On the shore of Lake Khovsgol, known as “Mongolia’s Sapphire”, an eco-tourism upgrade project led by the Asian Development Bank is writing a new chapter. As the largest freshwater lake in Mongolia and an important eco-tourism destination in Asia, this project shoulders the dual mission of protecting the ecological environment of the 2,760 square kilometers of the lake area and inheriting the culture of the Chatan ethnic group. Its core project – the tourist information Service center of Hatgar Village – was fully designed and constructed by Yexing Membrane Structure.

The most notable feature of Lake Khovsgol in Outer Mongolia (also known as Mongolia) is its extreme continental climate due to its high latitude and proximity to Siberia. The temperature difference between day and night and between seasons is huge. Winters are extremely long and cold, while summers are short and mild.
Therefore, membrane structures are highly suitable for the extreme climate of Lake Khovsgol. Why?
This project adopts PVDF membrane material. The characteristics of PVDF also perfectly match the strict requirements of this project for weather resistance, self-cleaning property and aesthetics
Extraordinary weather resistance and UV resistance (the most crucial advantages)
PVDF resin has extremely high stability against ultraviolet rays and can effectively resist the intense ultraviolet radiation in the Kusugur Lake area, preventing the aging, embrittlement and discoloration of the membrane base fabric. This ensures that the membrane structure has a service life of up to 20 to 30 years under extreme temperature differences and sunlight.
Outstanding self-cleaning performance (low maintenance cost)
The surface of the PV coating is extremely smooth and has a “lotus leaf effect”, making it difficult for dust and dirt to adhere.
Rainwater flushing can keep the building clean, which is crucial for lakeside projects located in remote areas and with inconvenient maintenance, significantly reducing the maintenance costs throughout the building’s entire life cycle.
Excellent resistance to chemical corrosion
It can resist the humid air and salt around the lake (although the salt content in freshwater lakes is low, the air is still humid) as well as the trace acid and alkali corrosion in rain and snow, maintaining the stability of the material’s performance.
Good fire resistance performance
PVDF membrane materials can usually meet the B1 grade flame-retardant material standard and will not spread when exposed to fire, which is indispensable for the safety of public buildings.
Rich color options and aesthetic expressions
PVDF coating can be mixed into a variety of long-lasting and bright colors, and the color is stable and not easy to fade.

Despite the severe cold in Mongolia, the senior project manager dispatched by Yexing still remained on the front line to ensure the smooth progress of the project. At present, nearly 90% of the membrane installation has been completed and the project is progressing smoothly. The Yexing team completed this cross-border landmark project with exquisite craftsmanship, not only highlighting the technical advantages of membrane structures in ecological buildings, but also confirming through international engineering practice that China’s membrane structure technology has entered the world’s leading ranks.


With this project, Yexing Company once again demonstrated its technical strength in the field of membrane structures and its ability to manage cross-border projects. This architectural gem standing by Lake Kusugur is not only a model of cooperation between China and Mongolia in the field of eco-tourism, but also another bright business card for China’s membrane structure technology to go global. As the project progresses smoothly, Yexing Company will continue to provide global customers with even better services, allowing more international landmark buildings to shine with the wisdom and craftsmanship of “Made in China”.
