Specifications Introduction
Our Premium Helical PC Wire is crafted from the finest high-carbon steel plates, designed with precision and engineered using cutting-edge techniques. The journey begins with meticulous acid washing, followed by advanced cold drawing and sophisticated phosphating. This versatile steel wire is offered in two distinct varieties: the resilient cold-drawing steel wire and the stress-relieving version. Tailored for a multitude of applications, it features three innovative surface finishes: plain for seamless integration, indented for superior bonding, and spiral ribbed to maximize frictional engagement. The cold-drawing variant is an exceptional choice for enhancing the durability and strength of prestressed concrete structures.
Raw Material Requirements
The foundation of our premium prestressed concrete wire lies in the use of exemplary carbon steel wire rods such as SWRH77B or SWRH82B. Handpicked to adhere to stringent standards, these rods guarantee precise sizing, perfect shaping, and exact weight tolerances. They are characterized by a high-grade chemical composition, refined smelting techniques, and flawless delivery conditions. The superior mechanical properties, minimal decarbonization, and pristine surface quality of these rods are meticulously evaluated to ensure they meet special requirements, delivering exceptional performance and reliability.
Our innovative cooling process, powered by pioneering Sterem technology, achieves an outstanding Sotenization rate exceeding 85%. This precision ensures our coils consistently fulfill the demanding standards of prestressed concrete steel wire and strands, offering remarkable consistency and premium quality.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014Prestressed concretesteel wire, according 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,etc.
Applications for the Reinforcement of Concrete Constructions
Our steel wire for prestressed concrete is meticulously engineered for outstanding performance across a broad spectrum of applications. It is indispensable in the construction of single and multi-story buildings, highway and railway bridges, robust sleepers, electric poles, high-pressure water pipes, large storage tanks, and sturdy water towers. Its adaptability further extends to modern high-rise buildings, subterranean structures, vast hydraulic projects, intricate maritime constructions, and cutting-edge airport facilities, including runways and terminals. Crafted for industries demanding super-tall, super-span, super-volume, and ultra-large area constructions, it excels in projects requiring extraordinary loads, unique architectural shapes, and specialized functionalities in structural engineering.
