Recoiled Wire, Welding Steel in Coils for the Reinforcement of Concrete

Recoiled wire

Weldable, sustainable reinforcing steel featuring improved bonding and high ductility, low carbon contents, packaged in coils, hot rolled and cold stretched.

Product characteristics

Excellent uncoiling, even at high speed, as the result of compact packaging with coil-on-coil winding;
Increased output in t/h thanks to reduced machine downtimes for loading and coil format changeover;
Reduced production costs due to less waste;
Compatibility with all welding machines;
Optimized logistics – product high density contributes to reduce handling, transport and storage costs;
Improved bonding – excellent even after straightening;
No axial torsion prevents bar rotation during straightening thus ensuring perfectly straight;
Reduced surface oxidation, giving greater weight yield and enhanced cleanliness;
No welds.

Distinctive elements

Optimisation of production parameters in view of obtaining all products in class C - high ductility, guaranteeing:

Optimal mechanical properties for seismic and other applications;
Less production energy required;
Reduced wear of straightening rollers on pre-bending machines;
ICMQ ECO sustainability label;
LEED credits;
Recycled content certification.

Mechanical features

The standardisation of the production process made it possible to obtain the homogenisation and repeatability of the mechanical characteristics.
The high ductility of the product is expressed by the following parameters:

Optimised tensile strength/yield stress ratio at the minimum and maximum values set out by design standards;
High elongation at maximum AGT load;
A guaranteed yield stress value with limited maximum value.
