The 21st China International Ground and Pavement Expo held in Shanghai Pudong New International Expo Center from March 26 to 28, 2019. Hangzhou Green Valley once again showed various rubber pads and new products to domestic and foreign customers in 2019.

With the development of sports, the sports ground has been upgraded from a single "Paving Material" to a functional "Sports Ground System" , which meets the requirements of both sports dynamic requirements and static construction code.

Green Valley Gym series composited interlocking tiles are developed on the basis of floor mats and other products. In addition to the characteristics of anti-skid and wear resistance, shock absorption and rebound, pressure resistance and weight resistance, and sports protection, the jigsaw puzzle design also allows the product to have construction Convenience, lower paving costs and other advantages.

At the exhibition site in Shanghai Station, the "Chanel Red" floor specially created by Green Valley for Chanel was laid out as a "red carpet" in the library site of "Into Chanel", and the red seats with the words "Mademoiselle Privé" complemented each other with a noble atmosphere. The classic red is particularly striking.
