Every home has its own door, and every door has its own matching lock. A matching lock can make the door more perfect function, with the finishing touch. However, if a door is not locked, then the security can not be guaranteed, it can be a lock is an integral part of the door. In terms of door locks, according to the purpose of sub-door lock, channel locks, bathroom locks, according to the shape of sub-ball lock, handle lock, mortise lock. According to the purpose of sub-door locks, bedroom locks, channel locks, bathroom locks, etc.; according to the shape of sub-type lock, handle lock, mortise lock, sluggish lock. Ball lock and handle lock with a lock, handle and touch the ball three functions. And stay locked to install the door handle. 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? Now on the market, a wide range of hardware locks, similar style high, so many ordinary consumers is a headache. So how to pick the door hardware lock it, the lock expert expert force to give you Weapon, grasp the following four is very important.

First, see the locks on the market The lock is basically divided into stainless steel, copper, zinc alloy, aluminum and iron and other materials. Each of these materials has its own advantages and disadvantages. Stainless steel high strength, corrosion resistance, does not change color, is the best lock material, but forging performance is not good, stainless steel door lock style and color is relatively simple. Superior mechanical properties of copper materials, generally used to make European-style high-grade door locks, the price and grade are relatively high. Zinc alloy with strong wear resistance, corrosion resistance and other properties, and relatively easy to cast, you can design a lot of styles and patterns, the market is currently selling a lot of zinc alloy material are lock. However, due to different zinc alloy ratio and raw materials, and the design process casting process, resulting in a great price difference. Aluminum and iron applications less aluminum alloy is mainly space aluminum, this type of door lock design are generally more simple, there is no pattern design, iron door locks are now less and less, basically belong to the low-end door locks. More types of locks, locks of different materials and grades have, mainly to see their own budget and style, choose a big brand, brand and quality are more assured.

Second, see the lock surface treatment Lock surface treatment is roughly divided into three kinds of electroplating, spraying and coloring, the surface of the lock through the formation of a dense protective film on the product surface, play a role in preservative and rust-proof, so lock more beautiful and durable. Dense protection film is also a measure of the quality of locks, good quality locks, the use of electroplating treatment, smooth and delicate coating, uniform moderate, bright color, no bubbles, rust and oxidation signs. If the days of hardware products are through the layer plating process and Road polishing process, 48 ​​hours of moderate salt spray test or 200 hours of low salt spray test to ensure that the product surface due to the use and passage of time on the spot and oxidation Rusty.

Third, look at the 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 lock key is not the same, ordinary word key And the cross key configuration lock price is relatively cheap, but relatively poor anti-theft performance, belonging to A-class locks. Because the anti-theft performance is relatively low, the public security department vigorously publicize the use of Class B and Class C, these two types of door locks manufacturing process is relatively high, the more complex the key pattern, the less likely the success of imitation, and some brands such as Tianyu hardware Luxury door locks have a unique password card, if equipped with a new key card with a designated professional agencies can be equipped with a key card, greatly improved anti-theft performance.

Fourth, look at the implementation of the standard locks Foreign metal locks have very strict standards and regulations, so the quality of imported products is relatively higher. We can feel the lock by hand. In general, the feeling of heavy locks, relatively high quality; lock body can not be exposed, the tip is easy to hurt, in particular, should pay attention to lock the end of the lock handle, bolt and lock body three corners; lock a good lock Open flexible, high sensitivity, long service life. Locks also exist a variety of styles, we must pay attention and the style of the interior door consistent.
