Steel wire and welded wire reinforcement for concrete are covered in the United States by ASTM A1064/A1064M — the single specification that replaced four older standards. If your drawings still cite A82, A185, A496 or A497, A1064 is the current document those map to.
What A1064 consolidated
| Superseded standard | What it covered |
|---|---|
| ASTM A82 | Plain wire |
| ASTM A185 | Plain welded wire mesh |
| ASTM A496 | Deformed wire |
| ASTM A497 | Deformed welded wire mesh |
A1064 sets the requirements for wire size, yield and tensile strength, weld-shear strength and finished mesh dimensions. Plain wire, deformed wire and welded mats are all addressed, with deformed wire specified to a higher yield than plain wire. Outside North America the common equivalents are BS 4483 (UK) and DIN 488 (Germany).
A clean import spec states six things
- The A1064 designation (or the BS 4483 / DIN 488 equivalent)
- The mesh style — for example 6×6 – W2.9×W2.9
- Plain vs deformed wire
- The coating — plain or galvanized
- Sheet or roll format
- Any project yield requirement
Putting these six lines on the order is what avoids surprises at pre-shipment inspection.
