Product Description

Steel Wire Rope Pc Strand 1*7 15.24mm Post Tension Steel Strand 1860

Prestressing Steel Strand for Bridge

 

Product Introduction

 

This product is a 1 × 7 high-strength prestressed steel strand, made of SWRH82B high carbon

steel wire rod as raw material, and processed through drawing, twisting, low-temperature

stabilization, and other processes. The nominal diameter is 15.2mm, the tensile strength

is ≥ 1860MPa, the yield strength is ≥ 1670MPa, and the maximum total elongation rate

is ≥ 3.5%. All indicators comply with the GB/T 5224-2014 standard.

Product Advantages

High strength and low relaxation performance: SWRH82B high carbon steel wire rod is used,

with a tensile strength of ≥ 1860MPa and an initial relaxation rate of ≤ 2.5%. The long-term

stress loss is only one-third of that of ordinary products, ensuring the long-term mechanical

stability of the structure


Standardized adaptation performance: Strictly following the GB/T 5224-2014 standard for

production, with nominal diameter tolerance controlled within ± 0.05mm, it can seamlessly

match mainstream anchoring systems such as OVM, VM, PESM at home and abroad, reducing

construction adaptation costs


Uniform mechanical properties: Through online stress relief technology, the maximum force total

elongation deviation of the same batch of steel strands is ≤ 0.5%, and the tension process is

uniformly stressed to avoid structural damage caused by local stress concentration

 

Product Application

 

At present, it has been widely used in engineering scenarios such as large-span bridge box girders,

nuclear power plant safety shells, prestressed anchoring of water conservancy dam bodies,

and splicing of subway shield tunnel segments, providing reliable mechanical guarantees for the

long-term safe service of structures.
