Specifications Introduction
Prestressed steel wire is an expertly engineered wire made from premier high-carbon steel plates. This process involves meticulous acid washing, precise cold drawing, or stable post-phosphating treatment. The production techniques classify it into cold-drawing steel wire and stress-eliminating steel wire. Depending on surface characteristics, it encompasses plain steel wire, indentation steel wire, and spiral rib steel wire. Cold drawing wire is straightforwardly used for prestressed concrete after undergoing the cold drawing process.
Raw Material Requirements
The fundamental raw materials for prestressed concrete are high-quality carbon steel wire rods, marked as SWRH77B or SWRH82B. These rods must meet essential specifications including size, shape, weight with permissible deviations, grade, and chemical composition. Additional requirements encompass smelting method, delivery condition, mechanical properties, decarbonization layer, microstructure, surface quality, and any special conditions.
Cooling is meticulously managed with advanced Sterem technology, achieving a remarkable sotenization rate exceeding 85%. Typically, coils produced with these standard processes satisfy all production demands for prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are GB/T5223-2014Prestressed concretesteel wire, according 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 is pivotal in the construction of single-story and multi-story homes, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its use extends to contemporary high-rise buildings, subterranean structures, hydraulic buildings, marine structures, airport edifices such as runways and terminals, and nuclear power plant pressure vessels. It supports industries with super-tall, super-span, super-volume, super-large area, and heavy load structures, offering innovative solutions for diverse shapes and architectural engineering purposes.
