    and stand out for their excellent quality, high reliability and particularly innovative features.

    The production facilities are continually being upgraded through an extensive long-term investment

    plan exceeding EUR 860 million, for the last 15 years.

    Stages of development 1962 - 2017

    In 1962 Sidenor was established as Viohalco - Sanitas. Today Sidenor is a vertically integrated Group of companies with production plants in Greece, Bulgaria, Romania, FY-ROM and Australia.


    The establishment in Southeast Europe started in 2001 with the acquisition of the Bulgarian plant Stomana Industry, in which Sidenor Group makes continual investments aiming to increase its production capacity, improve quality, decrease production costs and also manufacture high added value products.


    In 1999, Sovel started production at its rolling mill and in the second half of 2001 the steel melting plant.


    In 2006, Sidenor Group strengthened even further its presence in the Balkan market by setting up Dojran Steel in FYROM, which runs a long steel products and mesh plant, mainly for the markets of FYROM and Kosovo.


    From 2007 to 2011 a wide commer-cial network is developed in Serbia (Sidebalk Steel), Albania (Sideral Steel) and Romania (Siderom Steel) in order to fully meet the needs of the local markets and the wider area.

    2007 - 2011

    As part of Sidenor's ongoing in-vestment plan to achieve enhanced quality and product innovations, the installation of the new Vacuum Degasser - VD was successfully completed at the Stomana Industry plant in Bulgaria and also the con-struction and the operation of an induction furnace for the reheat-ing of billets at the Sidenor and Sovel production plants.Major rolling mill revamping in Dojran Steel plant for the pro- duction of a wide range of mer-chant bars.

  • How we ensure quality

    Production facilities boast modern, state-of-the-art quality control laboratories that carry out extensive chemical analyses, metallographic tests, geometric measurements and mechanical tests in order to guarantee that final products fully comply with the requirements of relevant standards and the strictest regulations.

    Sidenor has been working systematically and consistently to ensure the highest possible quality of products and services, always aiming at creating added value for its customers and shareholders. Within this framework, the Company has applied a certified Quality Management System according to ISO 9001. In the production process, the Company focuses on the manufacture of quality products and carries out strict quality controls at all production stages.

    In addition, as regards special steels, online non-destructive testing is carried out in the production lines to ensure 100% the top quality of the products manufactured.

    Sidenor has also installed and operates an integrated radioactivity monitoring and detection system for its raw materials and finished products.



  • Sidenor has been investing in pollution prevention measures and environmental impact investigation and assessment measures, while at the same time the Group is trying to optimise manufacturing processes through the use of Best Available Techniques () established by the EU.

    Sidenor and Stomana Industry are the market leaders in the Balkans in scrap metal recycling. Furthermore, at the facilities of its subsidiaries Aeiforos and Aeiforos Bulgaria in Thessaloniki, Almyros and Pernik (Bulgaria) respectively, Sidenor recycles by-products produced by its plants, thus making a further contribution towards reducing its total environmental footprint. Another initiative undertaken by the Company was the installation of a facility used for direct scrap loading into Sovels electric arc furnace (Consteel), which has made a critical contribution towards reducing the particles and noise produced and the energy required, thus saving valuable natural resources.

    In this context, Sidenor has developed and manages a Sustainability Management System in the aspects of economy, environment, quality, occupational health and safety, society and respect for human rights at the work place.

    Environmental management

    Sidenor has recognized that environmental protection is a key parameter for its operations and a cornerstone of its sustainable development.

    Sidenor and Stomana Industry are the largest steel scrap recyclers in the Balkans.

    Sidenors main actions and initiatives for environmental protection and minimalisation of its environmental footprint are the following:

    Operation of cooling water processing and recycling unit

    Full radioactivity control of raw materials and final products

    Extensive use of natural gas as fuel, due to its superior environmental performance (fewer emissions of particles and CO2 / sulphur dioxide emissions) compared to other fossil fuels

    Analysis and evaluation of the production procees in energy and carbon foot-prints in order to decrease them

    Operation of filters in order to minimize emissions at the steel mills

    Precautionary measures taken to counter pollution

    Evaluation of solid wastes to produce useful products

    Installation and operation of instruments for continuous monitoring of exhaust gases

    Participation in research programs in cooperation with universities and research foundations

    Extensive tree planting in the production facilities

    Systematic control of qualitative parameters of solid and liquid waste and atmospheric emissions, based on analyses conducted both inside the Company and by external bodies
