Specifications Introduction
The term 'prestressed steel wire' epitomizes a category of steel wire crafted from superior high-carbon steel plates that undergo meticulous processes like acid washing, cold drawing, or stabilization post-phosphating. These wires are expertly classified based on distinct production methods into cold-drawing steel wire and stress-eliminating steel wire. Furthermore, their surface characteristics allow for their division into plain steel wire, indentation steel wire, and spiral rib steel wire. Among these, cold drawing wire stands out as it is directly employed in the construction of prestressed concrete, showcasing its unique capability and reliability.
Raw Material Requirements
The quintessential raw materials that fortify prestressed concrete are premium carbon steel wire rods such as SWRH77B or SWRH82B. These wire rods must adhere to stringent specifications concerning size, shape, weight, and allowable deviation. Their grade and chemical composition are critically assessed, alongside their smelting method, delivery condition, mechanical properties, decarbonization level, microstructure, and surface quality. Special requirements are diligently considered to ensure the material's unparalleled strength and performance.
Harnessing advanced Sterem technology, the cooling process is meticulously controlled to achieve an impressive over 85% Sotenization rate. The coils manufactured under this streamlined process effortlessly meet the demanding standards required for producing prestressed concrete steel wire and steel strands, assuring unmatched quality and consistency.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014 Prestressed concrete steel wire, according to ASTM 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 is a cornerstone in the reinforcement of various architectural marvels, including single and multi-story houses, and critical infrastructure such as highway and railway bridges, sleepers, and electric poles. Their utility extends to pressure water pipes, storage tanks, and water towers. In modern contexts, they find application in towering skyscrapers, subterranean constructions, expansive high-rise structures, hydraulic facilities, marine architecture, and airport buildings (runways and terminal buildings). They are also integral in pressure vessels for nuclear power plants. This steel wire serves diverse industries, especially in projects characterized by exceptional height, extensive span, massive volume, expansive area, and heavy load, enhancing structural integrity across various designs and functionalities.
