Specifications Introduction
Prestressed steel wire is a meticulously engineered product, derived from superior high-carbon steel plates. This specialized wire undergoes a precise process involving acid washing, cold drawing, or stable treatment post-phosphating. The production methodology classifies it into cold-drawing steel wire and stress-eliminating steel wire. Furthermore, based on surface conditions, it is categorized as plain steel wire, indentation steel wire, and spiral rib steel wire. Cold drawing wire is directly employed in prestressed concrete after the cold drawing process.
Raw Material Requirements
Prestressed concrete primarily demands the use of high-quality carbon steel wire rods like SWRH77B or SWRH82B. These wire rods must adhere to strict criteria including size, shape, weight, and allowable deviation, as well as grade and chemical composition. Additional considerations include smelting method, delivery state, mechanical properties, decarbonization layer, microstructure, and surface quality, along with any special requirements that may be needed.
Through the implementation of advanced Sterem technology, cooling is exceptionally controlled to achieve an astounding Sotenization rate exceeding 85%. Standard process coils typically fulfill the rigorous production demands for prestressed concrete steel wire and steel strand, ensuring excellence and consistency.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are GB/T5223-2014Prestressed concretesteel wire, according 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,etc.
Applications for the Reinforcement of Concrete Constructions
The steel wire for prestressed concrete is integral to the construction of single-story and multi-story homes, highway and railway bridges, sleepers, and electrical poles. Its usage extends to pressure water pipes, storage tanks, and water towers. Significantly, it plays a crucial role in the development of modern high-rise buildings, subterranean structures, and towering edifices. Its applications span hydraulic constructions, marine structures, airport buildings including runways and terminal complexes, as well as the pressure vessels of nuclear power plants. Furthermore, it’s utilized in various sectors for projects that require super-tall, super-spanning, or super-volume structures, accommodating diverse shapes and structural engineering functions.
