Specifications Introduction
The Prestressed Steel Wire we offer is a marvel of engineering excellence. Crafted from premium-grade high-carbon steel plates, this wire undergoes a meticulous process that includes acid washing, cold drawing, and a stable post-phosphating treatment. Utilizing cutting-edge production techniques, it is classified into two main categories: cold-drawing steel wire and stress-eliminating steel wire. Further differentiation based on surface conditions includes plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire is adeptly applied in prestressed concrete post cold drawing, ensuring supreme reliability and performance.
Raw Material Requirements
At the core of prestressed concrete lies the use of superior high-quality carbon steel wire rods, such as SWRH77B or SWRH82B. These wire rods are required to adhere to a plethora of stringent criteria—ranging from size, shape, weight, and allowable deviation to grade and chemical composition. Furthermore, they must conform to precise smelting methods, delivery conditions, mechanical properties, decarbonization layer, microstructure, surface quality, and any specialized demands. Meeting these rigorous standards ensures the pinnacle of performance in their applications.
Our Cooling Process utilizes the innovative Sterem technology, achieving an impressive Sotenization rate of over 85%. Typically, coils produced through these advanced standards not only meet but often exceed the production demands for prestressed concrete steel wire and steel strand, thereby ensuring consistent quality and performance.
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
Our Steel Wire for prestressed concrete is absolutely essential in reinforcing single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It's also crucial for modern high-rise buildings, subterranean structures, hydraulic facilities, marine constructions, as well as airport infrastructures like runways and terminals. Not to mention, its application extends to nuclear power plant pressure vessels. This versatile, high-strength steel wire underpins various industries, perfectly suited for super-tall, super-span, super-volume, super-large area, and overweight load constructions, while offering diverse structural engineering solutions.
