What is the difference between cold rolled galvanized and hot dipped galvanized steel?
Hot-dip galvanized pipe is made by reacting the iron substrate with molten metal to form an alloy layer, thus combining the substrate with the coating. Hot-dip galvanizing requires pickling of the steel pipe to remove iron oxide from the surface of the pipe. After pickling, it is washed in an aqueous solution of zinc chloride or ammonium chloride or a mixture of ammonium chloride and zinc chloride and then sent to a hot dip galvanizing bath. Hot dip galvanizing has the advantages of strong adhesion, uniform coating and long service life. Cold galvanizing is what we call electro-galvanizing. The amount of galvanization is very small, and the corrosion resistance of cold galvanized pipe itself is very different from that of hot galvanized pipe, so many construction projects do not use cold galvanized pipe. At present, the Ministry of Construction has officially stated that technically backward cold galvanized pipes need to be eliminated, and cold galvanized pipes will not be allowed to be used as water and gas pipes in the future. Shanghai Changzheng's cold rolled steel sheets are of superior quality and are the choice of most people. Buy steel plates from Shanghai Changzheng.

Why does bleach rust a steel nail?
Bleach works by oxidizing the stain it's treating. "Oxidize" means it removes an electron from it, so the bleach removes an electron from the stain. Rust is also formed by oxidation, the removal of an electron from a metal. So if bleach can remove an electron from a laundry stain, it can also remove one from a metal.
