Sideli high-carbon PC wire/strand is described with SWRH77B/82B and1x3/1x7 structure references. Actual diameter labels are9.3,12.7 and15.2mm.

Confirm finished construction and diameter

The2/3/5/7/9mm raw-material diameter list differs from actual options. Request the strand drawing and distinguish constituent wire from finished assembly measurements.

• Sideli is the brand reference.
• SWRH77B/82B are grade references.
• Three diameters are selectable.
• 1x3/1x7 structures are described.
• Coil form is referenced.

Verify the mechanical test basis

1770/1860MPa are alternative tensile references. Relaxation less than2.5% and elongation2.5% need actual test conditions.

Agree coil and application acceptance

Coil mass is independent of diameter. Request actual material and assembly tests;construction/cold-heading labels do not establish structural approval or a finished system rating.
