Specifications Introduction
Our prestressed steel wire is a marvel of engineering, expertly forged from top-tier high-carbon steel plates using a meticulous process that includes acid washing, cold drawing, and stable post-phosphating treatments. With state-of-the-art production techniques, it is classified into two categories: cold-drawing steel wire and stress-eliminating steel wire. Depending on surface conditions, it is available as plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire is integrated flawlessly into prestressed concrete post cold drawing, ensuring unmatched reliability and performance.
Raw Material Requirements
The core of prestressed concrete is high-quality carbon steel wire rods like SWRH77B or SWRH82B. These rods must adhere to a comprehensive set of criteria, including size, shape, weight, allowable deviation, grade, chemical composition, smelting method, delivery condition, mechanical attributes, decarbonization layer, microstructure, surface quality, and any special stipulations. Meeting these rigorous standards guarantees peak performance in every application.
Cooling is expertly controlled using cutting-edge Sterem technology, achieving an extraordinary Sotenization rate that exceeds 85%. Typically, coils manufactured through these standardized processes 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.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete is a cornerstone material for single-story and multi-story residences, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It is also vital for contemporary high-rise edifices, underground structures, hydraulic buildings, marine constructions, airport facilities (including runways and terminals), and nuclear power plant pressure vessels. This versatile steel wire caters to a broad spectrum of industries, making it indispensable in super-tall, super-span, super-volume, super-large area, and overweight load constructions, providing diverse structural forms and engineering uses.
