SERH77B steel for prestressed steel wire strand

SERH77B is a high - quality high - carbon steel wire rod specifically designed for the manufacture of prestressed steel wires and strands. It features excellent strength, toughness, and weldability, and is widely used in the construction of infrastructure such as buildings, bridges, highways, and railways, providing strong support for modern engineering structures.

Advantages of SERH77B products

With advanced smelting and rolling processes, SERH77B has extremely high tensile strength and yield strength. It can withstand huge tensile forces, ensuring the stability and safety of prestressed concrete structures.

After special treatment, SERH77B has a very low stress relaxation rate. Even under long - term load, it can maintain a stable prestress, effectively preventing concrete cracking and extending the service life of the structure.

SERH77B not only has high strength but also good plasticity and toughness. It can withstand a certain degree of deformation without easy breakage, providing double - layer protection for engineering safety.

Using advanced surface treatment technology, SERH77B has a smooth surface, free of cracks and scars, which facilitates strand processing and subsequent construction operations.

Application cases of SERH77B steel for prestressed steel wires and strands

Bridge engineering: It is used in the prestressed concrete structures of various bridges such as suspension bridges, cable - stayed bridges, and arch bridges to improve the bearing capacity and seismic performance of bridges.

Highway engineering: It is used in the prestressed concrete pavements of highways and urban roads to extend the service life of the pavements and reduce maintenance costs.

Railway engineering: It is used in the prestressed concrete sleepers of high - speed railways and heavy - haul railways to improve the stability and safety of the tracks.

Water conservancy engineering: It is used in the prestressed concrete structures of water conservancy facilities such as dams, sluices, and aqueducts to enhance the impermeability and durability of the structures.

Building engineering: It is used in the prestressed concrete floor slabs, beams, and columns of high - rise buildings and large - span structures to improve the seismic performance and space utilization of buildings.

We strictly implement national standards and industry specifications to ensure that each batch of SERH77B undergoes strict quality inspections. The product is of reliable quality and worthy of trust.
