(Source: www.people.com.cn) On December 30, 2019, the Beijing-Zhangjiakou Railway officially opened to traffic. As an important part of the Beijing-Lanzhou corridor of the "eight longitudinal and eight transverse" high-speed railway network, the railway line will boost the integrated and coordinated development of the Beijing-Tianjin-Hebei region and ensure the traffic services.

It is reported that along the Beijing-Zhangjiakou Railway, there is a maintenance station every 20-30 kilometers, where the maintenance staff conducts logistical services for the railway line. It also provides accommodation to the staff. In this project, 3TREES Engineering is responsible for the supply of coatings for the facade of staff housing along the high-speed rail line and guiding the painting operation to give the workers a warm home.

Three types of high-performance coatings have been used in this project: high-performance crack-resistant textured decorative coatings, which are rich in expressive power; high-performance anti-stain and elastic exterior wall latex paints, which can resist cracks on cold and dry walls during winter season in northern areas; and high-performance weather-resistant engineering exterior wall paints, which are weather-resistant and alkali-resistant. The efficient combination of the three high-performance paints provides perfect protection for the housing.

In terms of color matching,  3TREES Engineering has chosen a combination of beige, grey and blue (symbol color of the police), representing dream and future and echoing the brightness and purity of ice and snow, so that passengers traveling on the train can feel the passion along the railway line.
