Specifications Introduction
Prestressed steel wire is an expertly engineered steel wire born from superior high-carbon steel plates, undergoing a sophisticated sequence of acid washing, cold drawing, or stable treatment following phosphating. This steel wire is categorized into cold-drawing steel wire and stress-eliminating steel wire, in accordance with its manufacturing techniques. It boasts remarkable versatility with variations such as plain steel wire, indentation steel wire, and spiral rib steel wire, depending on its surface texture. The cold drawing wire is efficiently deployed for prestressed concrete post cold drawing, offering a dependable solution for modern construction needs.
Raw Material Requirements
The foundational raw materials for prestressed concrete include premium-grade carbon steel wire rods like SWRH77B or SWRH82B. These wire rods must meet critical requirements, encompassing size, shape, weight, allowable deviations, grade, and chemical composition. The smelting method, delivery state, mechanical properties, decarbonization layer, microstructure, surface quality, and any specific requirements must also align with stringent standards to ensure exceptional performance.
Cooling is expertly regulated using advanced Sterem technology to accomplish an outstanding Sotenization rate surpassing 85%. Coils manufactured through standard methodologies typically fulfill the rigorous production needs for prestressed concrete steel wire and steel strand, ensuring high-quality outcomes for demanding applications.
Standards of Steel Wire for Prestressed Concrete
The prevailing 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,etc.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete finds extensive application across a spectrum of construction typologies including single-story and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its utility extends to contemporary high-rise edifices, subterranean structures, towering constructions, hydraulic installations, maritime frameworks, airport buildings, and the pressure vessels of nuclear power stations. This versatile steel wire caters to diverse sectors, facilitating architectural marvels with super-tall, super-span, super-volume, super-large area, and overweight load capabilities in various structural designs and functions.
