Specifications Introduction
The Prestressed Steel Wire is a premium quality wire crafted meticulously from high-carbon steel plates. This wire undergoes processes like acid washing, cold drawing, or stabilization after phosphating, ensuring unparalleled quality and performance. Classified based on production technology, it includes cold-drawing steel wire and stress-eliminating steel wire. Additionally, its surface finishes can be categorized into plain, indented, and spiral ribbed. The cold drawing wire stands out as it is directly employed for prestressed concrete applications, ensuring durability and strength.
Raw Material Requirements
The core materials for our prestressed concrete solutions are top-tier carbon steel wire rods, specifically SWRH77B or SWRH82B. These wire rods meet stringent criteria for attributes such as size, shape, weight, and acceptable deviations. They adhere to high standards regarding grade and chemical composition, smelting methods, delivery conditions, mechanical properties, decarbonization layers, micro-structure, surface quality, and any special requirements needed to maintain integrity and performance.
Our cutting-edge Sterem technology meticulously controls cooling, achieving an impressive 85% Sotenization rate. This advanced process ensures that each coil consistently meets the rigorous production standards required for prestressed concrete steel wire and steel strand, guaranteeing reliability and excellence.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014 Steel wire for Prestressed Concrete 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
Prestressed steel wire lends its strength and flexibility to a diverse range of construction projects. From single-story to multi-story buildings, and infrastructures like highways, railways, bridges, electric poles, and pressure water pipes. Its applications extend to storage tanks, water towers, modern high-rise buildings, underground structures, hydraulic, marine, and airport facilities including runways and terminal buildings. It's indispensable in constructing pressure vessels for nuclear power plants and is pivotal across various industries handling super-tall, super-span, super-volume, super-large area, and overweight load structures, adapting to diverse shapes and functional engineering requirements.
