The project of Vientiane City in Chongqing, Saint Roland: the project covers an area of 100 m2, the outer elevation is 11.2m high, and the front is equipped with a full LED outdoor screen. Due to the need for construction of the whole facade, it is difficult to construct on site, and coordination of all parties is required. High facade has a great challenge to us. During the construction of the project, we actively develop special glass suppliers and actively communicate with the production system to ensure the design effect of the customers on the basis of safety, rationality and cost saving.
