Our Vision

The purpose behind our existence.

Our Vision is to become leaders in sustainable manufacturing practices that set the standard for environmental responsibility and social accountability within our industry and marketplace.

Our Values

Meet the Team


Our domestic factory began casting architectural hardware, and exporting to our first UK customers


Growing to a team of 20 dedicated professionals, our company solidified its presence with established UK-based customers.


The company diversified and ventured into sheet steel fabrication, marking a significant milestone exporting premium architectural fabrications to our market leading UK-based partner.




The company expanded its capabilities by introducing a cutting-edge powder coating factory, complimented by state-of-the-art shot blasting and hot zinc spray services.

Embracing a Western-focused approach in our operations, staff management, and community impact - setting us apart from other factories and our competitors with our social responsibility.

We proudly opened a new 47,000 sq. ft. facility, with a skilled workforce of 70 individuals, a testament to our commitment to growth, quality and social responsibility.




We proudly became the first factory in the area to provide 'life insurance' benefits to our valued staff.

Awareness of the evolving emphasis on sustainability moved us to action. While our business maintained a robust commitment to the local environment and community, there arose a necessity to expand our focus globally, especially on climate change.

Marking a pivotal milestone for the business, the opening of our UK office signified another stride in setting ourselves apart from the conventional perception of Indian 'offshore suppliers.'



During 2024 we aim to become a "zero waste to landfill" company, all our waste materials will be fully recycled or re-used with no waste being sent for landfill or incineration - furthering our commitment and vision for a sustainable future.

Praveen Sharma decided that his vision of a company that focused on its “global footprint" needed to be recognised, and the creation of "The Sustainable Manufacturing Company" was completed.


Unifying the two Companies of Bishen International and Crishna International under on new business name and giving the lasting direction for our business to be one of sustainability and social responsibility.
