August 11 at 6:00 am, the company's Chief Engineer Douglas Young and his party drove to Taizhou Rope Net enterprises in Jiangsu Province for investigation. When passing the flexible Guardrail Jia-shao High-speed test section, Yang made a brief inspection on the flexible guardrail test section which has been running for many years. Arriving at the rope net enterprise at 10:30, Yang had a brief exchange with the person in charge of the enterprise, and then went into the workshop with the technical personnel to understand the rope net manufacturing technology and discuss relevant technical issues. Yang and his party then visited another rope net enterprise and had a technical exchange with the person in charge of the enterprise. The purpose of this research is to carry out the early research results of "research on development and application of new materials for traffic safety protection" , a cooperative project between our company and Zhejiang Jiaotong Group. In the previous work, we have had many exchanges with Xiaoshan east of Jinqu expressway in Hangzhou and made a preliminary plan for laying the experimental section of the protective net. The purpose of this inspection is to finalize the experimental section plan.
