Gi Galvanized Square And Rectangular Steel Pipe For Build Agricultural Greenhouse
Galvanized pipe, also known as galvanized steel pipe, is divided into hot-dip galvanizing and electro galvanizing. The hot-dip galvanizing layer is thick and has the advantages of uniform coating, strong adhesion and long service life. The cost of electro galvanizing is low, the surface is not very smooth, and its corrosion resistance is much worse than that of hot-dip galvanized pipe.
Galvanized steel is a carbon steel that has been coated with zinc. The most common method of zinc coating is the hot-dip process. The hot-dip process consists of submerging the carbon steel into a molten zinc bath (approximately 680 degrees Fahrenheit).
