Welcome to Hemaokang Steel (Shandong) Co., Ltd., a professional steel pipe manufacturer located in Liaocheng, Shandong, China. We are proud to introduce our Hot Dipped Galvanized Steel Pipe BS1387 DN15-DN200, a high-quality product designed to meet the rigorous demands of global construction and plumbing projects. With our advanced production lines and strict quality control, we ensure every pipe delivers exceptional durability, corrosion resistance, and dimensional accuracy. Our factory, established in 2025, has quickly grown to serve clients across North America, South America, Europe, Southeast Asia, and beyond, with an annual export value of US$50-100 million.
This galvanized steel pipe is manufactured in accordance with the British Standard BS1387, ensuring compatibility and reliability in international markets. The pipe features a threaded coupling for easy installation, a Sch40 wall thickness for enhanced strength, and a 6-meter standard length (customizable upon request). The hot-dipped galvanized surface provides a uniform zinc coating that protects against rust and extends the service life of the pipe, making it ideal for both indoor and outdoor applications.
Key Features & Benefits
- Superior Corrosion Resistance: The hot-dipped galvanized coating offers robust protection against moisture, chemicals, and harsh weather conditions, reducing maintenance costs.
- High Strength & Durability: Manufactured from high-quality carbon steel (Q235/Q345), the pipe withstands high pressure and heavy loads, suitable for structural and fluid transport applications.
- Precision Threading: Each pipe end is threaded with precision to ensure a secure and leak-proof connection with the included coupling, saving installation time and labor.
- Compliance with BS1387: Our pipes meet the dimensional and mechanical requirements of BS1387, ensuring compatibility with existing systems and fittings.
- Versatile Applications: Ideal for water supply lines, plumbing systems, scaffolding, fencing, greenhouse structures, and general engineering purposes.
- Customizable Options: Available in various diameters (DN15 to DN200), lengths (up to 12m), and zinc coating weights (200-500 g/m²) to meet specific project requirements.
