Description
What is the 10# Galvanized Steel Pipe?
10# Galvanized Steel Pipe is a type of carbon steel tubing coated with a layer of zinc to prevent corrosion and extend service life. Made from low-carbon 10# steel, it offers excellent plasticity, weldability, and moderate strength, making it a preferred choice in various industrial and civil engineering applications.
Available in:
-
Round Pipe (DN15–DN200)
-
Square Tube (15×15–600×600 mm)
-
Rectangular Tube (10×20–500×600 mm)
Coating types include hot-dip galvanizing for long-term outdoor use and electro-galvanizing (cold galvanizing) for economic indoor applications.
