Product Introduction

Pre-galvanized steel pipe is a square or rectangular hollow steel tube made from galvanized steel belt, processed using cold bending forming and high-frequency welding. Its core feature is the use of pre-galvanized steel strip direct tube production, which results in a uniform zinc layer of 20-50μm, offering both corrosion protection and production efficiency. This process reduces costs by 15%-25% compared to hot-dip galvanized pipes, making it ideal for lightweight and low-corrosion environments.

Application Scenarios

• Construction: Used in framework assemblies, temporary access structures, safety railings, and perimeter barriers.
• Water and Gas Pipelines: Employed in potable water networks, crop irrigation systems, and fuel gas distribution systems.
• Agricultural and Irrigation Systems: Ideal for irrigation and drainage applications in agricultural fields.
• Electrical Conduits: Used to protect electrical wiring, particularly in weatherproof installations.
• Telecommunications: Used for housing fiber-optic cables and reinforcing transmission towers.

Production Process

The pre-galvanized steel pipe is produced using galvanized steel strips as raw material, following a process that includes shearing, rolling, welding, zinc coating, passivation, cutting, and packaging. Yuantai Derun’s design incorporates aluminum and magnesium alloys for enhanced corrosion resistance and aesthetic qualities.

Product Advantages

• Superior Corrosion Resistance: Uniform zinc coating ensures effective corrosion protection and durability.
• Cost Efficiency: No secondary galvanizing process, reducing costs compared to hot-dip galvanized pipes.
• Reduced Maintenance: Long-lasting protective layer reduces the need for frequent maintenance.
• Environmental Adaptability: Suitable for a wide range of applications, outperforming non-metallic materials like PVC.
• Eco-Friendly Production: Fewer toxic byproducts are generated during the pre-galvanizing process.
