Specifications Introduction
Crafted with precision from superior high-carbon steel plates, our prestressed steel wire undergoes a sophisticated array of processes including acid washing, cold drawing, and phosphating. Our product is versatile, offering two primary types based on production methodologies: the robust cold-drawing steel wire and the stress-relieving steel wire. Designed for diverse applications, it is available in three distinct surface finishes: plain, indented, and spiral ribbed. The cold drawing wire is the perfect choice for significantly enhancing the durability and strength of prestressed concrete structures.
Raw Material Requirements
Our top-notch prestressed concrete is crafted from the highest quality carbon steel wire rods, such as SWRH77B or SWRH82B. These rods must meet exacting standards, including precise size, shape, and weight specifications, superior chemical composition, refined smelting processes, optimal delivery conditions, and outstanding mechanical properties. Additionally, they must exhibit minimal decarbonization and impeccable surface quality. Special characteristics are carefully integrated to guarantee exceptional performance and reliability.
Our innovative cooling process, regulated by cutting-edge Sterem technology, ensures an impressive Sotenization rate of over 85%. This results in coils that consistently meet the demanding standards of prestressed concrete steel wire and strands, delivering unparalleled 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
Engineered to excel across a wide spectrum of applications, our steel wire for prestressed concrete plays critical roles in the construction of single and multi-story buildings, highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its incredible versatility is further demonstrated in modern high-rise buildings, subterranean structures, extensive complexes, hydraulic projects, maritime constructions, and airports, including runways and terminals. It is ideally suited for industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, and for projects that demand extraordinary load-bearing, aesthetic, and functional capabilities in structural engineering.
