As a provider of critical fasteners for over 3,000 wind energy projects worldwide, Berdan Cıvata produces high-strength anchor cages, tower assembly bolts, and blade studs, among other essential components, from the foundation to the blades. We continue to be an approved supplier in global markets for 7 of the world’s top 10 wind turbine manufacturers.
Founded in 1980 by Mechanical Engineers Hasan and Yunus Şemsi in a 150 m² workshop in Tarsus, Mersin, Berdan has grown significantly over the years. In 2000, we moved to our first factory, spanning 5,000 m² in the Mersin-Tarsus Organized Industrial Zone, with a team of 25, including two engineers. Today, we operate in facilities covering a total of 48,000 m², with 28,000 m² dedicated to indoor production. Our team now includes over 60 engineers and approximately 400 employees, and we remain a trusted partner for high-strength and critical fasteners.
Our capabilities include machining, rolling, threading, heat treatment, and various surface treatment processes such as patented hot-dip galvanizing, electro-galvanizing, zinc flake, and Teflon coatings. These treatments are conducted in our state-of-the-art surface treatment facilities and products are rigorously tested in our industry-leading, accredited test laboratory before being delivered to our clients.
Our products have been integral to some of the world’s most notable infrastructure projects. We supplied the 10-meter-long, 700 kg anchors that support the towers of Europe’s second-longest suspension bridge, Osmangazi, and the world’s longest suspension bridge, the 1915 Çanakkale Bridge. For the Anamur-Cyprus Peace Water Project, we provided B7/2H grade bolts with a 100-year corrosion resistance for the 80 km pipeline running 250 meters underwater. Additionally, we supplied over 800 tons of fasteners for the Kuwait International Airport project and all fasteners for the 93,000-seat Lusail Stadium, the venue for 10 matches, including the final, of the 2022 FIFA World Cup in Qatar.
Our journey into the wind energy sector began in 2008 when we participated in the Wind Energy Fair in Husum, Germany, as the only Turkish company. This marked the beginning of our collaboration with global wind energy giants. Today, we have supplied fasteners for over 3,000 wind turbine projects globally. Our clients include renowned names like GE from the USA, Nordex and Enercon from Germany, Vestas from Denmark, Siemens from Spain, and Goldwind from China. We have also provided fasteners for the Konya-Karapınar project, Europe’s largest solar power plant, with a capacity of approximately 1,550 MW.
In addition to supporting green energy, we harness natural resources to meet our own energy needs, sourcing 53% of our requirements from our 2.5 MW rooftop solar power plants. We aim to increase this to 90% in the future.
