Grade:NGHDG-10
Product:Excellent corrosion resistance Zn(0) Hot DIP Galvanized Steel Pipe
Galvanized pipe, also known as galvanized steel pipe, divided into hot dip galvanized and electric galvanized two, hot dip galvanized galvanized layer thick, with uniform coating, strong adhesion, long service life and other advantages. Electric galvanized cost is low, the surface is not very smooth, its own corrosion resistance is much worse than hot dip galvanized pipe.

Advantages
a. Because the pipes are galvanized, it is protected from rust and corrosion. Steel rusts after interacting with water or moisture in the air over time. By adding a coating of zinc to the pipes, galvanized steel round pipe corrodes much slower, extending the life of the pipes
b. Lower cost than stainless steel
c. Lowest long-term cost
d. Reliable performance
e. Excellent resistance to mechanical damage
