Specifications Introduction
Crafted with precision from the finest high-carbon steel plates, our prestressed steel wire stands out, thanks to a sophisticated production process that includes acid washing, cold drawing, and phosphating. Tailored for versatility, this product is categorized into two key types by production methods: the robust cold-drawing steel wire and the stress-relieved steel wire. To meet varying application needs, it is available in three distinct surface finishes: plain, indented, and spiral ribbed. The cold drawing wire is the ultimate choice for elevating the durability and strength of prestressed concrete structures, ensuring optimal performance.
Raw Material Requirements
Our top-tier prestressed concrete is built on the foundation of superior carbon steel wire rods, specifically SWRH77B or SWRH82B. These rods are subject to exacting standards, with rigorous criteria including precise dimensions, impeccable shape and weight tolerances, superior chemical composition, advanced smelting techniques, ideal delivery conditions, top-notch mechanical properties, minimal decarbonization, and pristine surface quality. Special requirements are attentively addressed to guarantee matchless performance and reliability.
Employing cutting-edge Sterem technology, our cooling process ensures a remarkable sotenization rate exceeding 85%. This meticulous process ensures that the coils produced meet the stringent specifications demanded by prestressed concrete steel wire and strands, delivering exceptional consistency and unmatched 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 meticulously engineered steel wire for prestressed concrete is designed to excel across a broad spectrum of applications. It plays a crucial role in the construction of single and multi-story buildings, and is essential for highway and railway bridges, sleepers, electric poles, pressurized water pipes, storage tanks, and water towers. Its applications extend to modern high-rise buildings, underground structures, hydraulic projects, maritime constructions, and vital airport facilities, including runways and terminals. This versatile product is ideal for industries requiring super-tall, super-span, super-volume, and ultra-large area constructions, as well as projects demanding extraordinary loads, shapes, and functionalities in structural engineering.
