Q-type welded wire fabric uses approximately equal reinforcement in the two orthogonal directions. It is commonly specified for slabs, walls, and distributed reinforcement where two-way steel is required.
| Designation | Wire Diameter | Spacing | Approx. Weight |
|---|---|---|---|
| Q188 | 6 mm | 150 × 150 mm | ≈ 2.95 kg/m² |
| Q257 | 7 mm | 150 × 150 mm | ≈ 4.04 kg/m² |
| Q335 | 8 mm | 150 × 150 mm | ≈ 5.27 kg/m² |
| Q424 | 9 mm | 150 × 150 mm | ≈ 6.68 kg/m² |
Specification note: Designations and weights can vary by national standard, manufacturing tolerance, lap length, and coating. Confirm the reinforcement area and certified supplier data before ordering or structural design.
R-type welded wire fabric has a larger reinforcement ratio in the main direction and lighter transverse wires. It is used where the design requires directional reinforcement behavior.
| Designation | Wire Diameter | Spacing | Approx. Weight |
|---|---|---|---|
| R131 | 5 / 4 mm | 150 × 250 mm | ≈ 2.00 kg/m² |
| R188 | 6 / 5 mm | 150 × 250 mm | ≈ 2.53 kg/m² |
| R257 | 7 / 5 mm | 150 × 250 mm | ≈ 3.28 kg/m² |
| R335 | 8 / 6 mm | 150 × 250 mm | ≈ 4.28 kg/m² |
