Product Introduction
PC steel bar is a kind of low carbon alloy steel bar with heat treatment for high strength pre-stressed concrete pile. It is mainly used in producing port concrete pile, high-rise building foundation concrete pile and pier concrete pile, etc. It has undergone rigorous inspection, the material is superior, and the quality is up to standard.
Features
PC steel bar has high strength, toughness, low relaxation and good weldability. Its wire rod has good quality, low inclusion content and high purity. It has stable mechanical properties and is widely used in the construction of houses, bridges, roads and other projects. It is of high quality and is not easy to crack or rust, so you can use it with confidence.
