Specifications Introduction
Expertly crafted from top-grade high-carbon steel plates, our Premium Helical PC Wire is a testament to superior engineering, featuring cutting-edge processes such as precision acid washing, advanced cold drawing, and nuanced phosphating. This adaptable product comes in two exceptional forms based on production technology: the durable cold-drawing steel wire and the stress-relieving steel wire. Designed for a myriad of applications, it boasts three distinctive surface finishes: plain for smooth application, indented for enhanced bonding properties, and spiral ribbed for maximum frictional engagement. The cold-drawing variant stands as the premier choice for reinforcing the endurance and strength of prestressed concrete structures.
Raw Material Requirements
Our elite prestressed concrete wire is founded on the outstanding quality of carbon steel wire rods like SWRH77B or SWRH82B. These rods are rigorously selected to meet stringent standards, ensuring accurate size, flawless shape, and precise weight tolerances. They feature exemplary chemical composition, refined smelting processes, and optimal delivery conditions. The rods' superior mechanical properties, negligible decarbonization, and impeccable surface quality are meticulously evaluated to ensure they meet special requirements for exceptional performance and reliability.
Our groundbreaking cooling process, spearheaded by advanced Sterem technology, achieves an extraordinary Sotenization rate surpassing 85%. This precision guarantees our coils consistently meet the demanding standards of prestressed concrete steel wire and strands, ensuring remarkable uniformity and unmatched quality.
Standards of Steel Wire for Prestressed Concrete
The current standards are GB/T5223-2014Prestressed concretesteel wire, as outlined inASTM 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 expertly engineered to deliver exceptional performance across a wide array of applications. It plays a crucial role in constructing both single and multi-story buildings, highway and railway bridges, resilient sleepers, electric poles, high-pressure water pipes, expansive storage tanks, and sturdy water towers. Its versatility reaches into modern high-rise buildings, underground structures, massive hydraulic projects, complex maritime constructions, and cutting-edge airport facilities, including runways and terminals. Perfectly designed for industries that demand super-tall, super-span, super-volume, and ultra-large area constructions, it is the ideal choice for projects that require extraordinary loads, unique shapes, and specialized functionalities in structural engineering.
