High Vanadium Closed Cable Helps Chengdu Phoenix Mountain

With the smooth opening of the large-open cable dome structure of the professional football stadium in the Phoenix Mountain Sports Park in Chengdu, the zinc-aluminum-rare earth alloy-plated closed cable was successfully used again in international and professional high-quality stadiums.

  Phoenix Mountain Sports Park is the core venue of the 31st World University Summer Games in Chengdu in 2021 and an important venue for the 18th Asian Cup in 2023. It is the overall strategic deployment of the "Three Cities and Three Capitals" by the Chengdu Municipal Committee and the Municipal Government. A major project to accelerate the pace of construction of world-famous cities. The project includes a professional football stadium that meets FIFA standards and 60,000 seats and a comprehensive gymnasium that meets NBA standards and 18,000 seats. Upon completion, it can not only undertake international and domestic top-level competitions but also meet the professional training of youth football. And sports exchanges, exhibitions, commercial performances, large-scale variety, tourism, and other functions.

  Editor's note: The roof of the professional football stadium in Phoenix Mountain Sports Park is the country's first large-open cable dome structure, with a maximum cantilever span of about 64 meters, a north-south span of about 279 meters, and an east-west span of 234 meters. The outer ring is a double-layer reticulated shell, the inner ring is a triangular three-dimensional truss (low at the south end and high at the north end, the highest point is 63 meters high), and a sunflower-shaped cable dome is located between the outer ring and the inner ring.

  The closed cable for large-diameter building structures successfully developed by Guizhou Steel Rope Independent Innovation has unique advantages. It is mainly used in roof structures and curtain walls of large buildings such as hangars, gymnasiums and exhibition halls. The important components of the curtain wall structure have reached the international advanced level in technical indicators and were successfully used in the Guizhou Tongren Olympic Sports Center for the first time in 2018 instead of imports, which opened a new course in the development of closed cables for building structures in China. In December 2019, the Standard for Sealing Cables for Building Structures was approved by the National Standardization Management Committee and included in the fourth batch of recommended national standard plans for 2019.

  In August 2019, "Large Diameter Zinc Aluminum Rare Earth Alloy Coating Fully Sealed Wire Rope" won the Guiyang Industrial Products Expo 2019 Excellent Design Award. This indicates that the full-closed cable of the large-diameter zinc-aluminum rare earth alloy coating not only reaches the international advanced level, but also fully considers the safety, reliability, environmental adaptability, and economy of the product life cycle when designing, which meets the requirements of the steel wire rope. It has excellent stress state and comprehensive performance. It has the advantages of smooth and beautiful appearance, strong bearing capacity, large elastic modulus, good anti-rotation performance, long service life, and corrosion resistance. It provides a guarantee for the lightness, beauty, and reliability of the building membrane structure.
