ST35 Galvanized Steel Pipe
DIN ST35 Galvanized Steel Pipe is a premium German standard carbon steel pipe, mainly available in seamless type with a hot-dip zinc coating. Its high-purity carbon steel base ensures excellent medium-low pressure bearing capacity, while the dense zinc coating provides reliable atmospheric corrosion and rust resistance with strong adhesion. It features superior weldability, machinability and formability for on-site processing, paired with precise dimensional tolerance and stable room-temperature mechanical properties. Cost-effective and high-performance, it’s a mainstream anti-corrosion steel pipe for industrial medium-low pressure fluid transmission and precision structural applications.
