Stress-Relieved Steel Wire is essential in modern prestressed concrete construction, providing the strength and stability needed for long-term structural performance. Produced through a controlled heat treatment process, it minimizes internal stresses and ensures uniform mechanical properties. At DEJIA (Tianjin Dejia PC Steel Strand Co., Ltd.), we manufacture high-quality stress-relieved steel wire with precision and advanced technology to meet the requirements of global construction and infrastructure projects.
Our high-tensile steel wire is designed for outstanding performance in prestressed and post-tensioned applications. It offers high tensile strength, low relaxation, and excellent corrosion resistance, ensuring durability under continuous load. The wire also features superior ductility, a uniform surface finish, and compliance with international standards such as GB/T, ASTM, and BS.
High tensile strength for reliable load-bearing capacity.
Low relaxation for stable long-term tension.
Excellent fatigue and corrosion resistance in demanding environments.
Consistent mechanical performance across production batches.
We provide a wide range of Stress-Relieved Steel Wire options to suit various engineering needs. Available in multiple diameters, tensile grades, and surface finishes—plain, indented, or helical rib—each wire is produced under strict quality control. Every batch undergoes rigorous testing to ensure compliance with GB/T, ASTM, and BS standards. Custom dimensions, tolerances, and finishes are available upon request.
