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.
