2 Inch / 3 Inch / 4 Inch Galvanized Steel Pipe

2-inch, 3-inch, and 4-inch galvanized steel pipes are versatile, corrosion-resistant piping solutions widely used in plumbing, irrigation, fencing, and structural applications. Made from high-quality carbon steel with a hot-dip galvanized finish, these pipes provide excellent protection against rust and extend service life in harsh environments. Available in standard lengths of 6 meters (customizable), they comply with international standards like ASTM A53 or BS 1387, ensuring reliable performance for water, gas, or drainage systems. Their threaded ends simplify installation, while the zinc coating (200-600g/m²) ensures durability. Ideal for residential, commercial, and industrial projects, these pipes offer a cost-effective, long-lasting solution for various piping needs.
