The Company produces the reinforcing rolled steel according to the international and national standards:
DSTU 3760:2006 (Ukraine),GOST 5781-82 (international standard),GOST 10884-94 (international standard),STO ASChM 7-93 (Russian Federation),GOST Р 52544-2006 (Russian Federation),STB 1704-2006, 1704-2012 (Belarus),TU U 27.1-23365425-652:2010,DIN 488 (Germany),BS 4449:1997 (Great Britain),BS 4449:2005 (Great Britain),ASTM A615 (USA),ASTM A706 (USA),STAS 438/1 (Romania),SI 4466 (Israel),NT 26.05 (Tunisia),CAN/CSA-G30.18-M92 (Canada),ISO 6935 2:2007
Reinforcing steel bars of nominal diameter from 14 to 32 mm can be manufactured with corrosion protection coating that ensures the marketable state of the reinforcing steel surface up to 90 days.
Bundle and coil sizesReinforcing steel bars are manufactured in 6 to 12 m length and with maximum deviation of -0/+100 mm for standard length. Upon agreement with the customer steel rebar can be manufactured of other length. The bundle weight is up to 5 t.
Steel rebar in coils is produced with weight up to 600 kg and 1100 - 2100 kg.The products are bound with wire rod of 5.5 to 7.0 mm.
The products are marked with label containing the following data:- Name and (or) trade mark of the manufacturer;- Name of the customer;- Contract/specification number;- Country of destination;- Dimension of the steel products (size, length);- Heat number;- Batch number;- Weight.
Note. Content of marking may be changed as per agreement between the customer and manufacturer.
Deformed reinforcing steel can be marked with identification to state the manufacturing company, strength grade etc.
