About Us
Our story began in 1965 with the trusted and long-established name of Qazvin Glass. However, we did not limit ourselves to the production of raw glass. Recognizing the growing demands of modern architecture for safety and energy efficiency, we strategically shifted our focus toward the glass processing industry in the mid-1990s.
