On the afternoon of May 30, Rao Deliang, Secretary-General of the Guangdong Door Industry Association, along with Executive Secretary-General Wang Shenghua and their delegation, paid a visit to the headquarters production base of Zhongshan Lianheqiang Sealant Strips for inspection and guidance. Lu Jialian, Chairman of Lianheqiang, together with Sales Director Liu Qing’ai, Technical Director Chen Qian, Deputy General Manager and Sales Manager Liang Zhijian, and other members of the company’s core team, extended a warm welcome and accompanied them throughout the tour.
During this fact-finding visit, both sides engaged in comprehensive and in-depth discussions on key issues such as the collaborative development of the door industry’s value chain, the iterative upgrading of sealing system technologies, and pathways for high-quality industry growth. Through candid and constructive exchanges, the two parties further strengthened their consensus on cooperation, laying a solid foundation for future joint progress.
Chairman Lu Jialian provided the association’s leadership with a detailed overview of Lianheqiang’s development journey since its founding in 1990, including its business strategy and core technological expertise. During their tour of the R&D and testing center, the product showroom, and the display of global engineering projects, the association’s leaders expressed strong appreciation for Lianheqiang’s corporate strength, technical depth, and extensive project experience. Secretary-General Rao Deliang remarked sincerely, “The company boasts profound roots, outstanding capabilities—truly, we wish we had met much earlier!” This high‑level endorsement from the industry association not only serves as encouragement for Lianheqiang’s more than three decades of steadfast dedication but also fuels our resolve to keep forging ahead.
