Koyuncu Gaz Sanayi A.Ş


Koyuncu Ticaret A.Ş. 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 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 several thousands of cylinders at our warehouse in Istanbul and we distribute our products to not only Turkey but also many overseas countries.
In addition to gas equipment trading , we manufacture TPED certified cylinder bundles, filling ramps, 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.
In 2017 our new plant for specialty and high purity gases started operation. We are proud of our competence and production capability to match and surpass most demands.
We combine products and technologies to consistently deliver high quality specialty gas standards and innovative solutions to end users.
