Specifications Introduction
Prestressed steel wire is a distinguished category of steel wire, expertly crafted from superior high-carbon steel plates through advanced processes such as acid washing, cold drawing, or rigorous stabilization post-phosphating. This exceptional product can be classified into two primary types based on its production technology: the precision-engineered cold-drawing steel wire and the stress-eliminating steel wire. Furthermore, it showcases versatility in surface finishes, including plain steel wire, indentation steel wire, and spiral rib steel wire. Cold drawing wire is meticulously designed for direct application in prestressed concrete, ensuring unparalleled performance.
Raw Material Requirements
Prestressed concrete demands only the finest raw materials: primarily high-quality carbon steel wire rods such as SWRH77B or SWRH82B. These wire rods must conform to stringent standards encompassing size, shape, weight, and permissible deviations. Additionally, they are subjected to meticulous scrutiny for grade and chemical composition, smelting methods, delivery states, mechanical properties, decarbonization layers, micro-structure, surface quality, and fulfill any special requirements. This ensures unmatched quality and reliability in every application.
Cooling is precisely regulated through state-of-the-art Sterem technology, achieving an impressive over 85% Sotenization rate. Coils produced under these optimal conditions not only meet but often exceed the stringent production requirements for prestressed concrete steel wire and steel strand, ensuring excellence in every strand.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014 Prestressed concrete steel wire, according to ASTM 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, etc.
Applications for the Reinforcement of Concrete Constructions
The application of steel wire for prestressed concrete spans a vast array of structures and engineering marvels. From single-story to soaring multi-story edifices, and the robust highway and railway bridges to versatile sleepers and electric poles, its utility is unmatched. The wire fortifies pressure water pipes, storage tanks, and water towers, extending its reach to modern high-rise buildings, subterranean architecture, towering structures, hydraulic installations, and maritime constructions. It is integral to the infrastructure of airport buildings, including runways and terminals, and is critical to the safety and efficiency of pressure vessels in nuclear power plants. With applicability in various industries, it supports super-tall, super-span, super-volume, super-large area, and even overweight load structural engineering, in an exhaustive variety of shapes and functions.
