Specifications Introduction
Prestressed steel wire is meticulously engineered from the highest quality high-carbon steel plates. Through a rigorous process involving acid washing, cold drawing, and stable treatment post-phosphating, this steel wire achieves exceptional standards. Leveraging cutting-edge production techniques, it is classified into two types: 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 integrated into prestressed concrete post cold drawing, ensuring superior reliability and performance across applications.
Raw Material Requirements
The cornerstone of prestressed concrete is the premium quality of carbon steel wire rods, exemplified by SWRH77B or SWRH82B. These rods are required to meet a comprehensive set of criteria, including precise size, shape, weight, and permissible deviation, as well as deliverance of specific grade and chemical composition, smelting method, and mechanical properties. Furthermore, adherence to standards for decarbonization layer, microstructure, surface quality, and any special requirements is essential. Compliance with these rigorous standards ensures unmatched application performance.
Cooling is expertly handled using Sterem technology, achieving a remarkable Sotenization rate that exceeds 85%. Typically, coils produced through these meticulous processes not only meet but also surpass 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 is a vital component for various construction projects including single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its pivotal role extends to modern high-rise buildings, subterranean structures, hydraulic constructions, marine buildings, airport facilities such as runways and terminals, and nuclear power plant pressure vessels. This versatile steel wire is indispensable across numerous industries, adeptly supporting super-tall, super-span, super-volume, super-large area, and overweight load constructions, enhancing diverse shapes and structural engineering functions.
