Сold-deformed reinforcing steel B500C for concrete construction reinforcement
DSTU EN 10080:2009
EN 10080; ISO 10544
1006, 1008, 1018 are according to SOU MPP 77.140-236; C4D, С7D, C18D are according to DSTU EN 10016.
Furthermore, applying of reinforcing steel class B500C of rated diameter instead of other classes stated above is performed without conversion of reinforcing and coordination with project organizations that is an important factor of production costs reduction and increasing of reliability of steel reinforcement concrete of constructions objects. For the reinforcement of tensile strength 500, the introduction of intermediate sizes in range from 5,5 to 12 mm allows to save steel up to 16% and to solve the problem of interchangeability of working (estimated) reinforcement of one tensile class with reinforcement of the other class.
Rolled steel according to the current TU U DP 24.3-02070766-002:2015 is intended for reinforcement of steel concrete constructions in standard industrial floors, strip foundations, roadway paving, operated in the open air, in heated and not heated locations.
4,0 - 8,0 mm
Advanced manufacturing technology of reinforcement class B500C implemented on “DNIPROMETYZ TAS” LLC allows to produce steady reinforcement with required characteristics in the range from 4,0 to 8,0mm, with any intermediate diameter.

When forming a transport package in bars, each package is tied tightly in three places by wire rod of diameter 5,5 - 8,0mm. On each coil or package at least two clamps are fasten for fixing the strops of crane mechanisms providing the mechanized loading and unloading of the goods.
Coils of weight up to 3000 kg
Bars length (L) from 1,0 up to 6,0 m., package of weight up to 300 kg.
