STRUX® synthetic macro fibres

High strength post-crack protection.

A replacement for welded wire mesh.

Welded wire mesh has long been used to reinforce slab-on-ground concrete, bridge decks and thin-walled precast applications for temperature and shrinkage crack control. Although mesh provides adequate performance, it adds many downsides. The mesh takes time to transport, instal and correctly chair.

STRUX® 90/40

STRUX® 90/40 is a unique, high strength, high modulus, synthetic macro fibre reinforcement that is added to ready mixed and precast concrete at the batching stage. STRUX 90/40 controls drying shrinkage cracking, so it can be used as an alternative to steel mesh and steel fibre reinforcement.

Key Benefits
  • Controls drying shrinkage cracking by controlling the propagation of micro-cracking thus improving toughness and durability of concrete.
  • Can be used as an alternative to steel mesh reinforcement and steel fibre reinforcement.
  • Uniformly distributed throughout the concrete matrix - no risk of incorrect steel mesh reinforcement placement.
Application Type

STRUX® products, such as STRUX® 90/40 synthetic macro fibres, improves impact resistance, durability and long-term crack control properties of concrete by equally distributing structural fibres throughout the entire concrete matrix. There's no risk from corrosion and none of the risk or job site obstruction inherent with the use of welded wire or mild steel reinforcement.  STRUX® eliminates time and labour versus installing welded wire mesh (WWM). It eliminate the need to lift, carry, hoist, position, cut and tie awkward, heavy sheets or rolls of welded wire fabric (WWF) and thus helps to reduce construction time and labour cost for an estimated cost savings between 20-30%. Examples of applications where STRUX® can be used are slab on ground, precast element, elevated deck and tunnel liners  to replace non-structural steel.

Shave off time from construction projects

In today's market, schedule is everything. Transporting, placing and chairing welded wire mesh adds time to any project. STRUX® eliminates all that time—and its material characteristics make it as strong, if not stronger, than the alternative.


Add toughness to concrete with less material

STRUX® fibres add toughness, impact and fatigue resistance to concrete. As opposed to microfibre reinforcement, STRUX® macro fibres add post-crack control performance. STRUX® allows users to save on material by decreasing thickness of slab on grade or overlays. For designers, this increases the range of possible forms. For contractors, this means less material overall may be needed. STRUX® reduces the time required for the critical path resulting in faster construction times and earlier delivery of the building for the contractor.
