Specifications Introduction
Prestressed steel wire, a pinnacle of engineering excellence, is crafted from top-tier high-carbon steel plates. Through meticulous processes such as acid washing, cold drawing, and stabilization post-phosphating, it transforms into a versatile component. Categorized by production techniques, it emerges as either cold-drawing steel wire, known for its precision, or stress-eliminating steel wire, revered for durability. Surface-wise, it presents options like plain, indentation, or spiral rib steel wire. The cold drawing variant serves as a direct, reliable choice for prestressed concrete, showcasing its pivotal role in modern construction.
Raw Material Requirements
For the fabrication of prestressed concrete, the choice of raw materials is vital. High-quality carbon steel wire rods, specifically SWRH77B or SWRH82B, are paramount. These rods must adhere to stringent criteria including size, shape, weight, and permissible deviations to ensure excellence. Additionally, factors like grade, chemical composition, smelting methods, and delivery conditions are critical. Mechanical properties, decarbonization layers, micro-structure integrity, and surface quality are assessed to meet industry demands, alongside any bespoke specifications required for specialized applications.
Cooling is an art perfected through Sterem technology, ensuring an impressive Sotenization rate exceeding 85%. This advanced method guarantees that coils manufactured under standard procedures seamlessly meet the rigorous demands of prestressed concrete steel wire and strand production.
Standards of Steel Wire for Prestressed Concrete
The prevailing benchmarks guiding our steel wire quality are encapsulated in the GB/T5223-2014 standards. Prestressed concrete steel wire, according to We adhere to globally recognized standards including ASTM A421-16, ASTM A881/A881M -2005, BS5896-2012, EN10138-2:2009, and GOST 7348-81, as well as TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934 - 2, and ABNT NBR 7482:2008, among others.
Applications for the Reinforcement of Concrete Constructions
Steel wire for prestressed concrete serves an expansive range of applications. It fortifies structures from single-story homes to towering skyscrapers, supporting infrastructure like highway and railway bridges, and enhancing utility constructs such as electric poles and pressure water pipes. Its versatility extends to storage tanks and water towers, reflecting its indispensability in modern architecture. It is pivotal in sophisticated edifices including subterranean buildings, hydraulic and marine structures, and airport facilities like runways and terminals. It is integral to industries handling super-tall, super-span, super-volume, and super-large area projects, offering unparalleled support for demanding structural engineering feats.
