Koyuncu Tic. Ltd. Sti. was established in 1977 by Mr. Onder Koyuncu as a national industrial gas producer and distributor. Our company mostly focused on the air gases and acetylene until 1990s. Our first gas production facility was located in Eskisehir which is located in the middle part of Turkey. In the late 80s company moved its main operation to Istanbul and established one of the few filling plants on the Anatolian side of Istanbul.

During 1990s company started to focus on the welding gas mixtures. We became a pioneer on this field and we served gas companies all around the country for years.

At the beginning of 21st century, our main business turned out to be gas equipment trading. We currently represent many international gas equipment manufacturers in Turkey. We hold thousands of cylinders in our warehouse in Istanbul and we distribute our products all around Turkey and surrounding countries.

In addition to gas equipment trading , we sell liquefied industrial gases to surrounding countries by semi trailers and ISO tanks. We also rent-out ISO tanks and provide gas free operations to companies in need.
