Specifications Introduction
Prestressed steel wire is a remarkable engineering marvel, meticulously forged from premium high-carbon steel plates. This product undergoes a sophisticated process involving acid washing, precision cold drawing, and stable treatment post-phosphating. Utilizing cutting-edge production techniques, it is distinguished into two primary categories: cold-drawing steel wire and stress-eliminating steel wire. Furthermore, based on the surface texture, it boasts variants such as plain steel wire, indentation steel wire, and spiral rib steel wire. The cold drawing wire is seamlessly integrated into prestressed concrete post cold drawing, delivering unmatched reliability and exceptional performance.
Raw Material Requirements
The excellence of prestressed concrete is rooted in the superior quality of carbon steel wire rods like SWRH77B or SWRH82B. These wire rods adhere to stringent criteria, encompassing size, shape, weight, and permissible deviation, along with grade and chemical composition. Additionally, factors such as smelting method, delivery condition, mechanical properties, decarbonization layer, and microstructure are meticulously observed. Surface quality and specific requirements are also paramount. Adhering to these standards ensures optimal performance in its applications.
Cooling is expertly executed using Sterem technology, achieving an impressive Sotenization rate exceeding 85%. Coils produced through these standardized processes consistently meet and surpass the rigorous demands for prestressed concrete steel wire and steel strand production.
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 absolutely vital across a multitude of construction landscapes. It is indispensable for the reinforcement of single-story and multi-story houses, expansive highway and railway bridges, railway sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Moreover, its significance extends to cutting-edge high-rise buildings, subterranean structures, hydraulic edifices, marine architectures, and airport constructions, including runways and terminals. Additionally, it plays a critical role in nuclear power plant pressure vessels. This versatile steel wire supports a wide array of industries, carving its niche in super-tall, super-span, super-volume, super-large area, and overweight load constructions, offering an array of shapes and structural engineering functions.
