Every home has a door, and every door has a matching lock. A matching lock can make the door more perfect and has the finishing touch. However, if a door is not locked, security cannot be guaranteed, and the lock can be an indispensable part of the door. As far as the door lock is concerned, the door lock, the channel lock, the bathroom lock, etc. are divided according to the purpose, and the ball lock, the handle lock, the mortise lock, and the like are divided according to the shape. According to the purpose of the portal lock, bedroom lock, channel lock, bathroom locks, etc.; according to the shape of the ball type lock, handle lock, mortise lock, lock and so on. The ball lock and handle lock have three functions: lock, handle and ball touch. The lock is to be additionally installed with a door handle.
This requires a good door with a lock, what kind of door is equipped with a lock, but do you know how to pick a good lock? Nowadays, there are many kinds of hardware locks on the market, and the style is similar, so many ordinary consumers Very headache. So how to choose the hardware lock on the door, the lock expert to give you a trick, it is very important to master the following four.
First, look at the lock material
The locks on the market are basically divided into stainless steel, copper, zinc alloy, aluminum alloy and iron. Each of these materials has its own advantages and disadvantages.
Stainless steel has high strength, strong corrosion resistance and no discoloration. It is the best lock material, but its forging performance is not good. The style and color of stainless steel door locks are relatively simple. Copper material has superior mechanical properties and is generally used to make European-style high-grade door locks. The price and grade are relatively high. Zinc alloy has strong wear resistance, corrosion resistance and other properties, and it is easy to cast. Many styles and patterns can be designed. Many of the hot locks on the market are made of zinc alloy. However, due to the different ratios and raw materials of the zinc alloy and the different casting processes of the design process, the price difference is great. Aluminum alloy and iron are used less, and aluminum alloy is mainly space aluminum. The design of such door locks is generally simple. Without pattern design, iron door locks are now less and less, basically belonging to low-end door locks. There are many types of locks, and the locks of different materials and grades are mainly based on their own budget and style. The choice of big brands, brand and quality are more guaranteed.
Second, look at the surface treatment of the lock
The surface treatment of locks is roughly divided into three types: electroplating, spraying and coloring. The locks form 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. Ruthen Hardware's products are subjected to a layer plating process and a polishing process, a 48-hour moderate salt spray test or a 200-hour low-level salt spray test to ensure that the surface of the product is not spotted and oxidized by use and time lapse. Rusty.
Third, look at the key
There are many types of keys, which are generally divided into a single key (ordinary key and angle key), a cross key, a computer key,
Cylindrical keys, etc., the key lock keys of different key configurations are different. The common one-key and the cross-key configuration are relatively cheaper, but the anti-theft performance is relatively poor, belonging to the A-level door lock. Because the anti-theft performance is relatively low, the public security department vigorously promotes the use of Class B and Class C. The manufacturing process of these two types of door locks is relatively high. The more complicated the pattern of the keys, the smaller the chance of success in copying. Some brands such as Tiannuo Hardware The luxury door locks have a unique password card. If a new key is required, the password card must be used to assign a key to a designated professional organization, which greatly improves the anti-theft performance.
Fourth, look at the lock implementation standards
Foreign countries have very strict standards and regulations for hardware locks, so the quality of imported products is relatively high. We can feel the quality of the lock by hand. Generally speaking, the weight of the lock is relatively high; the lock body can not be pointed, and the tip is easy to injure, especially the lock handle end, the lock tongue and the four corners of the lock body;
The lock spring has a flexible opening, high sensitivity and long service life. There are also many styles of locks, so be sure to keep in mind the style of the interior doors.
