Specifications Introduction
Prestressed steel wire stands as a remarkable innovation, forged from superior high-carbon steel plates through meticulous processes: acid washing, cold drawing, and stable treatment post-phosphating. This wire is elegantly divided into two types based on production methods: cold-drawing steel wire and stress-eliminating steel wire. Surface conditions further distinguish the wire into plain, indentation, and spiral rib varieties. The cold drawing wire is perfectly suited for prestressed concrete post cold drawing applications, promising exceptional reliability and performance.
Raw Material Requirements
The cornerstone of prestressed concrete is the premium quality carbon steel wire rods, such as SWRH77B or SWRH82B. These must adhere to stringent specifications including dimensions, shape, weight, and permissible deviation. Additional criteria encompass grade, chemical composition, smelting method, delivery status, mechanical properties, decarbonization layer, microstructure, surface quality, and any special requirements. Compliance with these standards ensures unparalleled performance in use.
Cooling excellence is achieved using pioneering Sterem technology, attaining an impressive Sotenization rate of over 85%. Coils crafted through these standardized methods consistently meet and frequently 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 crucial in construction, indispensable for single-story and multi-story buildings, highways, and railway bridges. It plays a pivotal role in sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. The wire is vital in modern high-rise structures, subterranean and hydraulic buildings, marine constructions, and airports (runways and terminals included), as well as nuclear power plant pressure vessels. This versatile steel wire caters to various industries, seamlessly integrated into super-tall, super-span, super-volume, super-large area, and overweight load constructions, offering a wide array of shapes and fulfilling diverse structural engineering purposes.
