The Fibres

Twintec predominantly uses undulated steel fibres. The highly resistant AFT (Advanced Fibre Technology), characterised by its shape, allows a perfect reinforcement of concrete.

The Fibres

Twintec steel fibre reinforced concrete (SFRC) technology is the result of an extensive research and development programme.

Only experienced and competent concrete flooring contractors master the specific application methods of steel fibres in concrete.

In addition to its advanced understanding of steel fibres in concrete and steel fibre technologies Twintec has developed a number of design tools and production processes (involving specially designed equipment, levelness and flatness control skills) resulting in high quality, cost effective flooring systems able to meet all aspects of clients' requirements.

Twintec predominantly uses undulated steel fibres. The highly resistant AFT fibre (advanced fibre technology) is characterised by its shape and allows a perfect reinforcement of concrete. Extensive testing has confirmed that the undulated shape is a key factor leading to optimal anchorage.

By adding high dosages of steel fibre, the concrete will behave like a composite material with an important gain in structural ductility and shrinkage control. With such rotation capacity, most designs are based on the yield line theory
