Specifications Introduction
Our prestressed steel wire stands as a pinnacle of engineering excellence, meticulously forged from the highest-grade high-carbon steel plates. Undergoing a rigorous process that includes acid washing, cold drawing, or post-phosphating treatments for stability, this steel wire is a testament to quality. Utilizing cutting-edge production methods, it is classified into cold-drawing steel wire and stress-eliminating steel wire. Depending on the surface specifics, options include plain steel wire, indentation steel wire, and spiral rib steel wire. The cold-drawn variant is flawlessly implemented for prestressed concrete post cold drawing, providing unmatched reliability and performance.
Raw Material Requirements
The cornerstone of our prestressed concrete solutions is the superior carbon steel wire rods, like SWRH77B or SWRH82B, which are meticulously selected to meet an array of vital standards. These standards encompass size, shape, weight, allowable deviation, grade, chemical composition, smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any specialized requirements. Adhering to these rigorous standards ensures peak performance and durability in every application.
Cooling precision is achieved through the groundbreaking Sterem technology, delivering an exemplary Sotenization rate that exceeds 85%. The coils crafted through this meticulous process consistently meet and often exceed the stringent production demands required for prestressed concrete steel wire and steel strand applications.
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 prestressed concrete steel wire is a vital component in the construction of single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its importance extends to contemporary high-rise structures, subterranean architecture, hydraulic edifices, marine installations, and comprehensive airport developments like runways and terminals. Additionally, it's indispensable in nuclear power plant pressure vessels. This versatile steel wire is a cornerstone across numerous industries, carving its niche in projects demanding super-tall, super-span, super-volume, super-large area constructions, and those requiring substantial load-bearing capabilities, while catering to diverse architectural designs and engineering specifications.
