Specifications Introduction
Prestressed steel wire represents the pinnacle of excellence in steel wire technology, meticulously engineered from the highest quality high-carbon steel plates. This exquisite wire undergoes a rigorous process involving acid washing, advanced cold drawing, and a steady treatment post-phosphating. Utilizing cutting-edge production methods, this wire is classified into two main categories: cold-drawing steel wire and stress-eliminating steel wire. The surface conditions are key, offering variations such as plain, indentation, and spiral rib steel wire. This cold drawing wire is flawlessly integrated into prestressed concrete for post cold drawing applications, guaranteeing unmatched reliability and performance.
Raw Material Requirements
The cornerstone of premium prestressed concrete lies in the use of top-grade carbon steel wire rods like SWRH77B or SWRH82B. These rods must adhere to a stringent set of criteria, covering aspects such as size, shape, weight, and permissible deviation, as well as grade and chemical composition, smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any specific requirements. Meeting these rigorous standards ensures unparalleled performance in their applications.
Cooling is adeptly handled via the state-of-the-art Sterem technology, achieving an exceptional Sotenization rate of over 85%. Coils produced through these sophisticated processes consistently meet and often exceed the 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, ensuring global compliance and excellence.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete is vital for an array of construction marvels, including single-story and multi-story homes, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It also plays a crucial role in the construction of modern high-rise buildings, subterranean structures, hydraulic buildings, marine structures, airport developments (encompassing runways and terminals), and nuclear power plant pressure vessels. This versatile steel wire is indispensable across various industries, excelling in super-tall, super-span, super-volume, super-large area, and heavyweight load constructions, providing diverse shapes and structural engineering solutions.
