The annual capacity amounts 2,6 million tons of crude steel and turnover is about 2 billion USD. BMZ is one of the five biggest companies in the Republic of Belarus. Our most important advantage is the geographical location in Eastern European region, the own steel production, the flexibility for technical and commercial matters, as well as favourable cost situation.
The export share is about  80 per cent.  The main volume of products goes to the EU and Russian markets. Europe is 37 per cent, the Russian Federation – 35 per cent, Middle East and Africa – 22 per cent , America – 5 per cent, CIS-countries - 1 per cent, countries in Southeast Asia – 0,15 per cent. In 2013 our plant has supplied its products to 114 countries throughout the world, proving that the trademark «BMZ» is widely recognized in the steel goods market. BMZ products are designated for construction, engineering, automotive, and the oil and gas industries.
The Byelorussian Steel Works holds 55 certificates of conformity for different types of products (hot-rolled reinforcing bars, cold-deformed reinforcing wire, pipes, fibre), which allow use of the СE marking for hot-rolled sections of construction steel and hot-rolled seamless pipes. Besides this, our plant holds eight certificates of conformity for its quality systems according to the requirements of many international standards: STB ISO , ISO 9001:2008; ISO/TS 16949:2002; BS EN ISO 9001; ISO/TS 29001, API Spec Q1, AD 2000 Merkblatt W0 and EN

7. Light section wire rod and mill construction
In 2014 our key project is construction of a new rolling mill. It will be one more section rolling mill with the possibility to manufacture around 700 thousand tons of product per year with the prospect of reaching an annual output of 1 million tons. A long-term partner of BMZ – the Danieli company – will give the opportunity to balance production, increase the output of steel cord and wire and increase the volume of manufactured wire products. In the next three years, BMZ, owing to modernization and the reconstruction of steelmaking production, is going to reach 3 million tons of steel. Considering the capacity of the rolling production facility there is an excess amount of concast billets and blooms of around 700 thousand tons. That excess amount will be processed in a new mill. The new rolling shop with will include seven production areas. Around 224 people will work in the new rolling shop.

BILLETS INSPECTION AND PROCESSING LINE:
Is designated to detect and eliminate defects of steel-melting production that can influence on quality of outer surface of finished rolled sections.
Billet inspection and processing line is a technological line where quality control is carried out and billets surface is grinded prior to their transfer to rolling production: concast billets section 140х140 mm (length 8-12 m) and blooms section 250х300 mm (length m).
Capacity of inspection line for concast billets section 140х140 mm – tons per hour, for blooms section 250х300 mm – tones per hour. Productive capacity of the line depends on grinding method: complete surface or local areas.
