Handle With Lock

Choose a good door lock, you need to master four methods

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 part of the door. Door locks are divided into door locks, channel 

locks, bathroom locks, etc. according to the purpose, and are divided into spherical locks, handle 

locks, mortise locks, etc. according to the shape. According to the purpose, the portal lock, 

bedroom lock, channel lock, bathroom lock, 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.

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, we have the following four methods for reference.

1. 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 a good lock 

material, but its forging performance is not good. The style and color of stainless steel door locks 

are relatively simple. The copper material has good 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. It is easy to cast and can be 

designed in many styles and patterns. Many of the better locks on the market are made of zinc 

alloy. The ratio of zinc alloy to raw materials is different from that of the design process, resulting 

in a large price difference. 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. There are different materials and grades of door locks. It is to look at your own budget 

and style. Choose a big brand, brand and quality are guaranteed.

2. Look at the surface treatment of locks.

Surface treatment of locks can be divided into electroplating, spraying and coloring. Locks form a 

dense protective film on the surface of products through surface treatment, which plays an anti-

corrosion and anti-rust role and makes locks more beautiful and durable. Close protective film is 

also a standard to measure the quality of locks, good quality locks, more use of electroplating 

treatment, coating fine and smooth, uniform and appropriate, bright color, no bubble, rust and 

oxidation signs. For example, Tiannu hardware products are polished by layer plating process and 

channel polishing process, 48 hours of moderate salt spray test or 200 hours of low salt spray test, 

so that the surface of the product does not due to use and time lapse on the spot and oxidation 

rust.

3. Look at the key

There are many kinds of keys, generally divided into one-word keys (ordinary keys and angle keys), 

cross keys, computer keys,

Cylinder keys and so on, the different key configurations door lock key is different, the ordinary 

one-word key and the cross key configurations door lock price is relatively cheap, but theft-proof 

performance is poor, belongs to the good door lock. Because theft-proof performance is relatively 

low, public security departments publicize the use of B-class and C-class, the manufacturing 

process of these two types of door locks is relatively high, the more complex the pattern of the key, 

the less the chances of success of imitation, some brands such as Tiannu hardware luxury door 

locks have a good password card, if the new key must rely on the password card to the finger. 

Professional institutions can only match key, which greatly improves the anti-theft performance.

4. Look at the lock implementation standards

Foreign countries have very strict standards and regulations for hardware locks, so the quality of 

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 

people. Attention should be paid to 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.
