Galvanized pipe is a kind of steel pipe coated with zinc layer, its main function is to improve the corrosion resistance of the steel pipe through the protection of zinc layer. Galvanized pipe is widely used in construction, water supply and drainage, HVAC, structural support and other fields, especially suitable for outdoor or humid environment.

Core selling point of galvanized pipe：

1.The surface of the galvanized pipe is covered with a layer of zinc, which can effectively prevent the pipe from oxidation and corrosion and extend the service life, especially for wet or corrosive environment (such as chemical plants, Marine climate, etc.). 2.The galvanized pipe has strong weather resistance and can resist the influence of harsh weather conditions on the pipeline, including strong ultraviolet irradiation and rain erosion. 3.The zinc layer not only protects against corrosion, but also increases the strength of the pipe, making it more resilient to pressure, shock and other mechanical effects.

Product Paramenters

Excellent corrosion resistance

The zinc layer on the surface of galvanized steel pipe can effectively prevent steel pipe rust, and has a longer service life in wet and corrosive environments.

High strength and durability

Galvanized steel pipe not only has the high strength and durability of steel, but also can effectively withstand high pressure and heavy load, suitable for engineering structure applications.

Excellent sealing

Especially for fluid transportation, galvanized steel pipe can provide stronger anti-leakage ability to ensure the stable operation of water supply, gas supply and other systems
