Many people have no doors in their homes, and each door has no matching locks. A matching lock can make the function of the door more perfect, have the finishing touch effect. But if a door is not locked, then security can not be guaranteed, can be a lock is an essential part of the door. As far as the door lock is concerned, it is divided into door crack lock, channel lock, bathroom lock, etc. according to the purpose, and spherical lock, handle lock, mortise lock, etc. according to the shape. According to the purpose of the door lock, bedroom lock, channel lock, bathroom lock, etc.; according to the shape of the ball lock, handle lock, mortise lock, lock and so on. Ball lock and handle lock with lock, handle and touch the ball three functions. And the lock to install another door handle.
This requires a good door with a good lock, what kind of door with what kind of lock, but do you know how to pick a good lock. So how to choose a good door hardware locks, lock experts to give you advice, master the following four look is very important.
1. look at the lock material
The locks on the market are basically divided into stainless steel, copper, zinc alloy, aluminum alloy and iron and other materials. Each of these materials has its own advantages and disadvantages.
Stainless steel has high strength, strong corrosion resistance, and no discoloration. It is a good lock-making material, but the forging performance is not good. The style and color of stainless steel door locks will be relatively single. Copper material has good mechanical properties and is generally used to make European-style high-end door locks, with relatively high prices and grades. Zinc alloy has strong wear resistance, corrosion resistance and other properties, and relatively easy to cast, can design many styles and patterns, currently on the market to sell many good locks are zinc alloy material. However, due to the different ratio and raw materials of zinc alloy, and the design process of casting process is different, resulting in a great difference in price. Aluminum alloy and iron applications are relatively few, aluminum alloy is mainly space aluminum, this kind of door lock design is generally relatively simple, no pattern design, iron door lock is now less and less, basically belongs to the low-end door lock. There are many types of locks, different materials and grades of door locks are available, mainly to see their own budget and style, choose a big brand, brand and quality are relatively guaranteed.
2. look at the lock surface treatment
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 plays the role of anti-corrosion and anti-rust, making the lock more beautiful and durable. Dense protective film is also a measure of the quality of the lock standard, good quality locks, the use of electroplating treatment, the coating is fine and smooth, uniform and moderate, bright color, no bubbles, rust and signs of oxidation. For example, Tiannu hardware products are all subjected to layer electroplating process and polishing process, 48 hours of moderate salt spray test or 200 hours of low salt spray test, and the surface of the products will not be spotted and oxidized and rusted due to use and the passage of time.
3. look at the key.
There are many types of keys, generally divided into one-word keys (ordinary keys and angle keys), cross keys, computer keys,
Cylindrical keys, etc., door lock keys with different key configurations are different. Ordinary one-word keys and cross-key door locks are cheaper, but the anti-theft performance is relatively poor, and they are good door locks. Due to the relatively low anti-theft performance, 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 complex the pattern of the key, the smaller the chance of success in imitation. Some brands such as Tiannu Hardware Luxury door locks have a good combination card. If a new key is matched, the key must be matched with a designated professional organization, thus greatly enhancing the anti-theft performance.
4. look at the lock implementation standard
Foreign hardware locks have very strict standards and regulations, so the quality of imported products is relatively high. We can feel the good or bad of the lock with our hands. Generally speaking, the quality of heavy locks is relatively high. The lock body cannot be exposed, which is easy to hurt people. Special attention should be paid to the three positions of the end of the lock handle, the bolt and the four corners of the lock body;
A good lock spring has flexible opening, high sensitivity and long service life. Locks also exist in a variety of styles, be sure to pay attention to consistent with the style of the interior door.
