Consumers should consider the following aspects before purchasing a lock. Consumers must first determine where the locks are used, such as the bathroom, living room or bedroom.
1. The place used and its importance. That is, consider using it on a street front door, hall door, room, bathroom or passageway to select a product that suits the desired function.
2. The environment, conditions and requirements for use. You should consider the advantages and disadvantages of the use of the environment, such as dry humidity, door structure, thickness, left or right door, inner door or outer door to prevent the wrong product.
3. Consider coordination with the decorative environment. According to your own preferences, the product should be considered for coordination and matching with its living room.

In combination with the family's economic situation, the economy can afford to buy high-end products, and the economy is less than ideal, and the products with lower grades can be selected. However, regardless of whether high-grade or low-grade products are selected, it is necessary to consider whether the strength of the production enterprises is strong and whether the quality is stable. It is recommended to choose products with quite well-known companies to avoid causing financial losses and unnecessary troubles and troubles for daily life.
6, consider the dealer's reputation and service standards
From the material point of view
From a durable point of view, the best material should be stainless steel, especially as a surface material, the more bright it is. It has good strength, strong corrosion resistance and constant color. However, there are many kinds of stainless steel, which can be mainly divided into ferrite and austenite. Ferritic stainless steel has magnetic properties, commonly known as stainless steel. It takes a long time, and the environment is not good, it will rust. Only austenitic stainless steel will not rust. The identification method is very simple. It can be identified with a magnet.
Copper is one of the most widely used lock materials. It has good mechanical properties, good corrosion resistance and processing properties, and its color is beautiful. Especially for copper forged handles and other locks, the surface is flat, the density is good, and there is no air hole. Sand eyes. It is both strong and rust-proof. It can be used for plating various surface treatments such as 24K gold or gold, which is magnificent, noble and generous, adding a lot of color to people's home.
Zinc alloy materials have much lower strength and rust resistance, but have the advantage of being easy to make parts with complex patterns, especially for pressure casting. The locks of the more complicated patterns seen in the market are likely to be made of zinc alloy. Consumers should carefully identify them; steel has better strength and lower cost, but it is easy to rust. It is generally used as the internal structural material of locks. As an external decorative part; aluminum or aluminum alloy, ordinary aluminum alloy (except aerospace) is soft and light, and the material strength is lower, but it is easy to form.
