In addition, in the selection of hardware locks, especially indoor door locks, in addition to the quality of the locks, the style of the locks is also relatively important, it is best to choose a door lock that is consistent with the style of the interior door.
