Specifications Introduction
Prestressed steel wire is an umbrella term for steel wire crafted from high-quality high-carbon steel plates, undergoing processes like acid washing, cold drawing, or stabilized treatment post-phosphating. Depending on the production technology, it bifurcates into cold-drawing steel wire and stress-eliminating steel wire. Based on surface conditions, it is categorized into plain steel wire, indentation steel wire, and spiral rib steel wire. Cold drawing wire is directly utilized for prestressed concrete post the cold drawing process.
Raw Material Requirements
The core raw materials for prestressed concrete consist of high-quality carbon steel wire rods, specifically SWRH77B or SWRH82B. Key wire rod requirements include 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 is meticulously controlled by Sterem technology, achieving an impressive over 85% Sotenization rate. Typically, coils produced through standard processes fulfill the demanding production requirements for prestressed concrete steel wire and steel strands.
Standards of Steel Wire for Prestressed Concrete
The prevailing standards are defined by 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
The diverse applications of steel wire for prestressed concrete extend widely across single-story and multi-story residences, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It also finds significant use in modern high-rise buildings, subterranean structures, high structures, hydraulic buildings, marine structures, airport facilities (runways and terminal buildings), and nuclear power plant pressure vessels. These wires meet the rigorous demands of numerous industries, accommodating super-tall, super-span, super-volume, super-large area constructions, and overweight load-bearing projects across various structural engineering disciplines with diverse shapes and functions.
