Hook scale market details - tak kong hook scale Hook scale is used in the external environment of the equipment, this equipment often need wind blowing rain, so for the shell manufacturing process and material requirements are very strict, if not up to the requirements of the hook scale, then such a shell will be eliminated, and is easy to cause a variety of rust phenomenon. Then what kind of material is better for the shell of hook scale?   At present, the market sales hook scale, the use of the shell of aluminum alloy, channel steel, stainless steel three kinds, the three types of material, actually have its good place, the advantage is very obvious. But because the hook scale shell is used in the external environment, many factors can not be ruled out, so the three materials are required to resist the impact of some external strength, not only electrical and thermal conductivity is good, but also need to do not easily deformation. From these requirements can be analyzed, the effect of aluminum alloy is the best, because although channel steel quality is also very good, conductivity and thermal conductivity is good, but do not because the channel is generally very hard material, used as a beam, so the conductive it is must be strictly forbidden, so, channel steel hook scale is commonly used in indoor, but cannot be used in outdoor. In addition is stainless steel, stainless steel stability is obvious to all, but stainless steel relative to aluminum alloy, to be thinner, that is to say, use stainless steel to make hook scale shell, easy to appear phenomenon is deformation, so it is very inappropriate to use in the field of hook scale. Such calculation down words, only the most suitable use of aluminum alloy in the hook balance of the shell. Because, in the aluminum alloy, increased the alloy element, and the existence of the alloy element, can ensure that in the use of the phenomenon, will not appear deformation, more stable. And the strength is higher, because it adds high strength aluminum, and aluminum stability and strength is relatively high, so that, even in the face of a strong impact, it is difficult to make this hook scale shell change. In addition, aluminum alloy has a great advantage is the density, the density is not easy to be eroded by external forces. At this point, the advantage of aluminum alloy is very obvious, so aluminum alloy will be used in the hook scale field, and is used in the most important shell above, to protect the hook scale.
