Galvanized guardrail in life is very common for our lives and the environment have made a great contribution. Then the hot-dip galvanizing understand so much knowledge of the cold galvanizing you have to know how much of it? Here together for you to explain it: the popular talk cold galvanized also called electro-galvanized, its principle is based on electrolysis equipment will pipe through degreasing, pickling, into the composition of zinc salt solution and connected electrolysis negative electrode device, opposite the tube member disposed zinc plate, after connecting the positive electrode of the electrolytic device powered by current from the positive electrode to the negative electrode of the directional movement will be deposited on the zinc layer pipe, the pipe is first cold-plating processing galvanized . Since the early development of hot-dip galvanizing production, up to the present has been widespread concern, however, the hot-dip galvanizing industry is accompanied by the rapid development of the last three decades of cold-rolled strip and get a large-scale development. Production processes include: original board ready → → → hot-dip coating after treatment → finished product inspection before plating treatment. Another way is completely different from the cold galvanized hot dip galvanized, hot dip galvanized hot dip galvanized fence is to the best interpretation of this technology.
