Recently, at the Xella Germany License Partner Conference held in Berlin, Germany, Shen Xiaohe, President of UBlok, and Christophe Clemente, Global President of Xella Germany, signed an agreement on deepening cooperation. Both parties agreed to strengthen collaboration in technology, market expansion, and brand building in response to the uncertain global economy and market environment. They committed to working toward mutual goals, walking hand in hand, and achieving mutual success, aiming to play a greater role in the development of the global aerated concrete industry.

Shen Xiaohe stated, "As UBlok, a company deeply rooted in China—the world’s largest aerated concrete market—learning from and drawing on the experience of Xella Germany is of long-term constructive significance for UBlok’s sustainable development. Xella Germany, as Europe’s largest and most time-honored enterprise in the field, owns two world-class brands: YTONG and HEBEL, and has accumulated rich expertise in technology development, energy conservation and carbon reduction, and joint restructuring."

It is reported that Xella is the world’s largest "white wall materials" company, mainly producing two major product lines: aerated concrete and lime-sand bricks (blocks). The YTONG brand has a history of over 100 years. In 2024, its global revenue reached 985 million euros. In 2017 and 2019, UBlok acquired all of Xella’s business operations in China, including the production bases located in Changxing, Zhejiang, and Tianjin, and has since become Xella’s strategic partner in China.
