DESCRIPTION

PC STRAND (Prestressed Concrete Strand)
PC Strand is a high-performance steel reinforcement product designed for prestressed concrete structures. Composed of multiple high-carbon steel wires helically wound together, PC Strand offers exceptional tensile strength, durability, and flexibility, making it ideal for applications requiring long-span support and load-bearing capacity.

Key Features:

High Tensile Strength: Manufactured to meet international standards (e.g., ASTM A416, BS 5896), with typical tensile strengths ranging from 1,860 MPa to 2,160 MPa.
Corrosion Resistance: Optional epoxy coating or galvanized finishes enhance longevity in harsh environments.
Uniform Stress Distribution: Precision engineering ensures consistent performance under dynamic and static loads.
Versatility: Available in diameters from 9.53 mm to 15.7 mm and customizable lengths to suit project requirements.

Applications:
Widely used in bridges, high-rise buildings, railway sleepers, nuclear power plants, and precast concrete elements. Its ability to reduce cracking and enhance structural integrity makes it a cornerstone of modern civil engineering.

Advantages:

Improves concrete's load-bearing efficiency while minimizing material usage.
Complies with stringent quality controls and international certifications.
Enhances project sustainability through extended service life and reduced maintenance costs.

Raw Materials: High-carbon steel wire rods, SWRH 82B，SWRH77B
