Specifications Introduction
Prestressed steel wire is a remarkable creation, meticulously engineered from the highest grade of high-carbon steel plates. The sophisticated process involves acid washing, cold drawing, or a stable treatment following phosphating. With state-of-the-art production techniques, it is classified into cold-drawing steel wire and stress-eliminating steel wire. By surface conditions, it encompasses plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire serves flawlessly in prestressed concrete post cold drawing, ensuring both reliability and exceptional performance.
Raw Material Requirements
At the core of prestressed concrete are top-caliber carbon steel wire rods, such as SWRH77B or SWRH82B. These wire rods must adhere to a comprehensive set of essential criteria, encompassing size, shape, weight and allowable deviation, grade and chemical composition, smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any specialized requirements. Meeting these stringent standards ensures optimal performance in application.
Cooling is expertly orchestrated using cutting-edge Sterem technology, achieving an impressive Sotenization rate that surpasses 85%. Typically, coils produced via these refined processes not only meet but often exceed the demanding production requirements for prestressed concrete steel wire and steel strand.
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 quintessential for the construction of single-story and multi-story homes, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It is also vital in modern high-rise buildings, underground constructions, hydraulic structures, marine installations, airport developments (such as runways and terminals), and nuclear power plant pressure vessels. This versatile steel wire is indispensable across industries, excelling in developments characterized by super-tall, super-span, super-volume, super-large area, and overweight load constructions, offering a wide range of shapes and structural engineering capabilities.
