Product Overview
9.53mm 12.7mm 15.2mm Prestressed Concrete Low Relaxation 1860MPA 7 Wire PC Steel Strands ASTM A416 Grade 270 PC Steel Strand
Prestressed steel strand is a metal wire made up of multiple high-strength steel wires twisted together. By applying tensile stress in advance before the construction of concrete structures, it offsets the compressive stress generated during the use of the structure, thereby improving the crack resistance, stiffness, and bearing capacity of the components. It is the core load-bearing material of prestressed concrete structures, widely used in engineering fields such as bridges, buildings, and water conservancy.

Product Advantages
- High strength: The tensile strength can reach 3-4 times that of ordinary steel, which can significantly reduce the amount of structural reinforcement and reduce self weight.
- Low relaxation: After long-term stress, the stress loss is small, ensuring the durability of the prestressing effect.
- Good flexibility: Easy to transport and install, suitable for complex structural shapes.
- Corrosion resistance: Through galvanizing, epoxy coating and other treatments, it can be used for a long time in harsh environments such as humidity and salt alkali.
Product Applications
- Bridge engineering: The box girder, cable-stayed cables, and main suspension cables of large-span bridges are used to enhance the bridge's crossing capacity and durability.
- Construction engineering: Floors, beams, prestressed floors of high-rise buildings, as well as roof truss structures of large venues and factories.
- Water conservancy engineering: Pressure pipelines of dams, aqueducts, hydropower stations, etc., which resist stress caused by water pressure and structural self weight.
- Geotechnical engineering: Slope reinforcement, foundation pit support, mine roadway support, etc., to enhance the stability of rock and soil mass.
