Every home is indispensable with doors, and every door is indispensable with matching locks. A matching lock can make the function of the door more perfect and add the finishing touch. But if a door does not have a lock, then security cannot be guaranteed, because the lock may be part of the door. Door locks are divided into door seam locks, passage locks, bathroom locks, etc. according to their uses; they are divided into ball locks, handle locks, mortise locks, etc. according to their shapes. According to the use, they are divided into door locks, bedroom locks, passage locks, bathroom locks, etc.; according to the shape, they are divided into ball locks, handle locks, mortise locks, dead locks, etc. Ball locks and handle locks have three functions: lock, handle and ball. Dead locks require additional door handles.
This requires a good door with a good lock, and what kind of door goes with what kind of lock. But do you know how to choose a good lock? Nowadays, there are many types of hardware locks on the market, and the styles are highly similar, which makes many ordinary consumers Very headache. So how to choose a good door hardware lock? Lock expert Fu Shili is here to give you some advice. It is important to master the following four things.
1. Look at the lock materials
Locks on the market are basically divided into several materials such as 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 does not discolor. It is a good lock-making material, but its forging performance is not good. The styles and colors of stainless steel door locks are 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 is strong, wear-resistant, and corrosion-resistant. It is relatively 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 and raw materials of zinc alloy are different, as well as the design process and casting process, resulting in great price differences. Aluminum alloy and iron are rarely used. Aluminum alloy is mainly space aluminum. The design of this type of door lock is generally relatively simple, without pattern design. Iron door locks are becoming less and less now, and they are basically low-end door locks. There are many types of locks, and door locks of different materials and grades are available. It depends on your budget and style and choose a big brand. The brand and quality are more guaranteed.
2. 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 plays an anti-corrosion and anti-rust role, making the locks more beautiful and durable. The dense protective film is also a standard for measuring the quality of locks. Good-quality locks are often electroplated. The coating is fine, smooth, uniform and moderate, with bright color and no signs of bubbles, rust or oxidation. For example, Tino Hardware's products undergo a layer of electroplating process and a state-of-the-art polishing process, and undergo a 48-hour moderate salt spray test or a 200-hour low salt spray test to prevent spots and oxidation on the surface of the product due to use and the passage of time. rust.
3. Look at the keys
. There are many types of keys, generally divided into flat keys (ordinary keys and angle keys), cross keys, computer keys,
cylindrical keys, etc. Door lock keys with different key configurations are different. Ordinary flat keys Door locks equipped with cross keys are relatively cheap, but their anti-theft performance is relatively poor, so they are good door locks. Due to the relatively low anti-theft performance, the public security department promotes the use of Class B and Class C door locks. 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 successful counterfeiting. Some brands such as Tiannu Hardware are luxurious The door locks all have a good password card. If you want to get a new key, you must go to a designated professional institution with the password card to get the 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 the products is relatively high. We can feel the quality of the lock with our hands. Generally speaking, locks that feel thick and heavy are of relatively high quality; the lock body cannot be exposed, as it can easily hurt people. Pay attention to the end of the lock handle, the lock tongue and the four corners of the lock body;
when opening a lock with a good lock spring , Flexible, high sensitivity and long service life. There are also many styles of locks, so be sure to keep them consistent with the style of the interior door.
