Supply high quality galvanized pipes
Galvanized pipe is a steel pipe that has undergone a special anti-corrosion treatment. A zinc coating is applied to the steel pipe surface to effectively prevent oxidation and corrosion. This treatment significantly extends the service life of the steel pipe, enabling it to maintain its structural integrity in a variety of harsh environments. Galvanized pipe is primarily divided into two types: hot-dip galvanizing and electro-galvanizing. Hot-dip galvanizing, achieved by immersing the steel pipe in molten zinc, creates a thick zinc layer, offering enhanced corrosion resistance. Electro-galvanizing, on the other hand, uses electrolytic deposition to form a thinner but more uniform zinc layer, resulting in a smoother and more aesthetically pleasing surface.
Application of Galvanized Pipe
Galvanized steel pipes are widely utilized in numerous industries due to their exceptional corrosion resistance and durability. These pipes are commonly employed in water supply systems for residential, commercial, and industrial buildings, as well as in outdoor plumbing applications where exposure to moisture demands reliable protection against rust. They serve extensively in structural frameworks, including handrails, fences, and scaffolding, thanks to their high strength-to-weight ratio and longevity. Additionally, galvanized pipes are integral to agricultural irrigation systems, fire sprinkler networks, and oil and gas transportation lines, where their robust zinc coating provides critical defense against harsh environmental conditions and chemical corrosion.
Our galvanized steel pipes are manufactured using advanced hot-dip galvanizing and electro-galvanizing processes, providing superior corrosion resistance for various industrial applications. Available in thicknesses ranging from 0.2mm to 5.0mm and widths from 600mm to 1500mm, these pipes meet diverse project requirements with customizable lengths up to 6000mm.
All our galvanized pipes comply with international standards including ASTM, ASME, GB, DIN, JIS, ISO, EN, and BS, ensuring consistent quality and performance worldwide. We source our materials from reputable steel manufacturers such as Baosteel, Shagang, Angang, Shandong Steel, and Shougang, guaranteeing reliable products for your construction, plumbing, and structural applications.

Hot-dip Galvanized Pipe
Hot-dip galvanized pipe is a type of steel pipe that has been coated with a protective layer of zinc through a hot-dip galvanizing process. This process involves immersing the steel pipe in a bath of molten zinc at temperatures typically around 450°C (842°F), which creates a metallurgical bond between the zinc and the steel substrate.
The resulting coating provides excellent corrosion resistance, making hot-dip galvanized pipes ideal for various applications including outdoor structures, water supply systems, fencing, and construction projects. The zinc coating acts as a sacrificial barrier, protecting the underlying steel from rust and environmental elements.
Electro-galvanized pipe
Electro-galvanized pipe is a steel pipe that is coated with a thin layer of zinc through an electroplating process. The zinc ions are deposited onto the surface of the steel pipe using electric current, forming a more uniform and more precisely controlled coating.
The electro-galvanizing process results in a smooth, consistent finish with excellent aesthetic appeal, making these pipes particularly suitable for applications where appearance matters. The zinc coating provides good corrosion resistance, though generally less robust than hot-dip galvanized pipes in harsh environments.
