At present, what are the domestic enterprises specializing in producing corrugated steel webs?

Relying on China Top 500 Private Enterprises Group, Zhejiang ZhongTunnel Bridge is committed to the research and development and advocacy of corrugated steel plate and special steel structure technology, and is engaged in corrugated steel plate composite box girder, corrugated I-beam and I-beam, corrugated steel plate structural deck system, corrugated steel plate composite box girder, corrugated steel plate hollow steel pipe pile, corrugated steel plate tunnel and culvert, corrugated steel plate building shear wall, corrugated steel plate long-span roof, special steel pipe composite structure, corrugated and special steel concrete composite structure, etc. The company's headquarters and manufacturing base are located in Xiaoshan, the capital of steel structure in China, and an innovative R&D base of steel-concrete composite structure in China has been established. The first phase covers an area of 30,000 ㎡, with a building area of18,000 ㎡, with an annual output of 65,438+10,000 tons of corrugated steel plates and special steel structures. With all independent intellectual property rights and world-class 400-meter corrugated steel plate production line and testing equipment, it has become the first innovative scientific and technological enterprise in China to produce large corrugated steel plates with a thickness of 30 mm. ..

China Tunnel Bridge, together with Highway Research Institute of Ministry of Communications, Tsinghua University, Southeast University and well-known domestic research and design institutes, has developed a number of practical, advanced and economical corrugated steel plate composite structures. In the construction of several key projects with corrugated steel webs, it has created many firsts in the history of similar bridge construction in China: the single-span 1.20 m corrugated steel web composite structure was built for the first time in Juancheng Yellow River Highway Bridge in Shandong Province, which is the longest PC composite structure with corrugated steel webs in the world at present, and the overall structure with 1.460 m without expansion joints ranks first in the world; He undertook the corrugated steel web project of Weihe Bridge on Daguang Expressway in Henan Province, which is the first corrugated steel web composite structure applied to high-grade highways in China. It has undertaken Taohuayu Yellow River Bridge on Wuxi Expressway in Henan Province, and the largest single-span135m corrugated steel web composite beam bridge under construction and completion in China. It is the first cable-stayed bridge with corrugated steel webs without backstays in China-Qinshui Road Bridge in Xinmi, Henan Province, with a width of 50 meters, which is also the widest deck of this kind of structure. At present, the corrugated steel plate composite structure technology has been widely used in Japan, South Korea, Germany, France, Venezuela, Taiwan Province Province of China and other countries and regions, and more than 200 large-scale projects such as bridges and tunnels have been built.

China Tunnel Bridge will always adhere to the enterprise tenet of "independent innovation, energy saving and material reduction, honest management and giving back to the society" and devote itself to the development of new bridges, tunnels and major structural projects in China. We are willing to join hands with friends from all walks of life for a win-win situation and contribute to China becoming a world engineering power.
