Specifications Introduction
Prestressed steel wire represents a high-performance product meticulously manufactured from premium high-carbon steel plates. The process involves precise acid washing, cold drawing, or stable treatment following phosphating. Based on these technologically advanced production methods, prestressed steel wire is classified into cold-drawing steel wire and stress-eliminating steel wire. When considering surface conditions, options include plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire, renowned for its exceptional durability, is directly utilized in the formation of prestressed concrete following cold drawing, ensuring long-lasting structural integrity.
Raw Material Requirements
The backbone of prestressed concrete's remarkable strength lies in its raw materials, which are primarily high-quality carbon steel wire rods such as SWRH77B or SWRH82B. These rods must adhere to stringent criteria, including precise size, shape, weight, and allowable deviation. The requirements extend to the grade and chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, microstructure, and surface quality. Additionally, any special requirements are meticulously evaluated to ensure optimal performance and reliability.
The cooling process, executed with utmost precision using the advanced Sterem technology, achieves an astounding Sotenization rate of over 85%. This exceptional thermal management ensures that the coils produced through standard processes meet the rigorous production demands for prestressed concrete steel wire and steel strand, providing unparalleled strength and consistency.
Standards of Steel Wire for Prestressed Concrete
We adhere to the esteemed standards of GB/T5223-2014Prestressed concretesteel wire, in accordance withglobally recognized standards such as ASTM A421-16, ASTM A881/A881M-2005, BS5896-2012, EN10138-2:2009, GOST 7348-81,TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934-2, ABNT NBR 7482:2008,and more, ensuring unparalleled quality and international compatibility.
Applications for the Reinforcement of Concrete Constructions
Our steel wire for prestressed concrete is designed to meet diverse architectural and engineering needs. It is extensively used in single-story and multi-story houses, as well as highway and railway bridges, providing foundational support. Its applications extend to sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Our steel wire is integral to modern high-rise buildings, underground constructions, high-rise structures, hydraulic buildings, marine structures, and airport buildings, including runways and terminal buildings. Furthermore, it contributes to the strength and stability of pressure vessels in nuclear power plants. This versatile product is a staple in projects requiring super-tall, super-span, super-volume, super-large area, and heavy load applications, tailored to various shapes and structural functions across industries.
