Low-Relaxation Prestressing Steel Strand is a high-performance material used in prestressed concrete structures that demand long-term strength and stability. At DEJIA (Tianjin Dejia PC Steel Strand Co., Ltd.), we manufacture and supply premium-quality strands designed to meet the rigorous standards of modern construction and infrastructure projects. Our products are widely used in bridges, railways, highways, and large-scale buildings, ensuring lasting durability and structural integrity.
Our low-relaxation strands are engineered for superior mechanical stability under continuous load. The low-relaxation property minimizes stress loss, maintaining consistent tension and reliable long-term performance. With high tensile strength and excellent elongation, these strands perform exceptionally well in demanding applications such as bridges and high-rise structures.
Outstanding low-relaxation performance reduces long-term deformation.
High tensile strength and ductility for heavy-load applications.
Enhanced corrosion resistance for extended service life.
Uniform strand geometry for consistent stress distribution.
DEJIA produces a full range of prestressing strands in compliance with international standards including ASTM A416, BS 5896, and EN 10138. Available in multiple diameters and surface finishes, each strand undergoes strict inspection to ensure precise mechanical and dimensional performance.
| Parameter | Specification |
|---|---|
| Nominal Diameter | 9.3 mm – 18.0 mm |
| Tensile Strength Grades | 1860 MPa, 1960 MPa, 2000 MPa |
| Relaxation Class | Low Relaxation (≤2.5% at 1000 h, 70% UTS) |
| Surface Type | Plain, Indented, or Galvanized |
| Standard Compliance | ASTM, BS, EN, GB/T |
Our low-relaxation prestressing strands are ideal for bridge decks, railway sleepers, highway barriers, and large-span structures. They are also used in precast concrete components and post-tensioning systems where precision and long-term stability are essential.
Bridge and viaduct construction

Wind power and industrial foundations
As a certified National High-Tech Enterprise, DEJIA holds numerous patents and operates advanced production facilities covering 58,000 square meters. Our intelligent, eco-friendly manufacturing processes ensure consistent quality and efficiency. We have supplied materials for major national infrastructure projects, including bridges, railways, and wind power installations.
Our team provides customized solutions, technical expertise, and reliable delivery. With a strong international focus and compliance with global standards, DEJIA is a trusted partner for engineering and construction companies worldwide.
Each strand is securely packaged to prevent damage during transport. Coils are wrapped with moisture-resistant materials and placed on wooden pallets or steel reels for safe handling. Our quality assurance system includes rigorous inspection at every production stage, ensuring that all products meet mechanical and dimensional specifications. We coordinate logistics efficiently to ensure timely delivery for both domestic and international clients.
Selecting the right prestressing strand depends on project requirements such as load capacity, structural design, and environmental conditions. Factors like diameter, tensile grade, and surface finish should match the intended use. Our technical team is ready to help you choose the optimal low-relaxation PC strand for your project.
| Selection Factor | Recommendation |
|---|---|
| Project Type | Bridge, building, or precast element |
| Load Requirement | Select appropriate tensile strength grade |
| Exposure Environment | Use galvanized or indented surface for corrosion resistance |
