Specifications Introduction
Prestressed steel wire is not just any steel wire; it is an exceptional material, meticulously engineered from premium high-carbon steel plates. This fine wire undergoes a rigorous process, including acid washing and cold drawing, or a stable treatment post-phosphating. These advanced production techniques segment it into cold-drawing steel wire and stress-eliminating steel wire. With varying surface conditions, it features plain, indentation, and spiral rib steel wire. The cold drawing wire excels in prestressed concrete post cold drawing, promising unmatched reliability and superior performance.
Raw Material Requirements
The cornerstone of prestressed concrete is the superior quality carbon steel wire rods, such as SWRH77B or SWRH82B. These rods must adhere to a comprehensive array of essential standards, including size, shape, weight, allowable deviation, grade, and chemical composition, along with smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any special requirements. Compliance with these standards ensures unparalleled performance in their applications.
Cooling is precisely controlled using the advanced Sterem technology, achieving an exceptional Sotenization rate of over 85%. Coils produced through these stringent processes consistently meet and often exceed the production demands 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 an essential component in the construction of single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It is crucial for modern high-rise buildings, subterranean structures, hydraulic buildings, marine structures, airport projects (including runways and terminals), and nuclear power plant pressure vessels. This adaptable steel wire supports a myriad of industries, offering its capabilities in super-tall, super-span, super-volume, super-large area, and overweight load constructions, providing diverse shapes and structural engineering solutions.
