Managing Director of Barad Precision Technology Engineering Company, Mr. Seyed Mohammad Hassan Asadi, in 1371, for the first time in Iran, succeeded in producing precision brass and copper pipes in such a way that in addition to the outer diameter, they also had the ability to reduce the pipe thickness and adjust the inner diameter. .

At that time, the most users of these pipes were sanitary valve and car radiator factories, which they operated with their partners under the name of “Tavana Sanat Lulu” company, and important companies such as Hero Valves, Soreeh Radiator and Also, various chandelier production companies were among the main customers of that company.

But the influx of Chinese goods gradually caused the closure of the work, and almost until 2003, all their activities in this field were stopped.
