Both   hot-dip galvanizing and cold-galvanizing   are zinc processing techniques. Hot-dip galvanizing requires melting zinc, while cold-galvanizing adopts an electrolytic method. They are very different during production, but they are similar in the performance of the finished product. So how to distinguish hot-dip galvanizing and cold-galvanizing? What are the differences between them in which aspects? Let’s understand together! The differences between hot-dip galvanizing and cold-galvanizing can be distinguished from several aspects. First, the differences between hot-dip galvanizing and cold-galvanizing. Different thicknesses. The zinc layer of hot-dip galvanizing is relatively thick itself, generally with a thickness of more than 10 um, so it has good anti-corrosion ability. Although the surface is bright, it is slightly rough and zinc flowers may appear. While the zinc layer of electro-galvanizing is very thin, only about 3-5 um in thickness. Although the surface is smoot...
