Remarks:
- As agreed between the manufacturer and the consumer is allowed not to carry out the test on the impact toughness of the steel reinforcing the class Ac-II (Ac300).
- (Excluded, Edit. Number 3).
- For rebar class A-IV (A600) 18 mm diameter steel rule bending 80°C cold set not less than 30 °C.
- Reinforcing steel grade A-I (A240) over 20 mm at a cold bending by 180 ° with = 2d, class A-II (A300) over 20 mm diameter = 4d.
In bundles, weight 5 tons max., with banding by wire rod 6,5 mm in 6 places min. equally distributed over bundle. Each bundle is provided with 2 steel straps for multiple lifting.
