A Brief Analysis of the Methods Needed for Selecting the Door Lock

There is a lack of doors in every home, and each door lacks matching locks. A matching lock can make the door more functional and have the finishing touch. However, if a door is not locked, security cannot be guaranteed. It may be that the lock is an integral part of the door. In the case of door locks, door locks, channel locks, bathroom locks, etc. are used according to the purpose, and ball locks, handle locks, and mortise locks are divided by shape. According to the use of the door locks, bedroom locks, channel locks, bathroom locks, etc.; according to the shape of ball-type lock, handle lock, mortise lock, lock and so on. Ball locks and handle locks have three functions: lock, handle, and touch ball. And you need to install a door handle separately. This requires a good door with a good lock, what kind of door with what kind of lock, but you know how to pick a good lock it? Nowadays, there are a wide variety of hardware locks on the market, and the similarity of styles has caused many ordinary consumers to have headaches. So how to pick a good hardware lock on the door, lock experts Fu Shili to give you support, and master the following four look very important.

First, look at the lock material The market's locks are basically divided into stainless steel, copper, zinc alloys, aluminum alloys and iron and other materials. Each of these materials has its own advantages and disadvantages. Stainless steel has high strength, strong corrosion resistance and does not change color. It is the best material for making locks, but its forging performance is not good. The style and color of stainless steel door locks are relatively simple. The copper material has superior mechanical properties and is generally used to make European high-grade door locks. The price and grade are relatively high. Zinc alloy has strong wear resistance, corrosion resistance and other properties, and is relatively easy to cast, can design a lot of styles and patterns, the current hot locks on the market are a lot of zinc alloy material. However, due to the difference in the ratio of zinc alloy and raw materials, and the different design process casting process, the price difference is very large. The use of aluminum alloy and iron is relatively small. The aluminum alloy is mainly made of aluminum. This type of door lock design is generally relatively simple, there is no pattern design, and iron-type door locks are now less and less, basically belong to the low-end door locks. There are many kinds of locks, and there are locks for different materials and grades. The main thing is to look at your own budget and style, choose a big brand, and the brand and quality are relatively guaranteed.

Second, look at the lock surface treatment The surface treatment of the lock can be broadly divided into three kinds: electroplating, spraying and coloring. The locks form a layer of dense protective film on the surface of the product through surface treatment, which can play a role in anti-corrosion and anti-rust, and make the lock more beautiful and durable. The dense protective film is also a measure of the quality of locks. Good quality locks are mostly plated. The coating is delicate and smooth, even and moderate, bright in color, free of bubbles, signs of rust and oxidation. For instance, the hardware products of Tiannu hardware are all through layer plating process and road polishing process, 48-hour moderate salt spray test or 200-hour low-level salt spray test to ensure that the product surface does not appear spotted and oxidized on the surface due to use and time lapse. Rusty.

Third, look at many types of key keys, generally divided into a word key (ordinary keys and angle keys), cross keys, computer keys, cylinder keys, etc., different key configuration of the lock key is not the same, the ordinary one-word key The price of door locks with cross key configuration is relatively cheap, but the anti-theft performance is relatively poor, belonging to A-level door locks. As the anti-theft performance is relatively low, the public security department vigorously promotes the use of Class B and Class C. These two types of door locks have a relatively high manufacturing process. The more complex the patterns of the keys, the lower the chance of successful imitation, and some brands such as Tenuta Hardware. Luxury door locks have a unique password card, if the new key must be assigned to a designated professional institution with a password card to enable key matching, which greatly improves anti-theft performance.

Fourth, to see the implementation of standards for locks Hardware locks abroad have very strict standards and regulations, so the quality of imported products is relatively high. We can feel the locks by hand. In general, the feeling of heavy locks, the quality is relatively high; the lock body can not be exposed, the exposed point is easy to hurt, in particular, should pay attention to the lock handle end of the lock, the lock tongue and the lock body four positions; lock spring good locks Flexible opening, high sensitivity and long service life. Locks also have a variety of styles, and must be consistent with the style of the interior doors.
