Find by machineBrowse by machine typeVolka Makina is the specialist company built to take Gültekinler Group's heavy machinery spare parts business into international export markets. Our story began in 1995, when İsmet Gültekin started trading CAT spare parts in Istanbul.
Today, from our headquarters at the Istanbul World Trade Center and our Tuzla Free Zone warehouse, we export to 22 countries, and since January 2026 we have been the authorized regional distributor of Costex Tractor Parts (CTP) for Turkey.
Our story
A business that started with CAT spare parts grew into a multi-sector group run with a holding-company culture, and into international export: three decades of know-how, three generations of supply discipline.
İsmet Gültekin began trading CAT spare parts in Istanbul, laying the foundations of our supply discipline.
Seven years of know-how became a corporate structure and the company officially entered the market.
Hospitality, steel doors, chemicals, coatings and bonded warehousing: a holding active in six sectors.
Led by Baran and İsmet Gültekin, Volka Makina Dış Ticaret A.Ş. was founded to focus on export.
Regular shipments to the Middle East, the Caucasus, the Turkic Republics and Eastern Europe; the Tuzla Free Zone warehouse opened.
We became CTP's authorized regional distributor for Turkey: factory-warrantied parts at direct manufacturer pricing.
The foundation laid by our founder İsmet Gültekin in 1995 grew under the corporate leadership of his son Baran Gültekin and is now being handed to a new generation through his grandson Mehmet Bedirhan Gültekin. Same discipline, same promise, across three generations.
