BES Yapı, one of Turkey's leading companies in natural gas hose production, was founded in Istanbul in 1996. BES Yapı began its journey over 20 years ago producing aluminum flexible air ducts under the Best brand name, and in 2004, it started manufacturing flexible natural gas hoses under the name GFS (Gaz Flex Systems).

Exporting to 25 countries around the world, our company is taking confident steps toward its goal of becoming a global brand wherever the GFS brand reaches. A symbol of quality and trust in the countries it exports to, BES Yapı has built its corporate culture on the foundations of accuracy and honesty.

BES Yapı, which manufactures in accordance with international standards and adapts contemporary innovative technologies, has adopted customer-focused marketing as a principle. BES Yapı, which continuously improves itself in terms of quality control, design, and new product development in its laboratory located in its production facilities, has brought new products to the sector. Our company achieved a first in Turkey in 2013 by introducing stainless steel hoses and connection fittings for domestic natural gas installations to the market. This has ensured that natural gas installations are safer.

BES Yapı aims to continue pioneering innovations in the flexible metal hose sector. Demonstrating the same care after sales as before, BES Yapı has always prioritized being there for its customers.
