Galvanized hollow steel pipe is a square or rectangular-section steel pipe that has undergone hot-dip galvanizing treatment. It has a hollow structure inside. While maintaining sufficient strength, it improves the efficiency of transportation and installation. The hot-dip galvanizing process involves immersing the steel pipe into molten zinc liquid, forming a uniform and dense zinc layer on its surface, thus enhancing the corrosion resistance of the steel pipe.

Hot dip Galv. Tube production technology and applicationGalvanized steel pipe is the carbon steel pipe that are coated with a protective layer of zinc. The zinc layer served as a sacrificial layer, it will get rust before the carbon steel under neath it. Galvanized steel tubeS include Two types: hot

The galvanized pipes are widely used in oil transportation and construction，such as steel structure, buildings, guard rails, fences, metal furnitures and etc. Due to its zinc coated surface,the galvanized pipes are anti-corrosion. Here are 2 types of galvanizing: hot dip galvanizing and pre-galvanizing. Based on the enviroment of the product needs, you can choose your fittable product.
