Q131 Reinforcing Steel Mesh
Q131 mesh is a square-pattern (Q-type) welded reinforcing fabric with approximately 5 mm wire at 150 mm pitch, delivering 1.31 cm²/m cross-section in both directions. Produced to DIN 488-4 / EN 10080, it is the lightest standard Q-mesh size — ideal for lightly loaded slabs, screeds and ground-bearing floors.
Q131 Mesh: Technical Definition
Q131 is the DIN 488 type designation for a square (Q = quadratisch) welded reinforcing fabric where both the longitudinal and transverse wires have an identical cross-sectional area of approximately 1.31 cm²/m. The wire diameter is nominally ≈ 5 mm at a pitch of 150 mm in both directions.
The number “131” in the designation encodes the cross-section: 1.31 cm²/m (expressed as 131 mm²/m). Because the mesh is square (Q type), both wire directions carry the same reinforcement area, making Q131 well suited to two-way spanning slabs where equal reinforcement in both axes is structurally efficient.
Standard Sheet Dimensions
Standard Q131 panels are typically supplied as 6.0 m × 2.3 m sheets (nominal dimension; actual dimensions may vary by manufacturer). Each panel has usable overhanging wires at the edges to allow overlapping between adjacent sheets in accordance with EN 1992-1-1 lap splice requirements. Sheet mass is approximately 3.02 kg/m², giving a typical sheet weight of ~41.7 kg for a 6.0 × 2.3 m panel.

Typical Applications for Q131 Mesh
Light cross-section, consistent geometry — Q131 is the go-to choice for several common structural and civil applications.
Ground-Bearing Slabs
Lightly loaded domestic and light-industrial floor slabs on grade, where minimum crack control reinforcement is required rather than full structural design.
Screeds & Overlays
Reinforced screeds, topping slabs and concrete overlays where Q131’s low weight and easy handling speed placement without heavy reinforcement demand.
Lightweight Precast Panels
Thin precast wall and floor panels, filigree slab bottoms and similar applications where a low cross-section mesh is structurally sufficient and reduces dead load.
