10kV-33kV Steel Utility Pole – Q355B Polygonal Single Pole for Distribution Lines
H2: Product Overview
Our 10kV–33kV Steel Utility Pole is a single-pole distribution solution made from Q355B high-strength steel. The polygonal design provides high wind resistance and structural rigidity. It is hot-dip galvanized to ISO 1461 for long-term corrosion protection.
As a China-based source factory, we support third-party inspection by SGS, BV, TÜV, or Intertek. Custom heights from 9m to 18m are available.
