Borusan Mannesmann

The first industrial enterprise of one of Turkey’s foremost business conglomerates, the Borusan Group, Borusan Mannesmann marked its 60th anniversary in 2018. Having operated with a global vision since its inception, the company merged its operations with Europe’s leading steel and technology firm Salzgitter Mannesmann GMBH in 1998.

Today, Borusan Mannesmann continues its operations as a global brand with 2,038 employees offering more than 4,000 product varieties. Its 7 facilities across 3 continents and high sales volume have placed it on the map as a leading manufacturer in Europe and the world in the steel pipe industry.

Borusan Mannesmann brings its experience, expertise, and passion worldwide with its stateof-the-art pipes addressing all areas ranging from automotive to construction, energy to machinery production. The company continued its investments with a global perspective in accordance with market dynamics and made its first overseas investment in 2001 when it bought the facility in Vobarno and founded Borusan Mannesmann Vobarno Tubi S.p.A. The company then established Borusan Mannesmann Pipe US Inc. in 2014 to manage its Houston Baytown factory investment in the United States. Borusan Mannesmann Pipe US Inc. achieved success soon thanks to its advanced technology and innovative products and won the “Best Pipe Manufacturer” award given by one of the most prestigious publications in the United States, American Metal Market, in 2015, 2017, and 2020.

Having entered among Turkey’s pioneering overseas investors with these breakthroughs, Borusan Mannesman both seeks investment opportunities in different countries and aims to boost Turkey’s competitiveness.

In addition to its contributions to our country with its exports to various countries in America, Europe, Africa, and Asia, it is also a driving force for the Turkish economy with the development assurance it gives for the coming years.

Having been ranked among Turkey’s top 100 industrial enterprises for 50 years, Borusan Mannesmann goes beyond merely manufacturing pipes with its thousands of products, reliable service, quality, and the trails it has blazed in Turkey and the world, and builds Turkey’s future. It delivers a sustainable society with its management policies as well as a developed country and a secure future with its large-scale investments.
