CEO’s Message

At Seng Liy Holdings, we believe that sustainability and innovation must go hand in hand. Our purpose is not only to address industries’ needs but also to build a greener, more responsible future for generations to come.

My journey began with a strong foundation in manufacturing and business strategy, where I learned the importance of agility, operational excellence, and long-term thinking. These principles shaped the core of our group’s success.

In 2013, I co-founded Seng Liy Engineering to pioneer sustainable building materials that do more than meet functional needs—they promote a circular economy and support Malaysia’s green development goals. Today, as CEO of Seng Liy Holdings, I oversee the expansion of our group into new industries and markets, always guided by values of continuous learning, collaboration, and impact-driven leadership.

I believe that leadership is not just about driving growth, but about making meaningful change. Together, with our teams and partners, we are setting new benchmarks in environmental innovation and industry transformation.
