Specifications Introduction
Prestressed steel wire, an exceptional creation from premium-grade high-carbon steel plates, undergoes a refined process involving acid washing, meticulous cold drawing, or a stable post-phosphating treatment. Based on these production techniques, it is categorized into two distinct types: cold-drawing steel wire and stress-eliminating steel wire. Depending on their surface conditions, these wires can be further classified as plain steel wire, indentation steel wire, and spiral rib steel wire. Notably, cold drawing wire is directly utilized for the enhancement of prestressed concrete post cold drawing, offering superior performance and reliability in construction applications.
Raw Material Requirements
The essential raw materials for crafting prestressed concrete include superior carbon steel wire rods, specifically SWRH77B or SWRH82B. These wire rods must meet stringent criteria encompassing size, shape, weight and allowable deviation, grade and chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, microstructure, surface quality, and any bespoke requirements, etc. These parameters ensure that the final product retains an exceptional quality and performance, suitable for demanding construction needs.
The cooling process is meticulously managed using the advanced Sterem technology, achieving an exceptional Sotenization rate exceeding 85%. Typically, coils manufactured with these standard processes meet and often surpass production demands for prestressed concrete steel wire and steel strand, ensuring consistent quality and reliability in various construction applications.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014Prestressed concretesteel wire, according 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,etc.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete is extensively used across a wide array of constructions, including single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It extends its utility to state-of-the-art high-rise buildings, subterranean structures, towering edifices, hydraulic buildings, marine structures, airport infrastructures (runways and terminal buildings), and pressure vessels of nuclear power plants. Its superior strength and adaptability make it ideal for projects demanding super-tall, super-span, super-volume, super-large area, and overweight load, accommodating diverse shapes and advanced structural engineering demands.
