Weathering steel helps to build competition venues for 2022 Winter Olympic Games

A lot of steel materials are needed for the 2022 Winter Olympic Games. The weathering steel Q355NHD for construction is mainly used for the construction of the first bid section of national alpine skiing center competition venue. The construction area of the project is 47097 square meters. It designs 11 skiing events such as super big turn, big turn, turn and slide for men and women. It is the landmark competition venue of the whole Winter Olympic Games and the building with the highest difficulty coefficient. Due to the harsh climate of the natural forest scenic spot, the construction party has put forward higher requirements on the performance of building materials and environmental protection. Weathering steel for construction perfectly caters to these needs.

These weathering steel for construction meet the coating free requirements and Z-direction performance requirements put forward by users, that is, to ensure the performance index of weathering steel plate thickness direction. The field technicians optimize the optimal scheme from a variety of components and process systems, accurately control the process window, adopt the ultra-low temperature and multi-stage control rolling method, and complete the trial production and process evaluation in a short time. It effectively guarantees the atmospheric corrosion resistance index and various performance indexes of the weathering steel plate, provides high-quality products for the smooth construction of key projects of the Winter Olympic Games, and at the same time promotes the construction weathering steel to shine in the national key projects.
