[Haichuan Overseas Engineering] Telecommunication tower completed for gas treatment project in Soyo, Angola
Thread Content
Completion of the telecommunications tower for the Soyo gas treatment project in Angola Recently, the installation of the main structure of the telecommunications tower for the Soyo gas treatment project in Angola, undertaken by Sanhua Construction, was successfully completed. The tower is a three-legged steel pipe structure standing 90 meters tall; it features a triangular stabilization design using hot-dip galvanized steel pipes, which grants it excellent wind resistance capability, allowing it to withstand strong winds of 150 to 200 kilometers per hour. Its successful completion not only fills the gap in high-end communication infrastructure in the Suoyao area, but it also represents another landmark achievement by Sanhua Jian in actively implementing the Belt and Road Initiative and deepening capacity cooperation between China and Angola.
