Product Introduction
High Strength Prestressed Steel Strand is one of the most important products in our enterprise. It has a wide range of uses, not only in the construction of high-end concrete structures such as railways, highways, bridges, nuclear power plants and large-span buildings, but also in industries such as storage rack manufacturing, lifting machinery manufacturing, and wind power equipment manufacturing.
Features
High Strength Prestressed Steel Strand has a unique manufacturing process, using cold-rolled and hot-drawn production technology to complete the fusion between metals. Due to high-quality materials and high-tech processing, it will not appear disjointed, peeled, and cracked. Moreover, it has a thick surface metal layer, strong corrosion resistance and long service life. Its connection process is safe and reliable, the joint is firm and the stability is good. It has strong functionality, and the surface metal has good electrical conductivity.
