Specifications Introduction
Meticulously crafted from superior high-carbon steel plates, our Premium Helical PC Wire embodies engineering excellence through cutting-edge processes. These include precision acid washing, advanced cold drawing, and sophisticated phosphating, ensuring unparalleled quality. Available in two distinct varieties based on revolutionary production technology, choose the resilient cold-drawing steel wire for unmatched structural integrity or the stress-relieving steel wire for enhanced flexibility. Designed to cater to diverse applications, it offers three unique surface finishes: plain for seamless integration, indented for enhanced bonding, and spiral ribbed for optimal frictional engagement. The cold-drawing variant is the definitive choice for significantly bolstering the durability and robustness of prestressed concrete structures.
Raw Material Requirements
At the core of our premium prestressed concrete wire is the exceptional quality of carbon steel wire rods like SWRH77B or SWRH82B. Handpicked to meet rigorous standards, these rods guarantee precise size, impeccable shape, and exact weight tolerances. They possess a high-grade chemical composition, refined smelting techniques, and ideal delivery conditions. The rods' exceptional mechanical properties, minimal decarbonization, and impeccable surface quality are rigorously scrutinized, ensuring they meet special requirements for unparalleled performance and reliability.
Our innovative cooling process, driven by revolutionary Sterem technology, achieves an impressive Sotenization rate exceeding 85%. This precision ensures our coils consistently meet the rigorous demands of prestressed concrete steel wire and strands, delivering remarkable consistency and unmatched 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 to deliver exceptional performance across a multitude of applications. It plays pivotal roles in constructing single and multi-story buildings, highway and railway bridges, durable sleepers, electric poles, high-pressure water pipes, capacious storage tanks, and robust water towers. Its exceptional versatility extends to modern high-rise edifices, subterranean structures, expansive hydraulic projects, intricate maritime constructions, and state-of-the-art airport facilities, including runways and terminals. Designed specifically for industries demanding super-tall, super-span, super-volume, and ultra-large area constructions, it is the ideal choice for projects requiring extraordinary loads, unique shapes, and specialized functionalities in advanced structural engineering.
