Hardware Encyclopedia: How to buy hardware accessories

Hardware accessories can be used alone or as auxiliary appliances. For example, hardware tools, hardware parts, daily-use hardware, construction hardware, and security products. Most small hardware products are not final consumer goods. Rather, they are used as industrial manufacturing supporting products, semi-finished products, and tools used in the production process. Only a small part of daily-use hardware products (accessories) are consumer tools necessary for people's lives. Pay more attention to the following aspects when purchasing hardware accessories.

　　 choose hollow

　　 is also made of copper, which is also divided into hollow tubes and solid copper bars. It is recommended to buy hollow tubes. It's just used to hang towels. The solid pole is too expensive, so why bother.

　　 choose copper

　　 In terms of materials, hardware pendants include copper, stainless steel, aluminum, alloy, and plastic. It is recommended that you buy copper accessories. The reason is simple. Aluminum will oxidize, alloy will rust, plastic will be deformed, stainless steel is really difficult to rust, but if it is stainless steel with quality problems, there is no guarantee that it will not rust. Copper through a good electroplating process will not have these problems. Especially the base, moisture-proof and waterproof is better than copper.

　　 choose smooth

　　The most difficult thing to choose a pendant is to look at the coating, because for the average consumer, the rough look is basically the same. Coating treatment is very important for copper pendants, and it is related to product service life, smoothness and wear resistance. At the same time, the coating treatment is also the biggest cost in the process of making copper pendants except for the copper blanks. The specific electroplating process is not much to say.

　　 How to judge the quality of a copper key coating? Good coatings are black and shiny and have a moisturizing feel, while inferior coatings are dull. A good coating is very flat, while a poor-quality coating will find wavy undulations on the surface if you look closely. Those with depressions on the surface must be inferior products. A good coating is more wear-resistant, and the samples displayed by the merchants in the store must be wiped every day. The surface of the good product is basically invisible, while the surface of the inferior product will have a dense number of scratches.
