Product Overview
As a professional Chinese supplier, we provide high-quality HDG Steel Welded Pipes, made via advanced ERW technology and hot-dip galvanizing. Our pipes feature excellent corrosion resistance, high structural strength and long service life, complying with international standards for global construction, plumbing and industrial projects.
Production & Quality Assurance
Our HDG welded pipes are made from high-quality Q195, Q235B, Q355B carbon steel strips. Advanced ERW welding ensures smooth, firm welds, while hot-dip galvanizing forms a uniform zinc coating (200–600g/m²) for anti-corrosion. Full-process quality control and ISO9001, ASTM A53 certifications guarantee stable batch quality.
