Domestic Subsidiaries


Tosçelik Profil ve Sac Endüstrisi A.Ş.


Tosyalı Holding completed the installation of its integrated iron-steel complex in Osmaniye in 2009 with a $1 billion investment. The complex in the Osmaniye Organized Industrial Zone comprises a steel mill where liquid steel production is performed, a billet production facility where the input materials for long products are manufactured, a slab production facility where the input materials for flat products are manufactured, a hot sheet rolling mill where hot flat products are manufactured, an oxygen production facility, a dedusting unit, and water treatment plants.

The contract for the facility took form in January 2008, and the first field operations began in early April 2008. The steel mill and billet production facilities completed its first interim production on July 14, 2009. With the hot sheet rolling mill and slab mold facilities starting trial production, all facilities went into operation by the end of November 2009, and our Prime Minister Recep Tayyip Erdoğan held the opening for our facility on February 6, 2010 with a ceremony which close to 3,000 invitees attended.

This investment allows for the manufacture of imported flat steel in Turkey and positively contributes $1 billion to Turkey’s current deficit. Our facility reached annual levels of 1.5 million tons of production with the successful work in the first years of its establishment, and it aims to produce 2 million tons annually in 2012. Tosçelik is among the top five facilities in Turkey in steel production with its production figures from 2010.

The facility is attentive to environmental properties. The dedusting facility will absorb the dust and gas that will spread to the environment with a cost of 20 million euros. Dust emissions materialize at a rate of half the European Union standard at this facility.

This investment was the first flat steel production facility made from scratch by the private sector in the Republic of Turkey.

With the completion of the Osmaniye investments, the Tosyalı Group became the first in Turkey and one of a limited number of facilities around the world that could produce all products under the same roof from raw materials to piping profile, the final product.


ERW welded industrial piping and hollow section production began in 1998 at the company, which foundations were laid in the Iskenderun Organized Industrial Zone in 1997. Our company continues its projects and investments with each passing day and put into operation the Tosçelik Galvanized Piping Production Facility and, in 2007, the Tosçelik Natural Gas Piping Production Facility, whose investment began in 2004 and 2005. It has had industrial piping, water and gas piping, and square, rectangular, and special-segment profiles in its production matrix since 2012.


The initial investment for our facility, which has the title of “Largest piping factory established all at once in Europe”, started in late 2010. This investment saw its completion on land of 353,659 square meters in the Osmaniye Organized Industrial Zone, and its first piping production took place in the fourth quarter of 2011. Our company serves domestically and internationally, primarily including the United States, Europe, and the Middle East. It provides an expansive array of services in the sector, adding EPOXY-, PE-, PP-, and PU-coated piping, sensitive and mechanical piping, piping for pressure purposes, and heat-treated piping and profiles to its production matrix with its enormous factory that has the latest production technology.

In the IPE profile group from 80 mm to 160 mm.

Our own laboratories perform cast-based tension tests, chemical tests, bending tests, and charpy impact test for all products we manufacture.

We do all quality system documentation monitoring and checking using the QDMS system. The SAP System and our database records all kinds of information belonging to our products. The barcode system on the package labels provides traceability until the product reaches the customer.

Tosyalı Iron Steel manufactures these products by heating section squares #130 and #150 of the billet raw material up to 1250 degrees and produces them through hot shaping between the rolling presses. Hot shaping especially makes these materials, and they gain a more durable structure originating from the homogeneous shrinking of particle sizes.

These materials that we produce find use in all buildings of steel construction, all industries in that conduct machine manufacturing, and in various structures, primarily including energy transmission lines.
