Specifications Introduction
Meticulously crafted from premium high-carbon steel plates, our Helical PC Wire is the epitome of engineering excellence. Utilizing cutting-edge processes such as precision acid washing, advanced cold drawing, and sophisticated phosphating, we bring you a product that stands at the forefront of technological marvels. Available in two distinct forms—resilient cold-drawing steel wire and stress-relieving steel wire—it caters to a spectrum of applications with three exceptional surface finishes: plain for seamless integration, indented for superior bonding, and spiral ribbed for optimal frictional engagement. The cold-drawing variant emerges as the premier choice for enhancing the durability and robustness of prestressed concrete structures.
Raw Material Requirements
Our prestigious prestressed concrete wire is founded on the exceptional caliber of carbon steel wire rods like SWRH77B or SWRH82B. These rods are meticulously selected to adhere to stringent standards, ensuring precise sizing, impeccable shape, and exact weight tolerances. They exhibit high-grade chemical composition, exquisite smelting techniques, and ideal delivery conditions. The rods' outstanding mechanical properties, minimal decarbonization, and flawless surface quality are rigorously inspected to meet special requirements for unparalleled performance, reliability, and longevity.
Our innovative cooling process, empowered by the revolutionary Sterem technology, achieves a remarkable Sotenization rate exceeding 85%. This precision process ensures our coils consistently meet and surpass the stringent demands of prestressed concrete steel wire and strands, delivering unmatched consistency and superior quality every time.
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 expertly engineered to excel across a multitude of applications. It is indispensable in the construction of single and multi-story buildings, highway and railway bridges, resilient sleepers, electric poles, high-pressure water pipes, expansive storage tanks, and formidable water towers. Its adaptability extends to modern towering edifices, underground structures, vast hydraulic projects, intricate marine constructions, and cutting-edge airport facilities, including both runways and terminals. Designed for the most demanding industries that require super-tall, super-span, super-volume, and ultra-large area constructions, it is ideal for projects necessitating extraordinary loads, innovative shapes, and specialized functionalities in structural engineering.
