China wholesale Astm A500 Square Steel Tube - Manufacturer of galvanized square steel pipe for guardrail pipe – Zheyi Detail:

 Galvanized square pipe from the production process is divided into hot dip galvanized square pipe and cold galvanized square pipe. It is because of the different processing of these two galvanized square tubes that they have many different physical and chemical properties. In general, there are many differences in strength, toughness and mechanical properties.

Hot dip galvanized square pipe
Hot-dip galvanized square tube is a square tube made of steel plate or steel belt crimped and welded. On the basis of this square tube, the square tube is placed in the hot-dip galvanized pool and formed after a series of chemical reactions. The production process of hot-dip galvanized square pipe is relatively simple, and the production efficiency is very high, and the varieties and specifications are also many. This square pipe requires little equipment and capital, which is suitable for the production of small galvanized square pipe manufacturers. But from the strength of the steel tube strength is far lower than seamless square tube.

Cold galvanized square pipe
Cold galvanized square pipe is in the use of the principle of cold galvanized square pipe to have corrosion resistance. Different from hot dip galvanized cold galvanized coating is mainly anticorrosive through the principle of electrochemistry, so it is necessary to ensure sufficient contact between zinc powder and steel, resulting in electrode potential difference, so the steel surface treatment is very important.
