Top 10 Low Relaxation pc strand Manufacturers

January 03, 2026
Low relaxation PC (Prestressed Concrete) strand is a high-strength steel wire used in pre-tensioned and post-tensioned concrete structures. It exhibits minimal long-term deformation under load, ensuring structural stability and durability. Widely used in bridges, high-rise buildings, and infrastructure projects, it offers superior tensile strength, corrosion resistance, and dimensional stability. Compliant with international standards (e.g., ASTM A416, ISO 6067), low relaxation strands enhance safety and reduce maintenance costs in demanding construction applications.
