Q524 Reinforcing Steel Mesh
Square (Q-type) welded fabric with 10 mm wires at 150 mm pitch — providing approximately 5.24 cm²/m cross-section in both directions. Manufactured to DIN 488-4 and EN 10080, Q524 is the heaviest standard 150 mm pitch square mesh, suited to heavily reinforced flat plates, deep transfer slabs, and infrastructure applications requiring a high base reinforcement area before supplementary bars are added.
Q524 Mesh: Technical Specification
Q524 is the uppermost standard square (Q) mesh grade at 150 mm wire pitch in the DIN 488-4 range. The designation “524” encodes the nominal cross-sectional area per metre: 5.24 cm²/m (524 mm²/m). Both longitudinal and transverse wires are 10.0 mm in diameter at 150 mm pitch.
Using the standard reinforcing steel weight formula (kg/m = d² × 0.00617), a single 10 mm wire weighs 0.617 kg/m. Q524 thus has an approximate sheet weight of 9.27 kg/m² — the heaviest in the standard 150 mm pitch Q-family. The 10 mm wire cross-section (78.5 mm² per wire) is directly readable from standard reinforcing steel section tables and integrates naturally into Eurocode 2 design calculations.
Standard panel size is 6.0 × 2.3 m. Grade is B500A or B500B to EN 10080. All intersections are joined by electrical resistance welding to the shear-bond requirements of DIN 488-4.

Applications for Q524 Welded Mesh
Where the maximum standard-pitch square mesh delivers structural and programme advantages.
Heavy Transfer Slabs
Deep transfer plates (350–500 mm) carrying shear wall or column loads from upper floors require high base reinforcement. Q524 provides the highest standard As at 150 mm pitch before moving to closer-spaced or bespoke grids.
Flat-Plate High-Rise Floors
In punching-shear critical flat-plate designs for residential towers, Q524 as the distributed field mesh reduces the number of additional loose bar layers needed in non-critical zones, simplifying reinforcement scheduling.
High-Rise →Bridge Decks
Bridge deck slabs exposed to traffic and de-icing salts need robust crack-width control per Eurocode 2 and EN 1992-2. Q524 B500B provides the cross-section and ductility often required by bridge deck reinforcement schedules as the continuous slab mesh.
Infrastructure →Heavy Industrial Floors
Port aprons, heavy vehicle maintenance bays, and primary processing plant floors with very high wheel loads (50+ tonnes) frequently specify Q524 as the base mesh to control reflective cracking through the full slab depth.
Foundations →Precast Structural Elements
Heavily loaded precast beams and columns use Q524 as a peripheral cage element in combination with main longitudinal bars; the mesh maintains bar spacing and provides confinement contribution in compression zones.
Precast →Raft Foundations
Mat foundations for multi-storey structures with heavy column loads benefit from Q524 as the continuous lower mat reinforcement, replacing loose bar grids and reducing fixing time on site.
Foundations →Standards, Grade, and Export Documentation
Q524 is manufactured to DIN 488-4 and the European harmonised standard EN 10080. Wire grade is B500A or B500B — 500 MPa minimum characteristic yield strength (fyk). B500B (k ≥ 1.08, Agt ≥ 5.0%) is the preferred grade for structural applications requiring Eurocode 2 ductility class B; B500A (k ≥ 1.05, Agt ≥ 2.5%) is adequate where normal ductility suffices.
The 10 mm wire — cross-section 78.5 mm², weight 0.617 kg/m — is one of the tabulated standard wire sizes in DIN 488-4, ensuring straightforward traceability between the product data sheet and the structural engineer’s reinforcement schedule. Every shipment from Steel Rebar Germany includes:
- EN 10204 Type 3.1 Mill Test Certificate — chemical composition, Re, Rm, Agt, dimensional checks, heat traceable
- CE Declaration of Performance per EN 10080 / Annex ZA
- Certificate of Origin (chamber-stamped or notarised)
- Packing list: bundle dimensions, sheet counts, gross / net weights, container load plan
- Seaworthy packaging — wire-bound bundles, moisture-inhibiting wrapping for FCL or break-bulk freight
