Hemaokang Steel (Shandong) Co., Ltd. introduces our premium Thin Wall ERW Galvanized Steel Pipe in wall thicknesses of 0.8mm, 1.0mm, and 1.2mm, with a 20mm outer diameter, designed specifically for water line applications. As a newly established company backed by decades of industry expertise and an annual export value exceeding US$50 million, we combine rigorous quality control, advanced manufacturing, and cost-effective pricing to deliver pipes that meet the demands of global markets. Our galvanized steel pipes are engineered to provide corrosion resistance, durability, and ease of installation, ensuring a reliable water supply system for residential, commercial, and industrial projects.
Our pipes are manufactured using the Electric Resistance Welding (ERW) process, which ensures consistent wall thickness and smooth internal surfaces, minimizing pressure loss and sedimentation. The hot-dip galvanized coating provides a protective zinc layer that withstands harsh environments, making these pipes ideal for underground or above-ground water lines. With ISO9001 certification, you can trust the consistency and reliability of every batch we ship from the Port of Qingdao.

Q: Can these pipes be used for hot water?
A: Yes, the galvanized coating and ERW construction can handle hot water up to 60°C (140°F) continuously. For higher temperatures, consider using our specialized pipes. -
Q: Are the pipes threaded?
A: Standard pipes are plain-end. Threading is available upon request as a value-added service. -
Q: What is the minimum order quantity (MOQ)?
A: Our MOQ is typically 5 tons per specification, but we can accommodate smaller trial orders. Please consult our sales team. -
Q: Do you provide samples?
A: Yes, free samples (freight collect) are available for quality evaluation. Contact us to request a sample kit. -
