Towel rack quality depends on 2 points: 1, depending on the nature of the material, and 2, the surface processing technology.
The following are mainly introduced:
1. In comparison, the nature of stainless steel is not easy to rust (in fact, rust is an oxidation process). The characteristics ensure the most stability, so it is also the most commonly used. "Stainless steel" only needs to be directly polished or brushed. There is no change in surface material or coating, but depending on the grade, there are some differences in stability. The daily name of 304 is better than 201. The surface is polished, the material is good, and the processing technology can reach the mirror surface, but it is worse than copper plating.
2. "Copper" basically uses brass, and the surface is chrome-plated. If it is processed well, it can reach the mirror surface. With the natural price of copper, it will have a noble feeling. If it is not plated, the surface is very easy to produce patina. It cannot be used. Such a plating layer is much more reliable than a layer of "paint" on the surface of iron, but it also depends on the plating process, otherwise the surface will have a green patina if it is not used for several years. Because the price of "stainless steel" materials commonly used in sanitary ware products is much lower than that of copper materials, some manufacturers assume that the stainless steel materials are electroplated to be "copper" materials after they are electroplated. Well, although the cost of stainless steel plating is not cheap, it is generally cheaper.
3. Regarding "aluminum", the rigid strength of "pure aluminum" cannot meet the requirements for use and the surface is susceptible to oxidation. It is generally not used in rust-proof aluminum or hard aluminum, but it is unlikely The so-called aluminum alloy material is the same as that used in aerospace equipment. The surface of "aluminum alloy" material treated with oxygen oxidation is much more stable than that without surface treatment. There are also a variety of surface treatment processing results. Species: One kind of surface looks brighter, and the other kind looks matte. The former kind is thinner but harder, so it is not easy to scratch. The latter surface is like adding a coating film layer, although it is thick, but it is prone to scratches. The latter surface can be processed into a variety of colors, which is better in terms of aesthetics, which is also an advantage.
4, "Iron", because it is easy to rust, must be surface treated, divided into chromium plating or lacquering. In comparison, the plating layer above "Iron" is not as reliable as the plating layer above "Copper". With the painting process, the paint layer is also easy to scratch, peel and peel. However, it can have a variety of colors to make it more beautiful, and the paint layer is well treated and the life is not short. For example, automotive sheet metal paint layer, there are no major problems for more than ten years.
5. "Plastics", although they are inferior to the above-mentioned metal materials in terms of rigidity and strength, but engineering plastics are also applied to automobiles and other facts, so the reliability can basically meet the requirements for use. Plastics It can be processed into a variety of colors, structures, and the cheapest features. I think it is a good choice for users who are considering temporary use and not long-term use.
