The detailed fields consistently identify high carbon prestressed steel strand for concrete related construction inquiries.

Diameter and construction

12.7 mm is among the described nominal sizes, but the actual selection is customized. Confirm the required diameter and choose 1×7 or 1×19 construction rather than assume both configurations meet one project specification.

Tensile and relaxation

Several tensile classes and low relaxation wording are supplied. Tie the requested ASTM A416 Grade270 requirement to a specific proposed strand and its actual inspection records.

• Actual nominal diameter
• Selected strand construction
• Agreed tensile class
• Relaxation test requirements
• Bright uncoated delivery condition

Project acceptance

Railway sleeper and bridge references do not establish project approval. Request applicable dimensional, mechanical and relaxation reports and define the anchorage and installation requirements separately before accepting the proposed prestressing supply.
