All products of the company are strictly supervised and regularly inspected by the scientific research station of the General Equipment Department, ensuring that each product meets strict quality standards. We have successfully passed the ISO9001:2015 international quality system certification and have been awarded the honorary title of Quality System Management Demonstration Unit by China Quality Observation Station. Technological innovation is our eternal goal. We have successfully applied to the China National Intellectual Property Administration for the invention patent of the production process of fabricated highway steel bridge and the utility model patent of its products. Our core product, prefabricated highway steel bridges, also known as Bailey bridges or Bailey bridges, adopts the standards of the "Technical Specification for Construction of Highway Bridges and Culverts" (JTJ041-2008) issued by the Ministry of Transport for processing and production. Its application fields cover multiple engineering construction fields such as national defense readiness, flood control and emergency response, transportation, water conservancy, railways, and bridges. To meet the needs of the international market, the steel products we export have undergone SGS testing to ensure full compliance with American and European standards. Moreover, the main welds have undergone ultrasonic testing to ensure full compliance with welding standards. In addition, the Bailey bridges produced by us have been tested by professional testing agencies and fully comply with design standards. We have to emphasize a major technological breakthrough in modern engineering practice - the introduction of automatic welding robot technology. In order to continuously optimize the production process and ensure the accuracy and quality of products, we have conducted in-depth research on the welding process and selected to introduce this advanced technology. This automatic welding robot not only ensures accurate connection of each part, but also can complete a large amount of welding work in a short time, greatly improving production quality and efficiency. In years of industry practice, the company has successfully cooperated with multiple well-known enterprises and units and achieved significant results. The cooperation cases include Maldives Steel Bridge with China Communications Construction Corporation Second Highway Engineering Co., Ltd., Shenzhen Zhongshan Expressway of China Communications Construction Corporation Second Highway Engineering Co., Ltd., China Construction Engineering Corporation Hangzhou Expo Center, the new Sichuan Tibet Railway of China Railway 11th Bureau, and the Lalin Railway Trestle Project jointly constructed by China Railway 12th Bureau in Xizang. These successful cooperation cases fully demonstrate our company's professional strength and profound experience in the field of bridge manufacturing and engineering construction, while also consolidating our position in the industry.
