Hot Dip Galvanized Steel Pipe, Galvanized Pipe, GTC, galvanized threaded and coupling, GPE, galvanized plain end, Grooved steel pipe, round, square, rectangular, oval and other special section pipe
Hot-dip galvanizing (HDG), as referenced is the process of dipping fabricated steel into a kettle or vat of molten zinc. While the steel is in the kettle, the iron metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to the steel.
We can produce and supply to you various steel pipes according to international standard. Hot dip galvanized steel pipes are used in the following fields, steel structure, build structure, transportation of low pression liquid and gas etc. our products are exported to about 50 countries in the world, we get a lot of recognition from many customers since our good quality and service.
