Specifications Introduction
Immerse yourself in the world of our prestressed steel wire, an epitome of engineering excellence crafted from high-quality high-carbon steel plates. Experience the meticulous art of its creation, which involves acid washing, sophisticated cold drawing, and post-phosphating stabilization. This process births two distinct marvels: the cold-drawing steel wire and the stress-eliminating steel wire. Furthermore, based on the surface finish, our wire diversifies into plain, indentation, and spiral rib varieties. The cold drawing wire, in particular, is a direct hero in fortifying prestressed concrete.
Raw Material Requirements
Our prestressed concrete steel wire is born from the finest High-quality carbon steel wire rods, specifically SWRH77B or SWRH82B. These rods are rigorously assessed based on size, shape, weight, and permissible deviations. They are further scrutinized for grade, chemical composition, smelting method, delivery state, mechanical properties, decarbonization layer, micro-structure, and surface quality. We also consider any special requirements, ensuring impeccable quality and performance.
Embrace the precision of Sterem technology in our cooling process, achieving an impressive over 85% Sotenization rate. This cutting-edge approach ensures that coils produced meet the stringent demands of prestressed concrete steel wire and steel strand production, consistently delivering excellence.
Standards of Steel Wire for Prestressed Concrete
Adhering to the latest standards, 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
Our steel wire for prestressed concrete is a cornerstone in civil engineering, enhancing the structural integrity of single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, and pressure water pipes. It is indispensable in constructing storage tanks, water towers, and has expanded its legacy into modern high-rise buildings, underground facilities, and high-rise structures. Discover its vital role in hydraulic buildings, marine structures, and airport infrastructures, including runways and terminal buildings. It is trusted for pressure vessels of nuclear power plants and more, across various industries, adeptly supporting super-tall, super-span, super-volume, super-large area, and overweight load projects in diverse structural forms and functionalities.
