Specifications Introduction
Prestressed steel wire is a term used to describe steel wire crafted from top-quality high-carbon steel plates that undergo processes such as acid washing, cold drawing, or stabilization post-phosphating. Depending on production technology, it is categorized into cold-drawing steel wire and stress-eliminating steel wire. Surface variations allow classification into plain, indentation, and spiral rib steel wires. The cold drawing wire is specifically prepared for direct use in prestressed concrete, showcasing exceptional tensile strength and durability.
Raw Material Requirements
The fundamental raw components for prestressed concrete include premium carbon steel wire rods like SWRH77B or SWRH82B. Key specifications for wire rods involve adherence to size, shape, weight, permissible deviations, grade, chemical composition, and smelting methodology. The rods are also assessed based on delivery state, mechanical robustness, decarbonization layer, microstructure, surface integrity, and any specific custom requirements.
Cooling employs cutting-edge Sterem technology to ensure an impressive Sotenization rate exceeding 85%. This advanced process ensures that each coil meets the rigorous production standards of prestressed concrete steel wire and steel strand, promising unmatched quality and performance.
Standards of Steel Wire for Prestressed Concrete
Adhering to the prestigious GB/T5223-2014 standards 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 finds versatile applications across a diverse range of structures, including single-story and multi-story buildings, bridges for highways and railways, sleepers, electric poles, pressure water conduits, storage tanks, and water towers. Its adaptability extends to modern high-rise buildings, subterranean structures, and high-rise frameworks. It proves indispensable in hydraulic, marine, and airport constructions (runways and terminal buildings), as well as in the pressure vessels of nuclear power facilities. Its utility spans industries involving super-tall, super-span, super-volume, and super-large area projects, accommodating various structural engineering shapes and functions.
