IS 16088:2013 is the Indian Standard (BIS) for welded plain and deformed steel wire fabric for concrete reinforcement - specification. This Indian Standard specifies the requirements for factory-made welded steel wire fabric, using plain or deformed wires, intended for the reinforcement of concrete structures. It covers material properties, manufacturing criteria, dimensions, tolerances, mechanical properties like tensile and weld shear strength, and testing protocols.
Specifies requirements for welded plain and deformed steel wire fabric used as reinforcement in concrete.
BIM-relevant code. See the BIM Hub for ISO 19650, IFC, and LOD/LOIN frameworks used alongside it.
| Parameter | IS Value | International | Source |
|---|---|---|---|
| Minimum Yield Strength (Common Deformed Grade) | 500 MPa (for Grade Fe 500D) | 550 MPa (for Grade 80) | ASTM A1064/A1064M - 21 |
| Tensile Strength / Yield Strength Ratio | ≥ 1.08 (for Fe 500D) | ≥ 1.25 (for wire used in seismic applications, though not a general requirement) | ASTM A1064/A1064M - 21 |
| Minimum Elongation (Ag) | 12% (for Fe 500D) | Not directly specified in the same manner; elongation at fracture is specified instead (e.g., 4.0%). | ASTM A1064/A1064M - 21 |
| Weld Shear Strength Requirement (Force) | ≥ 0.25 × fyk × A (e.g., 125 × A Newtons for Fe 500) | ≥ 241 × A Newtons (based on 35,000 psi requirement) | ASTM A1064/A1064M - 21 |
| Nominal Wire Diameter Range (Deformed) | 4.0 mm to 12.0 mm | 5.0 mm to 12.0 mm (for Grade 500L wire) | AS/NZS 4671:2019 |
| Carbon Equivalent (Max) | 0.42 (for Fe 500D) | 0.45 (for B500A/B/C) | BS 4483:2005 (referencing BS 4449) |
| Rebend Test | Mandatory for all diameters | Not required | ASTM A1064/A1064M - 21 |
