What Are The Specifications And Models Of Galvanized Square Pipe

Zinc square tube is a section steel tube with hot-rolled or cold-rolled galvanized steel plate or galvanized plate as the blank shape and after cold bending, welded square hollow square section shape and size of high-frequency; or cold hollow steel, galvanized in advance. A kind of

Classification of galvanized square pipe:
Galvanized square pipe is divided into hot galvanized square pipe and cold galvanized square pipe from the production process. This is precisely because these two zinc plating methods are different, which makes them have many different physical and chemical properties. Generally speaking, they are quite different in strength, toughness and mechanical properties. A kind of
Hot dip galvanized square pipe:
The hot-dip galvanized square tube is a square tube welded by steel plate or steel strip. On the basis of the square tube, the square tube is placed in the hot-dip galvanized pool and formed through a series of chemical reactions. The technology of hot-dip galvanized square pipe is relatively simple, with high production efficiency, many varieties and specifications. The square tube needs little equipment and capital, which is suitable for small galvanized square tube manufacturers. However, the strength of steel pipe is far lower than that of seamless steel pipe. A kind of
Cold galvanized square pipe:
Cold galvanizing square pipe is to use the principle of cold galvanizing of square pipe to prevent the square pipe from corrosion. The hot-dip galvanizing of different zinc coating is mainly protected by the electrochemical principle. Therefore, it is necessary to ensure the full contact between the zinc powder and the steel to produce the electrode potential difference, so it is very important to carry out the surface treatment of the steel.
