Specifications Introduction
Prestressed steel wire is a remarkable material, meticulously engineered from top-tier high-carbon steel plates. The production process is thorough, encompassing acid washing, cold drawing, or stable treatment post-phosphating. The advanced techniques used in its manufacture allow it to be classified into cold-drawing steel wire and stress-eliminating steel wire. Surface conditions further categorize it into plain, indentation, and spiral rib steel wires. Cold drawing wire is flawless for prestressed concrete post-processing, providing superior reliability and performance.
Raw Material Requirements
The core of prestressed concrete is the premium carbon steel wire rods, like SWRH77B or SWRH82B. These rods must meet stringent standards, including precise size, shape, weight, and allowable deviation; grade and chemical composition; smelting method; delivery condition; mechanical properties; decarbonization layer; microstructure; and surface quality, along with any special requirements. Meeting these standards ensures peak performance and reliability in various applications.
Cooling is expertly managed using state-of-the-art Sterem technology, achieving an impressive Sotenization rate of over 85%. Coils crafted through these refined processes consistently meet and often exceed the stringent production demands for prestressed concrete steel wire and steel strand.
Standards of Steel Wire for Prestressed Concrete
The recognized standards are GB/T5223-2014Prestressed concretesteel wire, conforming 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,and more.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete is crucial in the construction of single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. It is essential for modern high-rises, subterranean and hydraulic structures, marine structures, airport facilities, and nuclear plant pressure vessels. This adaptable steel wire finds its place in super-tall, super-span, super-volume, super-large area, and heavy load constructions, offering versatile design and structural engineering capabilities.
