The proportion of copper doors in the market is higher and higher, and many consumers are also very confident in the quality of products. In general, it is relatively unified. Many copper door manufacturers also attach great importance to their own products, which are relatively guaranteed in terms of quality and carving technology. When people buy copper doors, they usually only pay attention to the copper doors themselves and ignore their accessories. For example, the door lock, but many people do not consider the details, resulting in the purchased products can not be used. So, what should we pay attention to when choosing locks for Shandong copper doors?

1、看锁的材质

1. Look at the material of the lock

市场上的门锁基本上分为不锈钢、铜、锌合金、铝合金、铁等材料。这些材料各有优缺点。

The door locks on the market are basically divided into stainless steel, copper, zinc alloy, aluminum alloy, iron and other materials. Each of these materials has its advantages and disadvantages.

不锈钢强度高，耐腐蚀性强，不变色。这是一种很好的制锁材料，但锻造性能不好。不锈钢门锁的款式和颜色相对单一。铜材料具有优越的机械性能。一般用于制作欧式门锁。和档次都比较高。锌合金具有很强的耐磨性、耐腐蚀性等性能，且相对容易铸造。它可以设计许多样式和图案。目前，市场上很多流行的锁具都是锌合金制成的。然而，由于锌合金的比例和原材料不同，设计工艺和铸造工艺不同，差异很大。铝合金和铁很少使用。铝合金主要是航天铝。这种门锁的设计一般比较简单，没有图案设计。铁门锁现在越来越少了，基本上属于低端门锁。锁有很多种。有不同材质和等级的锁。这主要取决于你的预算和风格。如果你选择一个大，和质量是相对有保证的。

Stainless steel has high strength, strong corrosion resistance and no discoloration. This is a good lock material, but its forging performance is not good. The style and color of stainless steel door lock are relatively single. Copper material has superior mechanical properties. It is generally used to make European door locks. Prices and grades are quite high. Zinc alloy has strong wear resistance, corrosion resistance and other properties, and is relatively easy to cast. It can design many styles and patterns. At present, many popular locks on the market are made of zinc alloy. However, due to different proportions of zinc alloys and raw materials, different design processes and casting processes, the prices vary greatly. Aluminum alloys and iron are rarely used. Aluminum alloy is mainly aerospace aluminum. The design of this kind of door lock is generally simple without pattern design. There are fewer and fewer iron door locks. They are basically low-end door locks. There are many kinds of locks. There are locks of different materials and grades. It depends on your budget and style. If you choose a big brand, the brand and quality are relatively guaranteed.

2、看钥匙

2. Look at the key

钥匙有很多种，一般分为一字钥匙(普通钥匙和角度钥匙)、十字钥匙、电脑钥匙、圆柱钥匙等。不同钥匙配置的大门锁钥匙是不一样的，普通的一字钥匙和十字钥匙配置的门锁相对比较便宜，但防盗性能比较差，属于A级大门锁。由于防盗性能比较低，公安部门大力宣传大家使用B级和C级，这两类大门锁的制造工艺比较高，钥匙的花纹越复杂，仿造的成功的几率越小，有些如富宇门锁的豪华大门锁都有一个的密码卡，假如配新钥匙需要凭借密码卡到指定机构才能配钥匙，大大的提高了防盗性能。

There are many kinds of keys, generally divided into word keys (ordinary keys and angle keys), cross keys, computer keys, cylinder keys, etc. The door lock keys configured with different keys are different. The price of the door lock configured with ordinary one word key and cross key is relatively cheap, but the anti-theft performance is relatively poor. It belongs to A-level large door lock. As the anti-theft performance is relatively low, the public security department vigorously publicizes 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 key pattern is, the less likely the imitation will be successful. Some brands, such as the luxury door locks of Fuyu door locks, have a password card. If new keys are equipped, they need to rely on the password card to the designated institution, which greatly improves the anti-theft performance.

3、看锁的表面处理

3. Surface treatment of lock

门锁的表面处理大致分为电镀、喷涂和着色。锁通过表面处理在产品表面形成一层致密的保护膜，起到防腐防锈的作用，使锁更加美观耐用。密集的保护膜也是衡量锁具质量的标准。质量好的锁大多是电镀的。涂层细腻光滑，均匀适中，色泽鲜艳，无气泡、锈蚀、氧化迹象。五金产品都经过了镀层工艺和抛光工艺，48次中盐雾试验或200次低盐雾试验，以确保产品表面不会因使用和时间的推移而出现氧化和生锈。

The surface treatment of door locks can be roughly divided into electroplating, spraying and coloring. The lock forms a dense protective film on the product surface through surface treatment, which plays a role in corrosion prevention and rust prevention, making the lock more beautiful and durable. Dense protective film is also the standard to measure the quality of locks. Locks of good quality are mostly electroplated. The coating is fine and smooth, uniform and moderate, bright in color, without bubbles, corrosion and oxidation. All hardware products have undergone coating process and polishing process, 48 medium salt spray tests or 200 low salt spray tests to ensure that the product surface will not be oxidized and rusted due to use and the passage of time.

4、看锁具执行标准

4. See the lock implementation standard

国外对门锁有非常严格的标准和规定，所以进口产品的质量相对较高。我们可以用手感觉到门锁的质量。一般来说，重锁的质量相对较高;锁体不应露出尖，容易伤人。尤其要注意锁柄末端、锁舌和锁体四角的三个位置。

Foreign countries have very strict standards and regulations on door locks, so the quality of imported products is relatively high. We can feel the quality of the door lock with our hands. Generally speaking, the quality of re locking is relatively high; The lock body shall not expose the tip, which is easy to hurt people. Pay special attention to the three positions of the end of the lock handle, the lock tongue and the four corners of the lock body.
