Specifications Introduction
Our prestressed steel wire, an exemplary product of precision engineering, is meticulously crafted from the finest high-carbon steel plates. Through a transformative process of acid washing, cold drawing, or a stable post-phosphating treatment, we offer two main classifications: cold-drawing steel wire and stress-eliminating steel wire. Furthermore, based on surface conditions, we present a variety of wire types, including plain steel wire, indentation steel wire, and spiral rib steel wire. Our cold drawing wire is expertly designed for direct application in prestressed concrete, ensuring exceptional performance and reliability.
Raw Material Requirements
We insist on utilizing only superior carbon steel wire rods, primarily SWRH77B or SWRH82B, for our prestressed concrete applications. These wire rods must adhere to stringent criteria, encompassing dimensions, shape, weight, and permissible deviations. They also need to meet rigorous standards related to grade, chemical composition, smelting technique, delivery condition, mechanical properties, the decarbonization layer, microstructure, surface quality, and any additional special requirements essential for maintaining the highest quality standards.
Employing the revolutionary Sterem technology, we manage the cooling process with meticulous precision, achieving a remarkable Sotenization rate surpassing 85%. Our coils, produced following standardized procedures, meet and exceed the demanding requirements for prestressed concrete steel wire and steel strand production.
Standards of Steel Wire for Prestressed Concrete
Our steel wire proudly complies with the latest GB/T5223-2014 standards.Prestressed concretesteel wire, according toASTM A421-16, ASTM A881/A881M-2005, BS5896-2012, EN10138-2:2009, GOST 7348-81, reflecting international quality benchmarks.Also adhering to TU U27.3-136-004-2003, DSTU ISO 6934-2, GOST 7348-81, DSTU ISO 6934-2, and ABNT NBR 7482:2008, ensuring global compliance.etc.
Applications for the Reinforcement of Concrete Constructions
Our steel wire for prestressed concrete is incredibly versatile, serving a vast array of construction needs. It is ideal for single-story and multi-story houses, highway and railway bridges, sleepers, electric poles, pressure water pipes, storage tanks, and water towers. Its application extends to contemporary high-rise buildings, subterranean constructions, towering structures, hydraulic and marine edifices, airport infrastructure including runways and terminal buildings, and even the pressure vessels of nuclear power plants. It's a vital component across diverse industries involving super-tall, expansive, voluminous, and heavyweight constructions, as well as varied architectural and structural engineering projects.
