China High Quality Wholesale 30mnsi Wire Rod for Prestressed Concrete Steel

ZHENGDE Prestressed steel wire is a high-strength steel, widely used in construction, bridges, tunnels, water conservancy projects and other fields. It has excellent mechanical properties and durability, and can effectively improve the bearing capacity and seismic performance of structures.
The material of the prestressed steel wire is mainly high-strength steel wire, and steel wires such as SWRH82B and SWRH77B are usually used. These steel wires have the characteristics of high strength, high toughness, high durability, etc., can withstand large tensile and bending forces, and also have good corrosion resistance and fatigue resistance.
The manufacturing process of prestressed steel wire mainly includes drawing, steel wire stranding, prestressing processing and other links. During the drawing process, the steel wire is drawn and annealed multiple times to make it meet the requirements of high strength and high toughness. In the wire stranding process, multiple steel wires are twisted into one prestressed steel wire to improve its bearing capacity and seismic performance. During the prestressing process, the prestressed steel wire is tensioned to a certain level of prestressing, so that it generates compressive stress in the structure, thereby improving the bearing capacity and seismic performance of the structure.
