KOREFIB® FiberMesh 3 mm Composite reinforcing mesh for concrete 3×100×100
Composite reinforcing mesh roll 3×100×100
A composite reinforcing mesh roll for fast placement in concrete floors, screeds and non-load-bearing construction layers. Suitable as a lightweight replacement for welded steel mesh where easy handling, corrosion resistance and long service life are decisive.
Enter the welded steel mesh from your design or the layer thickness - the tool will recommend a matching KOREFIB® FiberMesh.

Indicative aid - does not replace design documentation. The tensile strength is the average of the longitudinal and transverse directions (FiberMesh per ETA 25/0367, steel converted from a 500 MPa yield strength). The recommendation by layer thickness is the manufacturer's experience-based choice, not a structural calculation. It applies to the anti-shrinkage function in non-loaded screeds and floor screeds up to 150 mm, not to load-bearing reinforcement. The specific use must be approved by a designer or structural engineer. Detailed guide ›

KOREFIB® FiberMesh 3 mm
A composite anti-shrinkage reinforcing mesh with a 100×100 mm mesh spacing and a 3 mm bar diameter. A universal variant for cement and anhydrite screeds, floor layers and structural toppings, where the reinforcement is meant to limit shrinkage cracks and distribute tensile stress across the area — corrosion-free and at a low weight.
The 3×100×100 variant is supplied with CE marking and ETA documentation (ETA 25/0367). It serves as anti-shrinkage and distribution reinforcement in non-loaded layers, not as load-bearing reinforcement.
The 3×100×100 variant is the most universal choice for screeds and floor layers in residential and commercial areas. It offers a balanced tensile strength, low weight and a favourable price, and is suitable for most common anti-shrinkage applications.

Available sizes
Difference between variants
50×50 mm mesh spacing. A denser grid for thinner screeds and light layers, where finer crack distribution is needed.
100×100 mm mesh spacing. A universal choice for screeds and floor layers in residential and commercial areas.
100×100 mm mesh spacing. A thicker bar for thicker screeds and structural toppings with a greater layer thickness.
All variants serve as anti-shrinkage and distribution reinforcement. Not sure which to choose? Send us the layer build-up and the intended use, and we will recommend a suitable variant.
