Specifications Introduction
Crafted from the finest high-carbon steel plates, our Durable Helical PC Wire is masterfully engineered using cutting-edge processes, which include precision acid washing, advanced cold drawing, and sophisticated phosphating. This versatile innovation is offered in two distinct varieties determined by production technology: the resilient cold-drawing steel wire and the stress-relieving steel wire. Designed to cater to a broad range of applications, it comes in three unique surface finishes: plain for seamless integration, indented for enhanced bonding, and spiral ribbed for optimal frictional engagement. The cold-drawing variant is unparalleled in its ability to reinforce and enhance the durability of prestressed concrete structures.
Raw Material Requirements
Our premium prestressed concrete wire is built upon the exceptional quality of carbon steel wire rods such as SWRH77B or SWRH82B. These rods are meticulously selected to satisfy rigorous standards, ensuring precise size, perfect shape, and exact weight tolerances. They exhibit high-grade chemical composition, refined smelting techniques, and ideal delivery conditions. Critical mechanical properties, minimal decarbonization, and impeccable surface quality of these rods are thoroughly examined to ensure they meet the special requirements necessary for delivering unparalleled performance and reliability.
Our pioneering cooling process, elevated by cutting-edge Sterem technology, achieves an impressive Sotenization rate of over 85%. This precision ensures our coils consistently meet the stringent demands of prestressed concrete steel wire and strands, delivering remarkable consistency and superior 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 expertly engineered to perform with excellence across a myriad of applications. It plays crucial roles in the construction of single and multi-story buildings, highway and railway bridges, durable sleepers, electric poles, high-pressure water pipes, spacious storage tanks, and robust water towers. Its versatility extends to modern high-rise structures, underground constructions, expansive hydraulic projects, intricate maritime constructions, and state-of-the-art airport facilities, including runways and terminals. Designed for industries that demand 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 structural engineering.
