Specifications Introduction
Prestressed steel wire is an exceptional steel wire, masterfully crafted from the finest high-carbon steel plates through an exacting process that includes acid washing, cold drawing, or stable treatment post-phosphating. Based on the advanced production techniques, it is categorized into cold-drawing steel wire and stress-eliminating steel wire. Depending on surface conditions, it includes plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire is seamlessly utilized for prestressed concrete post cold drawing, ensuring reliability and performance.
Raw Material Requirements
The foundation of prestressed concrete lies in the high-quality carbon steel wire rods, such as SWRH77B or SWRH82B. These wire rods must meet a range of essential criteria, including 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. Ensuring these standards promises optimal performance in application.
Cooling is expertly managed using Sterem technology, achieving an outstanding Sotenization rate exceeding 85%. Typically, coils produced through these standard processes meet and often surpass the 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 is indispensable for single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It is also paramount for modern high-rise buildings, subterranean structures, hydraulic buildings, marine structures, airport constructions (including runways and terminals), and nuclear power plant pressure vessels. This versatile steel wire supports various industries, finding its niche in super-tall, super-span, super-volume, super-large area, and overweight load constructions, offering diverse shapes and structural engineering functions.
