The cold galvanized square tube on the side of the tube is used in principle to the use of cold galvanized square pipes with anti-corrosion properties. Different cold galvanizing paint primarily through electrochemical principles to be preserved, we must ensure full contact with zinc and galvanized steel pipe, generating electrode potential difference seamless square tube manufacturers, so it is important steel surface treatment and galvanizing . Galvanized square tube: in the use of steel sheet or strip coiled square tube welded after forming and will be the basis of this square tube galvanized square tubes in the pool and then through a series of chemical reactions forming a square tube. Galvanized square tube production process is relatively simple galvanized pipe, and the production efficiency is very high, also many different specifications, equipment and funds needed for this little square tube, galvanized square tube manufacturers for small production . But the strength is the strength of this is far below the seamless steel pipe square tube.
