What is the difference between cold rolled galvanized and hot dipped galvanized steel?
Wiki User
∙ 11y ago
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.

What is the Difference between tempered glass and safety glass?
Tempered glass is a type of safety glass. Standard glass is rolled through a special kiln at around 700 degrees c. for between 100 and 400 seconds depending on the type and thickness of the glass. Some glass typed may take longer. This process makes the pane of glass very difficult to break under normal circumstances. If the pane does break it will shatter into thousands of tiny pieces instead of large shards, reducing the risk of serious cuts.

What are the advantages of hot rolling?
Hot rolled steel is steel that is rolled out when it is hot. We often see clips of sheets, slabs or bars of red-hot steel being rolled to give them a required shape. As steel becomes hotter, it can behave in a more plastic way and can be more easily sized and shaped by the rollers. We see flat sheets or long bars and rods of steel come out of the rollers. Railroad track is hot rolled to make it into the shape we know. We know that steel that is hot rolled will be more flexible than cold rolled steel because the hot-rolled steel has larger crystal structure. Cold rolling creates smaller crystals in the matrix, and that makes cold-rolled steel stronger and harder, but less flexible. If the cold rolling process is not carefully monitored, the steel can become brittle and can be hard to work with.
