Define prestressed concrete wire by diameter, surface and an agreed mechanical class.
Grade and tensile scope
The detailed material is SWRH82B wire rod and the tensile range is 1470–1860 MPa. The title requests 1670 MPa, so confirm the actual class rather than assuming one value applies to every supply.
Diameter and surface
The selection is a 4–10 mm range, not separate stock sizes. The title’s 3 mm request needs confirmation alongside plain, smooth, spiral ribbed or indented surface requirements.
- Actual wire diameter
- Selected tensile class
- Surface geometry
- Elongation test basis
- Relaxation and bending records
Acceptance documentation
The source states elongation of at least 3.5% and four bending times without a complete test method. Request applicable reports; low relaxation and certificate references do not independently establish project acceptance.
