Huanji Expressway (Huanren to Ji 'an) is the terminating section of Benji Expressway (Benxi to Ji 'an), which connects with Jishuang Expressway, with a construction length of 57.807 km. After the completion of the Jian-Huanren Expressway project, it will further shorten the time distance between the southeast of Jilin Province and the central and eastern Liaoning Province, connect the tourist attractions along the Yalu River, which is of great significance to the level of local transportation infrastructure, highway traffic capacity, the improvement of people's livelihood and the development of tourism industry, and better create a window for Jilin Province to open to the south. Integration into the Bohai Rim economic Circle has provided important transportation support and helped the comprehensive revitalization of Northeast China in the new era.

Benheng Expressway (Benxi to Huanren) project is located in Liaoning Province, the main line length of 176.105 kilometers, is the most complex geological in Liaoning Province, the most difficult to build, bridge and tunnel ratio of 35% of the mountain highway, halfway across iron, bridge and river quite. The project is expected to be completed in 2026. After the completion of the project, it will greatly reduce the distance between Shenyang and Benxi and Huanren, and form a rapid traffic network with a 3-hour traffic radius at the core of Shenyang.

Since the official construction of this set of high-speed, Jilin Xinda Steel has supplied 14-20 I-beams with full specifications, covering the construction of roadbeds, Bridges, tunnels and other high-speed lines. At the critical moment of vigorously promoting the comprehensive economic revitalization of the two Northeast provinces, Jilin Xinda Steel has contributed steel strength to the economic development bridge connecting the eastern alpine region.

Most of the high-speed line in this set is located in the northern cold region, which needs high-quality I-steel products with cold resistance, strong bending resistance, good product toughness and easy welding, etc. Jilin Xinda Iron and Steel has formulated strict rolling standards according to the product use, strictly implements the process system of heating temperature, rolling speed and cooling temperature, and optimized various process control parameters. Strictly control the whole production process to ensure that products meet customer requirements.

In order to ensure product quality "zero error", Jilin Xinda Iron and Steel strictly controls the quality of raw materials entering the factory and products leaving the factory during the production process, and constantly improves the product testing ability and level of inspection personnel. In terms of product process research and development, the successful development of a sweeping device for purging impurities, a rust removal device for finished steel products, and a roughing mill with the function of removing water on the surface of steel sheets has had a positive impact on the solution of the surface rust bottleneck problem of the entire hot-rolled H-beam, I-beam and multi-variety steel rolling industry, and found a low-cost solution to steel storage. The new process method of surface rust in transportation engineering meets the demand of customers for high-quality steel.

Over the years, Jilin Xinda Iron and Steel has always followed the customer-oriented production and management philosophy, and used high-quality products to help the construction of key projects such as national rail transit and expressways. It has been widely used in projects such as Greater Khinganling National Petroleum Reserve, Shenzhen-Bai high-speed Railway, Changchun Shelter Hospital, etc., which has been praised by customers and established a long-term good partnership.

The company has repeatedly won the national steel industry quality leading brand, national quality inspection stable qualified products, national quality trustworthy products, national steel industry quality leading enterprises, national quality integrity demonstration enterprises, national quality integrity demonstration enterprises, national quality integrity benchmarking typical enterprises, Liaoyuan City industrial quality development excellent enterprises, construction steel quality brand demonstration base, Northeast Regional steel circulation brand certificate and title.

Hold fingers into fists, and work together to reach far. Jilin Xinda Iron and Steel Co., Ltd. with the accumulated struggle, in exchange for the rapid development and progress; With the determination and perseverance of dripping water, in exchange for the innovative breakthrough of sand into a tower. In the future, we will tap the potential to strengthen the foundation, improve the quality and upgrade, accelerate the promotion of high-level core technology self-reliance, forge quality reliable, reputation guaranteed, market popularity, and strong competitiveness of the fine steel, with the strength to confirm the quality of Xinda, help more big country projects to rise!
