Specifications Introduction
Prestressed steel wire represents a category of high-quality high-carbon steel wires, meticulously crafted through processes like acid washing, cold drawing, or post-phosphating stabilization. Based on production techniques, it is classified into cold-drawing steel wire and stress-eliminating steel wire. Furthermore, surface conditions yield plain, indented, and spiral rib steel wires. Cold drawing wire is directly utilized for prestressed concrete applications post the cold-drawing process.
Raw Material Requirements
The foundational materials for prestressed concrete are premium carbon steel wire rods, specifically SWRH77B or SWRH82B. These wire rods must meet stringent criteria encompassing size, shape, weight, allowable deviation, grade, chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, micro-structure, surface quality, and any special requirements.
Cooling processes utilize advanced Sterem technology, boasting an impressive over 85% Sotenization rate. Wire coils produced through this method perfectly align with the stringent requirements for prestressed concrete steel wire and steel strands.
Standards of Steel Wire for Prestressed Concrete
The steel wires adhere to the rigorous standards specified in 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 wires for prestressed concrete find extensive applications in the reinforcement of single-story and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. They are integral to modern high-rise buildings, underground constructions, high-rise structures, hydraulic buildings, marine structures, airport buildings (including runways and terminal buildings), and nuclear power plant pressure vessels. They support various industries, catering to projects involving super-tall, super-span, super-volume, super-large area, and heavyweight load in diverse architectural forms and functioning structural engineering.
