The 2022 Qatar World Cup is in full swing. Many netizens ridiculed that apart from the Chinese football team not going to the World Cup, Chinese elements can be seen in every corner. Many people may not know that the Lusail Stadium, where the opening ceremony was held on November 20, was also designed and built by our country.

The steel structure of Lusail Stadium uses about 30,000 tons. The steel structure is divided into 48 V-column trusses, 24 pressure ring trusses, and 48 curtain wall trusses. The steel structure weighing more than 20,000 tons is only supported by 24 spherical joint supports. On the concrete column, after the installation of the 1,000-meter-long compression ring truss is completed, the size deviation of more than 100 cable clamp holes on it is required to be controlled within 25mm, and the construction is very difficult.

With the continuous growth of iron and steel production in China, the proportion of steel structures in buildings is increasing with their own advantages, and steel tube structures have also made a great breakthrough. The pipe rack structure in the steel pipe structure is favored by people because of its unique advantages. At present, it is mainly used in some large public buildings;

In recent years, Huayang Steel Pipe has directly supplied 1000 tons of Q355B steel pipes for the Hangzhou Asian Games bicycle pavilion. The total area of the Hangzhou Asian Games bicycle pavilion is about 8.4 square kilometers, including 6300 mu of water area. The entire bicycle hall is oval, 132 meters long, 101 meters wide, and 32 meters high. It is built with steel structure system, which is rare in China and the largest span steel structure project in Chun'an.

In addition, Huayang Steel Pipe also supplies 13000 tons of Q355B steel pipes directly to Tianjin National Convention and Exhibition Center. The project is constructed in two phases. The total construction area of Phase I is about 800000 square meters, and the total construction area of Phase II is about 580000 square meters. After the project is fully completed, it will provide a large international exhibition venue for the Beijing Tianjin Hebei urban agglomeration.

Huayang Steel will always adhere to the values of "responsibility, safety, quality and excellence" and the business philosophy of "sincerity, trust, professionalism and excellence", and strive to create high-quality products to achieve win-win cooperation.
