Wiking® Macro Fibres are monofilament polypropylene fibres, especially developed to increase the ductility and tensile strength of concrete. The fibres effectively protect the concrete against stresses and external impacts – serving as a superior alternative to steel mesh.
Products include:
Short macro fibres for increasing tensile strength of concrete, especially suitable for high-strength concrete with silica fume.
Long macro fibres for increasing tensile strength and joint spacing, especially suitable for shotcrete and concrete elements.
3rd generation macro fibres with an increased specific gravity of above 1.0, which ensures that the fibres do not appear on the concrete surface.

- Product description
-
Wiking® Macro Fibres are made of 100% virgin polypropylene, which has been extruded, oriented, shrunk and subsequently cut in lengths as required. The macro fibres provide a high level of tensile strength and may serve as a cost-effective alternative to steel mesh and bars.
Increased tensile strength
When the Wiking® Macro Fibres are added to the concrete mix, the fibres will form a three-dimensional matrix in the mix and cause for the tensile strength to increase earlier in the drying/hardening phase. As a result, the formation and growth of cracks is prevented, leading to a more durable and strong concrete structure.
Specific gravity of above 1.0
Contrasting to steel fibres, our 3rd generation macro fibres named Wiking® 4050SP do not appear on the surface of concrete. This is because, Wiking® 4050SP fibres have an increased specific gravity of above 1.0, which prohibits them from floating to the surface of concrete. As a result, the concrete product will have a more aesthetic finish and the durability of the structure will increase.
Flexible production that meets your need
We have a flexible production line which easily meets individual customer requirements. Our Wiking® Macro Fibres can be cut into specific lengths or delivered in tow. We also offer special coating for enhanced bonding and an on-site fibre cutting machine for improved efficiency on the building site.
