There are many kinds of hardware lock materials on the market, the style is very similar, the processing technology is diverse, and the specifications are not the same. The average consumer has taken the eye. So how to choose the hardware lock on the door, now the best skills for you to sort out the hardware locks.

A look at the lock material

The lock material on the market is 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. Generally, some relatively large brands such as Huitailong and Tiannuo hardware have more types of locks. The locks of different materials and grades are mainly based on their own budget and style. The choice of big brands, brands and quality are more Guarantee.

Second, look at the surface treatment of the lock

The surface treatment is roughly divided into 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. Ru Tiannuo's products are subjected to a 12-layer plating process and an 8-pass polishing process, a 48-hour medium salt spray test or a 200-hour low-level salt spray test to ensure that the surface of the product is not spotted due to use and time lapse. And oxidized rust.

Three to see the key

There are many types of keys, generally divided into a single key (ordinary key and angle key), a cross key, a computer key, a cylindrical key, etc. The key lock keys of different key configurations are different, the ordinary one-key and the cross key configuration The price of the door lock is relatively cheap, 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.

Four 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 heavy lock has a relatively high quality; the lock body can not be pointed, and the tip is easy to injure, especially the lock handle end, the lock tongue and the lock body are three positions; the lock spring is good. 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.

Door lock is the first line of defense for home security. The purchase of door locks is not sloppy. Many people now buy door locks, but they are generally door locks with low grade and anti-theft performance. It is recommended that for safety, everyone will re- Buy brand door locks, such as Yajie Hardware, Huitailong and Tiannu Hardware, brand, quality and safe use are guaranteed.
