Specifications Introduction
Prestressed steel wire stands as a pinnacle of engineering excellence, meticulously fashioned from premium high-carbon steel plates. This extraordinary material undergoes a sophisticated process of acid washing, cold drawing, or stable treatment post-phosphating. With cutting-edge production techniques, it is subdivided into cold-drawing steel wire and stress-eliminating steel wire categories. Depending on surface texture, it manifests as plain, indented, or spiral rib steel wire. The cold drawing variant excels in prestressed concrete post cold drawing, guaranteeing unmatched reliability and performance.
Raw Material Requirements
The bedrock of prestressed concrete is the superior quality carbon steel wire rods like SWRH77B or SWRH82B. These exceptional wire rods must adhere to rigorous standards, ensuring precise size, shape, weight, and allowable deviation. Additionally, they must meet stringent criteria in grade, chemical composition, smelting method, delivery condition, mechanical properties, and decarbonization layer, alongside a well-defined microstructure and surface quality. Meeting these high standards ensures unparalleled performance in diverse applications.
Cooling is expertly executed through Sterem technology, achieving an impressive Sotenization rate that surpasses 85%. Coils produced via these meticulous processes consistently meet and often exceed the rigorous demands for prestressed concrete steel wire and steel strand production.
Standards of Steel Wire for Prestressed Concrete
The acknowledged 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 for constructing single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It plays a pivotal role in erecting modern high-rise buildings, subterranean structures, hydraulic facilities, marine constructions, and airport infrastructures, including runways and terminals. Its versatility extends to nuclear power plant pressure vessels, making it indispensable across industries. This steel wire shines in super-tall, super-span, super-volume, super-large area, and overweight load structures, offering diverse forms and structural engineering capabilities.
