   Introduction
Benefits of galvanized pipe
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 tubing, galvanized steel round tubing corrodes much slower, extending the life of your tubing. 


In addition to this, galvanized pipe also provides:

  • Lower cost than stainless steel
  • Lowest long-term cost
  • Reliable performance
  • Excellent resistance to mechanical damage

Features:

  • Hold superior corrosion resistance strength
  • Can be installed in indoor as well as outdoor areas
  • Longer working life
  • Economical in operation
  • Uniform design
  • Available in various length, thickness and size
