EPD document prepared for Tosyalı Demir Çelik Hot Rolled Steel Coil with registration number S-P-04880 has been registered and published in EPD Turkey and The International EPD System. Registered EPD document applies to all global markets.
The purpose of the flat rolled process is to turn blocks of heavy steel from continuous casting into usable sheets or coils. Contrary to the hollow rolls used in the production of structural steels and profiles, round rolls with very smooth surfaces are used in flat rolled product rolling. Because the products are thin and wide, they are called flat products. Hot rolling is the process of hot forming of slabs heated to rolling temperature by rolling. The facility where this process is carried out in TOSÇELİK is the Hot Rolling Mill. TOSÇELİK Hot Rolling Mill has a capacity of 2.000.000 tons/year. In hot rolling, 170 – 210 mm thick slabs are rolled into 1.0 – 10 mm thick, 530 – 1000 mm wide coils. The slabs are first rolled to a thickness of 25 – 35 mm by heating to approximately 1250 degrees. This process, which is done at a temperature of 1100- 1200 degrees, is called pre-rolling, rough rolling. After rough rolling, the material is rolled to its final thickness. This process, which is done in the range of 800-1100 degrees, is called strip rolling. Before the strip material is wound into a coil, it is cooled with water up to 500-750 C degrees according to the desired mechanical properties.
Tosçelik Profil ve Sac Endüstrisi A.Ş.
Tosçelik Profil ve Sac Endüstrisi A.Ş., which operates under Tosyalı Holding, was established in 1997 in Iskenderun Industrial Zone for industrial pipe and box profile production.
Ranked in the ISO 500 list for the first time in 2000, Tosçelik established Turkey’s most modern spiral pipe plant with the largest capacity in Osmaniye Industrial Zone in 2008. The plant started production at the beginning of 2009.
Continuing its investments without slowing down, the company produced the first special hot rolled flat product in 2009 at Tosçelik Osmaniye Structural Steel Production Plant, which had been constructed in 18 months. This investment stands out as the first flat steel production facility constructed from scratch by the private sector of the Republic of Turkey.
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 facility is attentive to environmental properties. The dust and gas that will spread to the environment will be absorbed with the dedusting facility with a cost of 20 million euros. Dust emissions are realized at a rate of half the European Union standard at this facility.
In 2011, the Company ranked 25th in the ISO 500 list with its exports made under the Tosçelik brand. With its investments made with the motto ‘Turkey’s global steelmaker’ and export volume increasing every year, the Company continues to rank among the top 20 companies in every edition of ISO-500 list, climbing up steadily.
In 2012 the pipe and profile plant started production in Osmaniye Organized Industrial Zone. The plant is Turkey’s largest and Europe’s second largest manufacturer of ERW pipes and has the largest indoor space under a single roof, in Europe.
In 2013, the plant joined the Turquality Brand Incentive Program, the first and only branding program in the world, under the brand of Tosçelik. The company is in its second 5th year under the Turquality program and maintains efforts to keep Tosçelik among the world’s leading brands.
In 2014, Tosçelik became one of the main suppliers for the Trans-Anatolian Natural Gas Pipeline Project (TANAP), one of the world’s leading projects. In the TANAP Project, Tosçelik supplied approximately 470 km of the 1850 km long line, which is approximately one third of the total need.
ERW pipe and profile plant was commissioned in 2016 in Dilovası / Gebze.
In 2016, Tosçelik ranked 90th out of the top 1000 companies among 61,000 exporters and was awarded ‘the Company with the Largest Export Breakthrough’ at the TIM’s (Exporters Council of Turkey) ‘Export Champions’ ceremony.
Tosçelik opened its R & D Center in Osmaniye in 2017, making a difference in the sector since the very first day it was founded with an aim to produce strongly innovative, value-added products, As the first in its region, the R & D Center is also the home base of the research and development activities in all production facilities of the Group.
With awareness of its responsibilities in terms of sustainability and energy efficiency, Tosçelik established a solar power plant in 2017 on the roof of the Tosçelik pipe and profile facility in Osmaniye Organized Region. Through this investment, it has the potential to become the ERW pipe manufacturer with world’s lowest carbon footprint. With a rooftop area spanning 200,000 m², the plant has become one of the top five roof-type solar power plants in Europe and the largest in the world.
Exporting products to 135 countries, Tosçelik continues its activities that shape the industry, and its local and international investments that will contribute to the country, people and nature.
