Specifications Introduction
Prestressed steel wire is an outstandingly engineered steel wire, meticulously crafted from premium high-carbon steel plates. The production process includes precise acid washing, cold drawing, or stable treatment following phosphating. Leveraging state-of-the-art production techniques, it is divided into cold-drawing steel wire and stress-eliminating steel wire. Depending on the surface finish, it includes plain steel wire, indentation steel wire, and spiral rib steel wire. This cold-drawing wire is seamlessly integrated into prestressed concrete applications, ensuring unparalleled reliability and performance.
Raw Material Requirements
The quality of prestressed concrete is anchored in superior carbon steel wire rods like SWRH77B or SWRH82B. These rods must adhere to stringent criteria, encompassing dimensions, shape, weight, permissible deviation, grade, and chemical composition. Additionally, they must meet specifications for smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, and surface quality. Meeting these criteria guarantees optimal performance in every application.
The cooling process is adeptly managed using Sterem technology, achieving a remarkable Sotenization rate exceeding 85%. Coils produced through these rigorous standard processes consistently fulfill and often surpass the demanding requirements for prestressed concrete steel wire and steel strand production.
Standards of Steel Wire for Prestressed Concrete
The accredited 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 vital for a wide range of structural applications, including single-story and multi-story residences, highway and railway bridges, sleepers, electric poles, pressurized water pipelines, storage tanks, and water towers. It is also crucial for modern high-rise structures, subterranean frameworks, hydraulic buildings, marine structures, airport terminals and runways, and nuclear power plant pressure vessels. This versatile steel wire is essential across diverse industries, excelling in super-tall, super-span, super-volume, super-large area, and heavyweight constructions, offering varied shapes and innovative structural engineering solutions.
