Since the founding of the Lions of Asia Group of Companies in 1976, our journey has been a testament to unwavering commitment and innovation. We have pioneered advancements in fire safety, blending technology and tradition. Moreover, since the incorporation of McCallister Sdn Bhd, in association and partnership with the Luke Alexander Group of Companies, Pemall USA, Chemori, Solomon Elijah and Fire Safety Science USA, has allowed us to broaden our horizons and diversify our expertise worldwide.

McCallister will play a pivotal role in the full manufacturing of all components of our Fire Suppression Systems and Clean Agents: ECO7, HFC-227ea and FK-5-1-12.

Together, we stand united under a shared common vision – a vision that extends beyond business success to a commitment to making the world a safer place.

In consistent with our Istana Mataram Kingdom’s vision, this vision extends beyond protection — it is about securing legacies and ensuring a future where safety is synonymous with progress. It is a testament to our dedication to not only lead in business but also contribute positively to the communities we serve.

Together, let us continue our journey of innovation, sustainability, and safety. The challenges we face are opportunities for us to showcase the strength of our collective vision. I am confident that with a very dedicated and remarkable professional teams that we have put in place, we will continue to shape the future of fire safety in the protection of lives and properties.

Thank you for your unwavering commitment, dedication, and support.
