Welcome to Hemaokang Steel (Shandong) Co., Ltd. — a reliable manufacturer and exporter of ERW Galvanized Steel Pipe specifically designed for scaffolding construction framing. With our company established in 2025, we have rapidly grown into a global supplier with an annual export value of US$50 Million - US$100 Million, serving markets across North America, South America, Europe, Africa, Oceania, and Asia. Our ERW galvanized pipes are manufactured under strict ISO9001 quality management system, ensuring consistent performance, safety, and durability for your scaffolding projects. Whether you are building temporary structures, formwork supports, or permanent frameworks, our pipes offer the perfect balance of strength, corrosion resistance, and cost-effectiveness.
Product Description: Our ERW Galvanized Steel Pipe is produced using advanced electric resistance welding technology, followed by hot-dip galvanizing to provide a robust zinc coating that protects against rust and harsh environmental conditions. The pipes are specifically engineered for scaffolding construction framing, meeting the demanding requirements of load-bearing structures in the construction industry. With precise outer diameter, uniform wall thickness, and smooth surface finish, these pipes ensure easy assembly, secure connections, and long service life. Available in a wide range of sizes and lengths, they can be customized to fit your specific project needs.
Key Features and Technical Specifications
- Superior Corrosion Resistance: Hot-dip galvanized coating (minimum 60 microns) provides excellent protection against moisture, chemicals, and UV exposure, extending the lifespan of the pipe by 5–10 times compared to black steel pipes.
- High Strength-to-Weight Ratio: Made from high-quality Q235/Q345 steel, our pipes offer high tensile strength and yield strength, ensuring safe support for heavy loads in scaffolding structures.
- Precise Dimensions: ERW process ensures consistent wall thickness and roundness, reducing material waste and simplifying installation.
- Versatile Sizes: Outer diameter from 21.3mm to 273mm, wall thickness from 1.0mm to 12mm, and lengths up to 12 meters (custom cut available).
- Easy Welding and Fabrication: Excellent weldability allows for quick on-site modifications and connections.
- Eco-Friendly: Galvanized coating is fully recyclable, supporting sustainable construction practices.
