This is our longstanding client from Sri Lanka, with whom we have been collaborating for over a decade. Our main project together has been bidding for projects with their local water board company, and we have supplied them with a large quantity of brass lockable valves, exceeding 300,000 units annually, as well as over 200,000 bronze sleeve valves each year. Over the years, our cooperation has been very pleasant, and the client visits our company every year, always bringing local specialty gifts such as Sri Lankan black tea and gems. They are not only our valued client but also our good friends.
