709.12 Welded Deformed Steel Wire Fabric for Concrete Reinforcement

1. Specification:

709.10, 709.12 C&MS.

S 1068

2. Sampling and/or Inspection Requirements:

All welded steel wire fabric and deformed steel wire fabric shall be inspected after delivery to the project for dimensions, markings and condition. (Field)

Dimensions and/or weight of the wire shall comply with the pertinent table. Dimensions of the fabric and wire size shall be checked against Standard Drawing BP-2 or BP-8 or other applicable drawings, design plans, etc.

The wire shall be assembled by automatic machines or by other suitable mechanical means which will assure accurate spacing and alignment of all members of the finished fabric. Width and length tolerances are shown in section 4. Longitudinal and transverse members shall be securely connected at every intersection by the process of electrical-resistance welding. It shall be fabricated and finished in a workmanlike manner and shall be free from injurious defects.


Each bundle of flat sheets and each roll shall have attached a suitable tag bearing the name of the manufacturer, description of the material, spacing and size of the wire.


Supplement 1068 defines certification requirements for acceptance of reinforcing steel, welded wire mesh, dowel bars and mechanical reinforcing steel splice (RWWS) materials meeting ODOT specifications, 509.08 and 709.00 through 709.14.

The Department will only accept products from Manufacturers certified under this supplement.

For a list of certified suppliers visit the OMM website at http://www.dot.state.oh.us/testlab/

The manufacturer will ship products using the Department's Virtual Warehouse (TE-24) system. When shipping RWWS materials, the Manufacturer will include a Bill of Lading with the Shipping Notice Report to OMM any missing documentation and the company who shipped the materials.

No sample is required. The project may sample any materials they question. Provide sample and copy of documentation to laboratory.

3. Methods of Tests:


ASTM A 82, A 496, A 185, A 370, A 497

4. Addendum:

Welded wire fabric is called out as follows: 4 x 12 -W12 x W 4. This means the longitudinal wire is spaced ever 4 inches and the transverse wire is spaced every 12 inches. The longitudinal wire is the W12 and the transverse wire is the W4
