Hemaokang Steel (Shandong) Co., Ltd. is a reliable manufacturer and supplier of high-quality galvanized steel pipes. Established in 2025, we have rapidly grown to an annual export value of US$50 Million – US$100 Million, serving customers across North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East. Our factory, located in Liaocheng, Shandong, China, employs 51–100 skilled professionals and holds ISO9001 certification, ensuring every product meets rigorous quality standards. The Galvanized Steel Pipe for Water Supply System (1 Inch Diameter, 2.5mm Wall Thickness, 6m Length) is crafted to deliver outstanding corrosion resistance, durability, and reliable performance in potable water and general plumbing applications.
This pipe is manufactured using pre-galvanized or hot-dip galvanized processes, providing a uniform zinc coating that protects against rust and extends service life. With a precise 1-inch nominal diameter (33.4mm outer diameter) and 2.5mm wall thickness, it offers excellent pressure-bearing capacity for residential, commercial, and industrial water supply systems. Each 6-meter length is carefully inspected and tested to ensure dimensional accuracy and leak-proof performance.
Key Features & Benefits
- Superior Corrosion Resistance: The hot-dip galvanized coating forms a metallurgical bond with the steel, preventing rust even in humid or corrosive environments. Ideal for underground or exposed water lines.
- Robust Wall Thickness (2.5mm): Provides enhanced strength and pressure rating, suitable for main water supply lines and high-flow applications.
- Standard 1 Inch Diameter: Compatible with most common fittings, valves, and connectors, simplifying installation and reducing system costs.
- 6-Meter Length: Reduces the number of joints needed, minimizing potential leak points and saving installation time.
- ISO9001 Certified Quality: Manufactured under strict quality management systems, ensuring consistent dimensions, smooth surfaces, and reliable performance.
- Wide Application Range: Works perfectly for potable water supply, fire sprinkler systems, irrigation, and structural support frameworks.
- Customizable End Finishes: Available with threaded ends, plain ends, or beveled ends per your project requirements.

Frequently Asked Questions
Q1: Is this pipe suitable for drinking water?
A: Yes, the galvanized steel pipe is manufactured with food-grade zinc coating and meets international standards for potable water supply. However, we recommend checking local regulations regarding galvanized pipes for drinking water, as some regions may require additional lining or certification.
Q2: What is the maximum working pressure for this 1-inch pipe with 2.5mm wall thickness?
A: The typical working pressure is up to 2.0 MPa (approximately 290 psi) for standard water supply applications. Actual pressure rating depends on factors like temperature, installation method, and end connections. Please consult our technical team for specific project requirements.
Q3: Can I get the pipe with threaded ends?
A: Yes, we offer threaded ends (NPT or BSP threads) as an option. Please specify your thread type preference when placing an order. Plain ends and beveled ends are also available.
Q4: How is the pipe packaged for export?
A: Pipes are bundled in steel straps, wrapped with waterproof plastic, and packed in seaworthy wooden crates or containers. Each bundle includes protective end caps to prevent damage during transit. Custom packaging is available upon request.
Q5: Do you provide samples before bulk order?
A: Yes, we offer free samples for evaluation (shipping cost is borne by the buyer). Samples can be any length up to 1 meter, with standard diameter and wall thickness. Contact our sales team to arrange.
Q6: What is the lead time for a 20-foot container order?
A: Typically, production takes 15–20 working days after receiving the deposit and confirming specifications. For urgent orders, we can expedite with a partial premium. Full container orders (20ft/40ft) are our specialty.
Q7: Does the pipe come with a warranty?
A: Yes, we provide a standard 12-month warranty against manufacturing defects, including issues with zinc coating adhesion, dimensional deviations, and material quality. Extended warranty terms can be negotiated for large projects.
Q8: Can I order pipes in different lengths or diameters?
A: Absolutely. We offer customization on diameter (from 1/2 inch to 12 inches), wall thickness, and length (up to 12 meters). Please contact us with your requirements for a tailored solution.
