Specifications Introduction
The Prestressed Steel Wire stands as a marvel of engineering, meticulously crafted from premium high-carbon steel plates. With rigorous precision, it undergoes processes like acid washing, cold drawing, or stable post-phosphating treatment. This sophisticated production method classifies it into cold-drawing steel wire and stress-eliminating steel wire. Depending on the surface texture, it is available in plain steel wire, indentation steel wire, and spiral rib steel wire. Cold drawing wire is expertly applied in prestressed concrete post cold drawing, ensuring unparalleled reliability and robust performance.
Raw Material Requirements
The excellence of prestressed concrete is rooted in the exceptional quality of carbon steel wire rods like SWRH77B or SWRH82B. These wire rods are required to meet stringent criteria such as precise size, shape, weight with acceptable deviations, grade, chemical composition, smelting techniques, delivery conditions, mechanical properties, decarbonization layers, microstructure, and surface quality. These standards, along with any special stipulations, are meticulously upheld to ensure optimal performance in their applications.
Cooling is expertly managed using the advanced Sterem technology, achieving an impressive Sotenization rate of over 85%. Typically, coils produced through these stringent processes not only meet but often exceed the production demands for prestressed concrete steel wire and steel strand, ensuring superior quality and functionality.
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 key component for various structures, including single-story and multi-story residential buildings, highway and railway bridges, sleepers, electric poles, and pressure water pipes, as well as storage tanks and water towers. It proves essential in the development of contemporary high-rise edifices, subterranean structures, hydraulic buildings, marine structures, and airport constructions, from runways to terminals. Additionally, it is crucial in the creation of nuclear power plant pressure vessels. This versatile steel wire caters to a myriad of industries, playing a vital role in projects that demand super-tall, super-span, super-volume, super-large area, and heavyweight load constructions, offering limitless possibilities in shape and structural engineering.
