Retard-bonded PC Strand 28.6 1570

Retard-bonded PC Strand is a high-performance prestressed concrete strand designed for use in construction projects that require superior strength, durability, and long-term stability. This product, specifically available in the 28.6mm diameter and 1570MPa tensile strength configuration, is engineered to meet the rigorous demands of modern infrastructure development. The term "retard bonded" refers to a specialized coating or treatment applied to the strand that delays the bond between the steel and surrounding concrete, allowing for more controlled stress distribution during the curing process. This feature makes it particularly suitable for applications where precise load transfer and structural integrity are essential.

The Retard-bonded 28.6 1570 PC Strand is manufactured using advanced cold-drawn technology, ensuring consistent quality and performance across all units. Its unique composition allows for enhanced corrosion resistance, making it ideal for use in environments exposed to moisture, chemicals, or aggressive weather conditions. The 28.6mm size is one of the most commonly used diameters in precast and prestressed concrete elements, offering a balance between strength and ease of handling. The 1570MPa tensile strength rating ensures that the strand can withstand high levels of stress without compromising its structural properties.
