Give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Ongoing updates and summaries available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Desert photovoltaic mounting structures are faced with deadly threats from sandstorms, saltiness, and alkalinity, which reduces their lifespan by 30%. The Danxia steel, innovatively developed by China Baowu, overturns traditional approaches: it rusts on its own to form a dense rust layer that enables it to resist extreme conditions without any maintenance needs. It reduces weight by 20% while increasing strength, allowing solar panels to remain intact despite being in \"steel graves\". According to the State-owned Assets Supervision and Administration Commission, to address the problem of corrosion-prone nature of solar panel supports in deserts, Baowu Baosteel Co., Ltd. has developed \"Danxia Steel®\", which forms a protective layer through intentional rusting, thereby significantly extending the lifespan of these supports and reducing maintenance costs. In areas such as deserts and Gobi regions, the natural environment is harsh; sandstorms, salinity, and extreme temperature differences cause the galvanized steel frames of conventional photovoltaic panels to rust easily, reducing their lifespan by more than 30% and increasing the frequency of replacements as well as the operational maintenance burden. In the face of such challenges, Danxia Steel® (Baosteel’s hot-rolled super weathering steel) employs special alloying elements and rolling cooling processes to rapidly form a dense, stable protective rust layer in natural environments, thereby preventing corrosion agents from penetrating. Compared to ordinary weathering steel, it has a denser rust layer and higher strength. In the initial stage of use, the color of the steel transitions from gray to brownish-yellow, eventually developing a stable brownish-red color similar to that of Danxia landforms. This type of steel has significant advantages: first, it is highly weather-resistant and can withstand corrosion without the need for additional coatings, thus requiring no maintenance ； Secondly, it saves time and effort, reducing the hassle of manual inspection and replacement ； Thirdly, it is ultra-thin and strong (with a thickness of only 1.5–1.8 millimeters), reducing weight by 20%, making transportation and installation easier, and lowering the project’s carbon emissions by 35%. Danxia Steel® has been used in photovoltaic mounting structures in areas such as the Tarim Oil Field in Xinjiang, ensuring the stable operation of power plants; it has also been widely adopted in projects in mountainous regions, mines, and farmlands across the country.
