Specifications Introduction
Prestressed steel wire stands as an extraordinary product of engineering excellence, meticulously fashioned from superior high-carbon steel plates. This marvel is brought to life through a rigorous process that encompasses acid washing, precise cold drawing, or a stable treatment following phosphating. Further honing its superior quality, it is classified into cold-drawing steel wire and stress-eliminating steel wire. On the basis of surface conditions, the range includes plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire is flawlessly integrated into prestressed concrete post cold drawing, guaranteeing unmatched reliability and peak performance.
Raw Material Requirements
The cornerstone of high-performance prestressed concrete lies in premium carbon steel wire rods, exemplified by SWRH77B or SWRH82B. These wire rods must adhere to a comprehensive set of vital standards, covering size, shape, weight and allowable deviation, grade and chemical composition, smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any special requirements. Adhering to these exacting standards ensures optimal functionality and performance in practical applications.
Cooling is masterfully executed through Sterem technology, achieving an exceptional Sotenization rate that exceeds a remarkable 85%. Coils produced using these stringent processes consistently meet and often surpass 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 a critical component for both single-story and multi-story houses, as well as expansive highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its pivotal role extends to modern high-rise wonders, subterranean fortresses, hydraulic structures, marine edifices, airport infrastructures (encompassing runways and terminals), and nuclear power plant pressure vessels. This versatile steel wire is indispensable across numerous industries, excelling in super-tall, super-span, super-volume, super-large area, and overweight load constructions, while offering a myriad of shapes and structural engineering functions.
