WIRAND® METAL FIBRESTO REINFORCE CONCRETE ARE
PRODUCED FROM STEEL WIRESWITH A LOW CARBON CONTENT.
THEY ACT AS A THREE-DIMENSIONAL REINFORCEMENT,
ABSORBING THE TENSIONS APPLIED AS A STRUCTURAL
ELEMENT, THUS INCREASING THEIR RESISTANCE

Use of steel fibres to reinforce concrete is continuously increasing in quantity and application. Metal fibre was initially used in two fundamental fields:
Projected concrete for temporary lining of tunnels and clearing concrete in industrial paving works, airports, ports, etc.

This structural reinforcement technology is being used with excellent results in new applications, such as segments or rings for final lining of tunnels, prefabricated units and other concrete structures.
Our fibre FF3 is present in major engineering works, such as the AVE high speed railway line and Line 9 of the Barcelona Metro, with 42 km of tunnel

There are now national and international Regulations and Draft Regulations, both for steel fibres, as well as polypropylene fibres.

Fibres with mechanical resistance to adequate traction and distributed homogeneously in the concrete matrix form a very resistant three-dimensional reinforcement, able to bear appreciable deformations, maintaining good resistance – DUCTILITY – and avoiding propagation of the fissure forming phenomenon, dissipating deformation energy – TENACITY -.

Wirand® steel fibres in concrete provide better behaviour of the structure, as it reduces fissure formation, providing better quality and durability of the work. Other advantages of the use of Wirand® Fibres are elimination, in some applications, of the conventional reinforcement, thus reducing times and labour costs. It also avoids waste of materials and simplifies the tasks of transport, stocking, handling and placement.
