In modern infrastructure construction, structural stability and long-term durability are essential engineering requirements. As a vital reinforced building material, prestressed steel strand is widely utilized in bridges, highways, water conservancy facilities, municipal works and large-scale construction projects. Manufactured by Anhui Litong Rare Earth Steel Cable Co., Ltd., our prestressed steel strand features high tensile strength, low relaxation rate and stable mechanical properties, serving as a trustworthy choice for engineering contractors at home and abroad.
1. Outstanding Product Performance
Made of premium high-carbon steel materials, our prestressed steel strand adopts mature stabilization treatment technology. It boasts a compact stranded structure, smooth surface, precise dimensional tolerance and excellent straightness. The ultra-high tensile strength can effectively offset the internal tensile stress of concrete, reduce structural cracks and improve overall bearing capacity. Furthermore, its low relaxation performance minimizes stress loss during long-term service, permanently maintaining the stability of engineering structures.

2. Versatile Application Range
With superior mechanical performance, Litong’s prestressed steel strands adapt to various complex and harsh construction environments. They are commonly applied in bridge engineering for box girders and reinforcement structures to enhance spanning capacity. In water conservancy projects, the strands effectively prevent deformation of dams and reservoirs. Besides, they are widely used in high-rise buildings, underground garages, highway roadbeds, railway sleepers and tunnel support systems, providing solid structural guarantee for diversified infrastructure construction.
