Galvanized Round Pipe

With these advantages, galvanized round pipes are widely used in outdoor steel structure construction, providing solid support for buildings; in pipeline transportation, ensuring safe and efficient fluid transmission; in fencing and railings, combining aesthetics and protection; and in agricultural greenhouses, creating a stable environment for crop growth.

Galvanized round pipes are hollow, round steel pipes made by hot-dip galvanizing ordinary carbon steel round pipes. This treatment gives them superior corrosion resistance. The zinc layer formed by the hot-dip galvanizing process reaches a thickness of 80-120 g/m², uniformly adhering to the steel pipe surface. It can withstand salt spray corrosion for over 1000 hours and has a service life of over 30 years. Compared to ordinary black pipes, its corrosion resistance life is extended by 5-10 times, significantly reducing maintenance costs for outdoor projects.

Besides corrosion resistance, galvanized round pipes also excel in strength and economy. The carbon steel base material has a strength between 235-345 MPa, and the circular cross-section design ensures more even stress distribution, saving 20%-30% of material compared to other shapes of steel. Moreover, its bright, shiny zinc layer is suitable for exposed installation, eliminating the need for secondary coating, thus saving costs and improving construction efficiency. In terms of installation, it is easy to weld, can be threaded, and is convenient to cut, making construction very convenient.

Shunchen Industry boasts extensive experience in galvanized round pipe production, with over 20 years of accumulated production technology, a 12-year track record of zero breaches of contract, and zero annual quality incidents. Utilizing high-frequency welding combined with a fully automated hot-dip galvanizing production line ensures strong welds and a uniform zinc layer. The production process involves three passivation treatments to enhance the product's resistance to alkali corrosion. Each finished product undergoes drying, inspection, and fine finishing before packaging and shipping.

(FAQ)

Q1: What's the difference between galvanized round pipes and ordinary black pipes?

A: Galvanized round pipes have a hot-dip galvanized coating, providing 5-10 times longer corrosion resistance and are suitable for outdoor use; black pipes are only for short-term indoor use.

Q2: How to choose the zinc coating thickness?

A: For coastal/humid environments, choose 120g/m² or higher; generally, 80g/m² is sufficient for outdoor use. We will provide free recommendations based on the project.

Q3: Do you support internal plating or special zinc coatings?

A: Fully supported. Internal and external plating are possible for transporting drinking water; customization is welcome.

Q4: What documents are required for export?

A: A complete set of documents including material certificate, zinc coating report, certificate of origin, and SGS testing results.
