Specifications Introduction
Prestressed steel wire is an extraordinary marvel of engineering, meticulously crafted from superior high-carbon steel plates. Through an intricate process involving precise acid washing, cold drawing, and stable treatment post-phosphating, this steel wire exemplifies excellence. Leveraging advanced production techniques, it is elegantly classified into cold-drawing steel wire and stress-eliminating steel wire. Determined by its surface conditions, it is also available in plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire is adeptly employed for prestressed concrete post cold drawing, guaranteeing both reliability and optimal performance.
Raw Material Requirements
The exceptional performance of prestressed concrete is rooted in the use of premium carbon steel wire rods, such as SWRH77B or SWRH82B. These rods are meticulously crafted to meet rigorous criteria, encompassing size, shape, weight, and allowable deviation, as well as grade and chemical composition. Further considerations include smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, and surface quality, alongside any special requirements. Adhering to these standards ensures peak performance in all applications.
Cooling is expertly administered using advanced Sterem technology, achieving a remarkable Sotenization rate over 85%. Typically, coils resulting from these refined processes consistently meet and often surpass the stringent production demands 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
Prestressed steel wire is critically important for reinforcing single and multi-story houses, highway and railway bridges, sleepers, electric poles, and pressure water pipes. Its utility extends to storage tanks, water towers, and stands as a cornerstone in modern high-rise buildings, subterranean structures, and hydraulic buildings. Additionally, it supports marine structures, airport constructions (including runways and terminals), and nuclear power plant pressure vessels. This adaptable steel wire is favored across multiple industries, proving indispensable in super-tall, super-span, super-volume, super-large area, and overweight load constructions, offering versatile shapes and structural engineering solutions.
