Not long ago, Changtai Yangtze River Bridge, the world's largest span cable-stayed bridge and the largest span public-railway dual-use steel truss girder arch bridge in which Nanshan Steel participated in supplying steel, was opened to traffic.
Changtai Yangtze River Bridge is located between Taizhou Yangtze River Bridge and Jiangyin Yangtze River Bridge, connecting Taixing City of Taizhou in the north and Xinbei District of Changzhou in the south, shortening the travel time between the two places from 80 minutes to about 20 minutes. This set of highway, intercity railroad, primary highway "three in one" river crossing, from design to construction to achieve a number of world firsts, the world's most.
In the past, the road surface of the railroad steel bridge is mostly composed of concrete and single material steel plate, when it rains and winds, the coarse gravel or gravel laid on the railroad bridge surface is easy to store water, forming crevice corrosion, affecting the service life of the railroad steel bridge. In order to solve this problem, NSC innovatively launched "stainless steel + carbon steel" "bridge steel + stainless steel" and other composite plates.
According to the South Steel new materials technology research experts, composite plate is several different characteristics of the steel, according to the scene application requirements using a certain way to make a steel plate, in the pipeline, bridge, ships and other fields. This kind of composite plate products both base material (carbon steel) toughness, but also has the cover material (stainless steel) excellent corrosion resistance, and cost reduction, is a set of functional, structural and economic in one of the low-carbon green high-performance composite materials.
Nanshan Steel will be the high-grade composite plate used in the construction of Changtai Yangtze River Bridge, the composite plate used to meet the high strength, high toughness, good weldability and other comprehensive performance, which is the first to realize the batch application of high-grade bridge composite plate in China, Nanshan Steel is the largest supplier of high-grade bridge composite plate in China for this project.
In developing this composite plate applied to the bridge, Nangang innovated the use of vacuum rolling composite technology. This technology won the first prize of Metallurgical Science and Technology Award 2025 from China Iron and Steel Industry Association and China Society for Metals.
Nanshan Iron & Steel, with its "steel backbone" across the Yangtze River, has once again set a new world record for manufacturing in a large country. Similarly, another large enterprise from the new area - Sumida Energy Holdings Limited's Huilun Solar, its photovoltaic products across the ocean, highlighting the hardcore power of domestic science and innovation.
Recently, the Tianlongxing series of PV modules produced by Phono Solar won the Building Technology Certification issued by the German Institute of Building Technology (DIBt), and is one of the first PV brands in China to be awarded this honor, which marks an important breakthrough for Sumida Phono in terms of safety, environmental sustainability, and technical performance, and is a vivid portrayal of the products of the new zone enterprises going overseas.
DIBt (German Institute for Building Technology) is the German federal building certification authority responsible for compliance assessment of building materials, structural systems, energy components, etc. DIBt focuses on the compliance of photovoltaic modules as "building components", emphasizing their overall compliance with structural mechanics, fire resistance, and material stability.
Such stringent certification standards are a "cross-border challenge" for Chinese manufacturers: components are no longer just electrical products, but part of the building body, and their design concepts, performance targets, and compliance paths must be switched from "power plant logic" to "building logic". The design concept, performance target and compliance path must be switched from "power plant logic" to "building logic".
Tianlongxing series PV modules utilize advanced technology and production process, with high photoelectric conversion efficiency and excellent power generation performance. Moreover, the modules are highly adaptable and widely used, and can maintain good power generation performance under a variety of conditions such as BIPV, vertical installation, snow, high humidity, windy and sandy conditions, etc. The rich adaptability and stability of the application scenarios have contributed to their successful certification.
"After passing the DIBt verification, our PV modules can be used as building components in local German PV carports, agricultural PV and other overhead installation scenarios." The relevant person in charge of Phillip Solar said that Chinese products stepped into Europe's building-integrated PV market, breaking the technical and market barriers that have long been constructed by local European module manufacturers.
From "steel backbone" to "photovoltaic long sail", the new area enterprises with a composite steel plate, a set of photovoltaic modules to industrial innovation into the map of major projects. Yangzi River on the frame of steel, the European continent erected domestic photovoltaic panels, the new area enterprises are cutting-edge technology, innovative products continue to refresh the industry perception, reshaping the industry benchmark.
