Structural components of noise barrier and highway sign gantry for Tseung Kwan O - Lam Tin Tunnel project-Yuantai Derun Steel Pipe Manufacturing Group Project Case Episode 4
In 2023, Tianjin Yuantai Derun Steel Pipe Manufacturing Group Co., Ltd. received a very complex tunnel engineering project. After strict consideration and calculation by Yuantai engineers, the S355J0H standard of EN10210 has been adopted for structural rectangular steel pipes, with specific specifications of 300 * 500 * 20mm and a total of 1200 tons of steel pipes. So far, Yuantai Derun has provided structural steel pipe supply for over 6000 globally renowned construction projects. In a certain sense, choosing Yuantai Derun is equivalent to choosing peace of mind and quality.
