Specifications Introduction
Prestressed steel wire represents a pinnacle of engineering finesse, expertly forged from choice high-carbon steel plates. Through a meticulous process involving acid washing, cold drawing, or stable treatment post-phosphating, the steel wire is transformed into a high-performance material. Classified into cold-drawing steel wire and stress-eliminating steel wire, it boasts diverse surface finishes such as plain, indented, and spiral ribbed. The cold drawing wire's seamless integration into prestressed concrete ensures unmatched reliability and excellence in structural applications.
Raw Material Requirements
The cornerstone of prestressed concrete is embedded in superior high-carbon steel wire rods like SWRH77B or SWRH82B. These rods are rigorously evaluated on parameters such as dimensions, configuration, mass, and permissible deviations, alongside grade specifications and chemical composition. The smelting methodology, delivery conditions, mechanical attributes, decarbonization layer, microstructure, surface finish, and any specialized criteria must adhere to strict standards, ensuring peak performance and longevity in demanding applications.
Sterem technology precisely controls cooling, yielding an exemplary Sotenization rate of over 85%. Typically, coils fashioned through these meticulous processes not only meet but consistently exceed the stringent requirements for prestressed concrete steel wire and steel strand production.
Standards of Steel Wire for Prestressed Concrete
The recognized standards are GB/T5223-2014Prestressed concretesteel wire, conforming toASTM 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.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete is a critical component in the construction of single-story and multi-story residences, highway and railway overpasses, sleepers, electric poles, pressurized water infrastructure, storage tanks, and water towers. It plays a vital role in modern skyscrapers, subterranean constructs, hydraulic facilities, marine structures, airport developments (including runways and terminals), and nuclear power plant containment vessels. This adaptable steel wire is integral across various sectors, catering to super-tall, super-span, massive volume, extensive area, and heavyweight load structures, facilitating innovative architectural designs and engineering purposes.
