What is the minimum specified 0.2% proof stress for the steel wire used in the fabric?

500 N/mm² for both plain and deformed wires, as per Table 2.

What is the key requirement for the quality of the weld?

The weld shear strength test. The breaking load of the weld must be at least 25% of the specified characteristic breaking load of the wire, according to Clause 8.3 and Table 3.

What is the allowable tolerance on the spacing between wires?

The tolerance on both longitudinal and transverse wire spacing is the greater of ±7.5 mm or ±7.5% of the nominal spacing (Clause 6.3.2).

Does this standard cover stainless steel wire fabric?

No, this standard is applicable to carbon steel plain and deformed wires. Stainless steel fabric would be covered by other specifications.

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.

Quick Reference Values

Minimum 0.2 percent proof stress500 N/mm²

Minimum Tensile Strength570 N/mm²

Minimum Weld Shear Strength (as % of wire breaking load)25 %

Tolerance on Wire Spacing (Longitudinal & Transverse)±7.5 mm or ±7.5%, whichever is greater

Tolerance on Sheet/Roll Width±25 mm or ±0.5%, whichever is greater

Practical Notes

Ensure the weld shear strength is tested as specified, as this is critical for the fabric to act as a monolithic reinforcement mat.

Verify the markings on delivery, which should include mesh size, wire diameters, and the standard mark (ISI logo) to ensure compliance.

Using Welded Wire Fabric (WWF) can significantly reduce labor time for placing reinforcement in slabs, pavements, and precast panels compared to tying individual bars.
