Le rond à béton de Sidenor est fabriqué selon un procédé élaboré permettant d’obtenir des aciers avec de bonnes caractéristiques garantissant :
Ribbed reinforcing bars are obtained by hot-rolling processes. It is primarily used to form the reinforcing steel for reinforced concrete structures.

Resistant: More Savings
The RB 500 W is characterized by a minimum strength of 500 N / mm2 against 400 N / mm2 For RB 400. Being more resistant the use of steel RB 500 w allows savings to level quantities of '''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''' steel used, the maximum ''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''economy has reached 35% for columns and an average saving of:
Weldable: More productivity
RB 500W is characterized by its weldability compared to RB 500.This weldability advantage allows a productivity gain with an average yield of ligation of 50 Kg / hour against 80 kg / hour by hand soldering and 100 kg / hour by the electrode welding.
Weldability removes attaching wires and thus makes the reinforcements unalterable when they move; which facilitates handling and transportation. Moreover it reduces the length of hedges bars.
