Specifications Introduction
Prestressed steel wire stands as a pinnacle of engineering excellence, meticulously fashioned from superior high-carbon steel plates. This impressive wire undergoes a rigorous process including acid washing, cold drawing, and stable treatment following phosphating. With state-of-the-art production techniques, it is divided into cold-drawing steel wire and stress-eliminating steel wire. Surface-wise, it encompasses plain steel wire, indentation steel wire, and spiral rib steel wire. Prestressed concrete benefits tremendously from the cold drawing wire post cold drawing, ensuring both robustness and unparalleled performance.
Raw Material Requirements
The very essence of prestressed concrete is rooted in the superior quality of carbon steel wire rods like SWRH77B or SWRH82B. These wire rods must adhere to a comprehensive set of criteria encompassing size, shape, weight, and allowable deviation, alongside grade and chemical composition, smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any special requirements. Adherence to these standards ensures peak performance in applications.
Cooling is skillfully controlled utilizing Sterem technology, securing a remarkable Sotenization rate above 85%. Coils produced through these rigorous processes consistently meet or even exceed 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
Steel wire for prestressed concrete emerges as an irreplaceable component in the construction of both single-story and multi-story residences, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. It plays a pivotal role in contemporary high-rise structures, underground frameworks, hydraulic constructions, marine edifices, airport buildings (including runways and terminals), and nuclear power plant pressure vessels. This adaptable steel wire finds its indispensable place across various industries, excelling in super-tall, super-span, super-volume, super-large area, and heavy-load constructions, offering an array of architectural and structural engineering solutions.
