The 1×7 PC Strand Production Line is designed for the manufacturing of high-strength prestressed concrete strand used in bridges, highways, railway sleepers, high-rise buildings, and large-span structures.
This production line is engineered for stable operation, high tensile performance, and long-term continuous production, meeting international standards for PC strand manufacturing.
Product Overview
The line produces 1×7 PC Strand (seven-wire structure: 6 outer wires + 1 central wire), with high tensile strength and excellent elongation performance.
It is suitable for:
-
Prestressed concrete structures
-
Infrastructure construction projects
-
PC strand manufacturing plants
-
Upgrading existing wire drawing factories to PC strand production
