Specifications Introduction
Prestressed steel wire is a general term for steel wire made of high-quality high-carbon steel plates after acid washing, cold drawing, or stable treatment after phosphating. According to the different production technologies, it can be divided into two types: cold-drawing steel wire and stress-eliminating steel wire. According to the different surface conditions, it can be divided into plain steel wire, indentation steel wire, and spiral rib steel wire. Cold drawing wire is a steel wire directly used for prestressed concrete after cold drawing.
Raw Material Requirements
The main raw materials for prestressed concrete are High-quality carbon steel wire rods of SWRH77B or SWRH82B, the main requirements for the wire rods are size, shape, weight and allowable deviation, grade and chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, micro-structure, surface quality, and special requirements, etc.
Cooling is controlled by Sterem technology which is used to achieve over 85% Sotenization rate. Generally, the coil produced according to the normal process can meet the production requirements of prestressed concrete steel wire and steel strand.
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
The application of steel wire for prestressed concrete consists of single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Expand to modern high-rise buildings, underground buildings, high-rise structures, hydraulic buildings, marine structures, airport buildings(runways and terminal buildings), pressure vessels of nuclear power plants, etc...Various industries, such as super-tall, super-span, super-volume,super-large area, and overweight load, In various shapes and different functions of structural engineering.
