Since 2003, Seng Liy has grown from a pioneer in plastic recycling into a sustainability-driven group creating solutions that go beyond construction. What began with turning waste into resources has evolved into an ecosystem spanning sustainable materials, precision manufacturing, green innovation, and digital transformation.
Our name carries our philosophy: drawn from the Chinese characters “诚信” (Integrity) and “立业” (Success), it reflects our belief that true success must be built on trust, responsibility, and lasting impact.
Guided by our promise, “Innovate today for a sustainable tomorrow”, we continue to transform challenges into opportunities, advancing the circular economy and shaping a greener, more resilient future for industries, communities, and the planet.
At Seng Liy Holdings, we drive sustainability and innovation across industries. From plastic recycling and manufacturing to eco-friendly construction materials, each of our subsidiaries plays a role in creating long-term value while minimising environmental impact. Together, we are committed to the circular economy and creating positive change across industries.

We are committed to preserving the environment through sustainable practices, green innovations, and responsible resource management.

We drive progress by embracing cutting-edge technologies and pioneering forward-thinking solutions that shape a better future.

We aim to make a lasting difference by transforming industries, uplifting communities, and delivering purposeful outcomes.

We introduced Gline, a brand offering a wide range of general building materials to serve diverse client needs.

We strengthened Nowa with the launch of our in-house PVC corner bead production line, a flagship product that embodies our ESG values and reinforces our leadership in sustainable building solutions.
We formed Seng Liy Holdings Sdn. Bhd. to consolidate our subsidiaries under one umbrella, enabling greater scale, efficiency, and a sharper focus on innovation and sustainability.
