16Mn Galvanized Steel Pipe
16Mn Galvanized Steel Pipe (equivalent to Q345) is a high-strength low-alloy hot-dip galvanized steel pipe, available in seamless and ERW straight seam variants for heavy-duty applications. Its dense hot-dip zinc coating delivers excellent atmospheric corrosion and rust resistance with strong adhesion, while the 16Mn base boasts superior tensile strength, good low-temperature toughness and medium-high pressure bearing capacity. It features excellent weldability, formability and machinability, paired with precise dimensional tolerance and stable room-temperature mechanical properties. Durable and cost-effective for harsh working conditions, it’s a core anti-corrosion steel pipe for industrial heavy-duty structural and fluid transmission projects.
