Specifications Introduction
Crafted from the finest high-carbon steel plates, our Premium Helical PC Wire epitomizes precision engineering, utilizing cutting-edge processes such as precision acid washing, advanced cold drawing, and sophisticated phosphating. This versatile product comes in two specialized varieties based on production technology: the resilient cold-drawing steel wire and the stress-relieving steel wire. Designed to cater to diverse applications, it offers three distinctive surface finishes: plain for seamless integration, indented for superior bonding, and spiral ribbed for optimal frictional engagement. The cold-drawing variant is the ultimate choice for enhancing the durability and robustness of prestressed concrete structures.
Raw Material Requirements
Our premium prestressed concrete wire is crafted from exceptional carbon steel wire rods such as SWRH77B or SWRH82B. These rods are meticulously selected to meet stringent standards, ensuring precise size, perfect shape, and exact weight tolerances. They are characterized by high-grade chemical composition, refined smelting techniques, and ideal delivery conditions. The rods' outstanding mechanical properties, minimal decarbonization, and impeccable surface quality are rigorously scrutinized to ensure they meet special requirements for unmatched performance and reliability.
Our innovative cooling process, powered by the cutting-edge Sterem technology, achieves an impressive Sotenization rate of over 85%. This 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 deliver exceptional performance across a wide range of applications. It plays crucial roles in constructing 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 buildings, underground structures, large-scale hydraulic projects, complex maritime constructions, and cutting-edge airport facilities, including runways and terminals. Designed for industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, it is ideal for projects that demand extraordinary loads, unique shapes, and specialized functionalities in structural engineering.
