Tekno is a sole distributer for WIRAND®.Steel Fibers produced by Officine Maccaferri s.P.A whic produces fibers more than 25 years.
The framework with WIRAND®fibres, produced with low carbon steel wire with high pullout resistance, let to obtain an increase in all the resistance mechanical parameters on the concrete and in particular:
- Prevention from crack caused by plastic shrinkage
- Increase of the behaviour of the concrete against thermal variations
- Ability to adsorbe energy during post cracking deflection
- Increase of tensile stregth under flexion load
- Increase of the iimpact resistance
- Increase of resistance to cyclic loads (fatigue)

WIRAND fibres let to reinforce any kind of concrete product with high time saving. Their shaping is very important to grant adhesion between fibre and concrete.
WIRAND fibres find their best application in tunneling, industrial and aeroportual flooring, precast and pre compressed concrete.
Particularly to improve fire resistance of the tunnel final lining, Maccaferri offers polypropylene and cellulose fibres.
The concrete so reinforced allow to:
- Improve fire resistance
- Reduce plastic shrinkage cracking
- Improve freeze/thaw durability
