Specifications Introduction
Prestressed steel wire stands as an extraordinary marvel in steel craftsmanship. Expertly forged from the highest-quality high-carbon steel plates, it undergoes a meticulous process encompassing acid washing, cold drawing, and stable treatment after phosphating. With cutting-edge production techniques, it is classified into two distinct types: cold-drawing steel wire and stress-eliminating steel wire. Depending on the surface condition, it diversifies into plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire, renowned for its precision, is optimally employed for prestressed concrete post cold drawing, offering unmatched reliability and superior performance.
Raw Material Requirements
The excellence of prestressed concrete is rooted in the superior quality of the high-carbon steel wire rods used, such as SWRH77B or SWRH82B. These wire rods are required to meet a comprehensive set of essential criteria including size, shape, weight and allowable deviation, grade and chemical composition, smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any special requirements. Adhering to these rigorous standards guarantees optimal performance and reliability in diverse applications.
Cooling is precisely managed through state-of-the-art Sterem technology, achieving an exceptional Sotenization rate of over 85%. Coils produced through these high-standard processes consistently meet and often exceed production requirements for prestressed concrete steel wire and steel strand, ensuring superior durability and strength.
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 vital for enhancing the structural integrity of single-story and multi-story homes, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. It is equally crucial for cutting-edge high-rise buildings, subterranean structures, hydraulic buildings, marine structures, airport constructions including runways and terminals, and nuclear power plant pressure vessels. This versatile steel wire plays a transformative role across numerous industries, ideal for super-tall, super-span, super-volume, super-large area, and heavyweight load constructions, providing diverse shapes and innovative structural engineering solutions.
