A hot galvanized square tube is a square tube made of a steel plate or a rolled steel strip, and a square tube formed in a hot galvanizing pool through a series of chemical reactions on the basis of this square tube.
The production process of hot-dip galvanized square tube is relatively simple, but the production efficiency is very high and the variety specifications are many, but the equipment and funds needed for this square tube are very few, and it is suitable for the production of small galvanized square tube manufacturers. However, the strength of the steel pipe is far below that of the seamless square tube. The cold galvanized square tube is used to make the square tube have the anticorrosive property on the square pipe used by the cold galvanizing principle. The different cold galvanizing coatings are mainly anticorrosion through electrochemical principle, so it is necessary to ensure the full contact between zinc powder and steel and produce electrode potential difference, so the surface treatment of steel is very important.
Hot galvanized square tubes are widely used, mainly using the curtain wall, construction, mechanical manufacturing, solar power support, steel structure engineering, especially in the curtain wall, building the most widely used.
