Criterion I600RL Reinforcing Mesh
Full Description
I600RL Reinforcing Mesh
Standard: AS/NZS 4671:2019 — Steel reinforcing materials Designation: I600RL Product Form: Welded steel mesh (fabric)
Product Description
I600RL is a deformed indented welded steel mesh with a specified lower characteristic yield stress of 600 MPa, Rectangle bar configuration, and Low ductility class.
| Designation Component | Code | Meaning |
|---|---|---|
| Profile | I | Deformed indented |
| Strength Grade | 600 | 600 MPa |
| Configuration | R | Rectangle |
| Ductility Class | L | Low |
Orthogonal bars in a rectangular configuration.
Size and Spacing
Unlike bar and coil, mesh designations include bar size and spacing as suffixes — e.g. I600RL92 means 9 mm bar diameter, 200 mm spacing. However, ACRS certifies at the grade level (I600RL): the specific sizes and spacings a firm is certified for are listed on the ACRS certificate and recorded in LTQ data.
Certification Scope
ACRS certification for I600RL mesh confirms that the certified firm's fabrication meets the requirements of AS/NZS 4671:2019 for this grade, including mechanical properties of the parent wire/bar, weld shear strength, dimensional tolerances, and marking requirements.
