Specifications Introduction
Prestressed steel wire stands as a premium marvel of engineering, meticulously forged from high-grade high-carbon steel plates. Through a rigorous and sophisticated process involving acid washing, cold drawing, or stable treatment post-phosphating, this wire is born. With state-of-the-art production techniques, it is classified into two types: cold-drawing steel wire and stress-eliminating steel wire. Based on surface attributes, it is further divided into plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire is perfectly adapted for prestressed concrete post cold drawing, guaranteeing exceptional dependability and high performance.
Raw Material Requirements
The strength of prestressed concrete is founded on the superlative quality of carbon steel wire rods, such as SWRH77B or SWRH82B. These rods must adhere to stringent, multifaceted criteria, encompassing size, shape, weight, and permissible deviation, along with grade and chemical composition, smelting approach, delivery conditions, mechanical properties, decarbonization layer, microstructure, surface integrity, and any unique specifications. Adhering to these standards ensures superior performance and maximum efficiency in every application.
Cooling is meticulously controlled with Sterem technology, achieving an extraordinary Sotenization rate of over 85%. Coils crafted through these meticulous processes consistently meet and often exceed the production requirements for prestressed concrete steel wire and steel strand, ensuring unparalleled quality and reliability.
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 a cornerstone in enhancing the structural integrity of single-story and multi-story buildings, highway and railway overpasses, sleepers, electrical posts, pressure conduits, reservoirs, and water towers. It plays a critical role in the construction of contemporary skyscrapers, subterranean frameworks, hydraulic edifices, maritime structures, and airport facilities, including runways and terminals, as well as nuclear power plant pressure vessels. This adaptable steel wire supports a wide array of industries, carving out its essential position in super-tall, super-span, super-volume, super-large area, and super-heavy load constructions while offering a variety of shapes and structural engineering solutions.
